well as environmental and social,

Until relatively recently, concepts such as "sustainability", "green

transport" and "greenhouse gas emissions" too often tended to be

dismissed as the doomsday ravings of a few deluded fanatics

preaching that the end of the world was nigh.

Today, confronted with unprecedented challenges to our global

climate and economy, we are acutely aware that, without a rapid

shift towards more forward thinking and sustainable lifestyles, we

may indeed be on the verge of a major planetary reckoning.

Hard facts and mounting scientific evidence have replaced the

extremist preaching.

Alongside other sectors, the transport industry must assume its

share of responsibility. The seriousness of the situation calls for our

sector to rise to the challenges and opportunities of the emerging

green economy, so as to reduce the road industry's impacts on the

environment and enable it to contribute pro-actively to a more

sustainable future.

Already, modern road transport systems increasingly reflect the

commitment of road builders, scientists and city planners in these

respects - as well as their growing ingenuity in efforts to ensure

and safeguard a better living environment. Sustainability is

becoming a major watchword, not only at the design phase but

also in the construction and implementation stages of road

schemes. The potential effects of a given road on the environment

are assessed in terms of visual, landscape, biodiversity and other

possible impacts. Factors such as recycling of materials as well as

risks of water contamination, noise pollution and greenhouse gas

emissions are also comprehensively taken into account, alongside

detailed consideration of appropriate measures to avoid or remedy

any issue that may arise.

Whilst there can be no room for complacency, everything seems to

be moving in the right direction, and we are making encouraging

progress on the path to sustainable roads. The legislative climate is

Intr

oduc

tion changing, materials are being recycled, eco-driving awareness is

being promoted and carbon trading and offsetting are gradually

becoming standard practice. More research is being carried out

and more efficient technologies are being made available to

enhance the sustainability of road schemes. And this is only the

beginning. The necessity of sustainable roads has been firmly

established and universally acknowledged. It is now simply a

matter of how many will follow and how quickly.

This publication highlights a series of projects, products and

practices from around the world that have demonstrated

exemplary commitment to the environment and dedication to road

sustainability. It is hoped that they will help set new standards

throughout the road sector, as well as stimulate ongoing progress.

The featured innovations range from advanced traffic signaling

and pavement recycling right down to wildlife protection systems.

They serve as a first reference compilation of model design

considerations, technologies and research applications.

Furthermore, they provide a comprehensive overview of the

various aspects of environmental impact mitigation as they apply

to the road industry, with the aim of setting practical examples and

establishing a basis for the development of best practices.

It is our hope that innovations like these will guide and further

inspire - not only our industry but also the full range of

stakeholders, including the public sector and governments -

regarding the clear economic, as

benefits of sustainable road schemes and eco-friendly projects.

Next to the manufacturing advantages offered by microprismatic sheeting in

general, this product offers additional benefits to road authorities in reducing

investment and maintenance costs for certain traffic signs, as well as reduced

operational energy cost. This is achieved without compromising road safety in

any way. Traditional reflective sheeting processes are based on a multi-layer

coating process. Lower molecular weight polymers are dissolved in various

solvents, coated and dried, where the solvent needs recycling by condensation

and cleaning, or is simply incinerated or released.

A microprismatic manufacturing process uses higher molecular weight polymers

which are extruded on specially embossed cylinders. No solvents are required.

The ability to use high molecular weight polymers during the manufacturing

process provides a better UV and weather resistant retro-reflective film

construction. This results in traffic signs than offer a longer effective life cycle.

Warranties have increased from a maximum of seven years to ten years or more.

In addition to the benefits attributed to standard microprismatic sheeting,

Diamond Grade DG³ sheeting allows the replacement of illuminated signs with

no negative impact on driver behaviour. Replacing illuminated signs by high

performance retro-reflective signs enables authorities to reduce investment and

maintenance costs, and energy consumption.

Environmental BenefitsMicroprismatic retro-reflective sheeting manufacturing uses an innovative process

that minimizes environmental impacts. It reduces VOC emissions by 97%,

consumes 77% less energy, and generates 46% less solid waste compared to a

traditional, beaded reflective sheeting manufacturing process.

3M Diamond Grade DG³ Reflective Sheeting

The benefits for end users and for the environment can be

illustrated by an Illinois Department of Transportation

(IDOT) road agency case study. The agency have begun

switching out all overhead signs on the state's roadways to

use high performance sign sheeting that will improve

visibility. The new signs will also save the state money by

allowing IDOT to remove lighting fixtures used on

overhead signs. The new signs will be put up as old ones

need to be replaced, so the change-over to the higher

performance reflective sheeting is expected to take at least

10 years. The cost is USD 74,000 per year. Once the project

is complete the state could save USD 1 million a year in

maintenance and energy costs. In early spring of 2006,

IDOT installed new sign sheeting on overhead guide signs

along the Illinois Route 15 corridor in St. Clair County. The

purpose was to test this high performance sheeting for

safety, visibility and cost effectiveness. Due to the success

of this pilot project, IDOT is using the new sign sheeting on

replacement signs on the Upgrade 74 project in Peoria and

Chicago's Dan Ryan expressway reconstruction. The

MIMAR is an AEC initiative to improve the knowledge of road users in the

environmental aspects of roads. In Spain and other countries there is a growing

concern about road accidents in which animals are killed. Such accidents are

serious, not only for the species involved but also for the safety of drivers,

passengers and others along the route. Wild boars and foxes are among the

animals frequently involved in accidents. MIMAR is a map, providing road users

with information on: road sections with a high risk of disturbing animals in their

natural surroundings and, consequently, a high risk of accident involving animals;

areas with a high environmental value, due to the diversity of animals or plants

and protected areas. Using MIMAR, road users can increase their general

awareness and adapt their driving accordingly.

Environmental BenefitsMIMAR is part of a wider AEC project developed as the "Programme for

sustainable road maintenance" during 2006 and 2007, with the support of

European Social Funds and Fundación Biodiversidad. The project promotes

environmental training for road maintenance professionals, by developing

training material and additional information in a specific website. The following

environmental impacts of road maintenance operations were analysed:

atmospheric emissions, noise, residues, water spills, water consumption, energy

consumption, soil, wildlife, vegetation, visual.

AEC is the Asociatión Española de la Carretera - the Spanish Road Association. A non profit organisation founded in 1949 to defend and promote the interests of road builders, it became a public utility in 1998. Its current focus is on: road safety, the environment, new technologies, urban mobility and infrastructure service quality. The Association initiates many activities related to technology, education, social campaigns and research - in the form of congresses, seminars, training courses, publications, and information exchange with similar organisations and companies, both nationally and internationally. AEC has been a member of IRF since 1949; it is also the founder member of the Latin-American Institute (IVIA), grouping research and technology centres in South America, and collaborates with the EU, the European Transport Safety Council (ETSC) and OECD.

For each of these impacts, a detailed set of guidelines were developed in order to avoid or minimize the consequences. For

example, for pavement maintenance operations, the environmental effects relate to air pollution, contribution to climate

change, negative impact for population, animals and vegetation and gas emissions. So the following management guidelines

are suggested: avoid tipping materials from high places; use water to lay dust, especially under windy conditions; avoid high

speeds; inform workers, so they know that burning of residues is forbidden; maintain vehicles to a high technical standard.

Roads are the backbone of a flourishing economy. Thanks to new technologies,

they can be built even more environment-friendly. A major step in this direction is

reducing the asphalt temperatures, which has been achieved by new mixing

technologies. As a consequence, asphalt laying asks for faster compaction

technologies. Ammann provides proven solutions to the construction industry for

both of these new challenges.

Asphalt is an ideal material for the construction of high-quality roads, which

consist of several layers of asphalt and gravel. The preparation of the asphalt is

usually done in a central mixing plant, where minerals are dried, heated up and

mixed with bitumen. The hot asphalt is delivered to the road construction side in

lorries and a paving machine is laying the material on the prepared ground.

Finally compactors effect consolidated layers and durability.

Environmental BenefitsLowering the maximum temperature of the asphalt during production and

mixing allows a reduction of fuel consumption at the mixing plants, since less

energy is needed to heat the minerals and the bitumen. The second advantage

of lower temperatures is the significant decrease of asphalt smoke that

construction workers are exposed to.

The Ammann Compaction Expert (ACE) enables the operator of a roller to

choose the optimal vibration mode on the road construction site. Very fast

compaction is achieved and the current level of compaction is measured

Ammann is a leading supplier of machines, systems and services to the construction industry, with core expertise in asphalt and road building worldwide. Driven by an entrepreneurial spirit, the family-owned business founded in 1869 is now in the fifth generation. Ammann develops asphalt plants integrally, from analysis to construction, to maintenance. In addition, it develops and produces compaction machines. The decentralised service points enable fast reaction times.

constantly. Excessive or over-compaction is prevented and in addition, the energy consumption of the machine itself is

minimized. Ammann's intelligent compaction with high-tech measurement and control equipment therefore is a key

enabling technology for the wider application of low-temperature asphalt.

Mere optimisation of the compaction itself is often insufficient to achieve sufficiently fast compaction. Therefore, today's

compaction machines can be controlled using GPS positioning technology (e.g. ACEplus of Ammann). Real-time displays of

machines' current positions, compaction work done and positions were additional compaction is necessary, allow drivers

and construction coordinators to plan the use of their machines. Staying within the narrower time slot for compaction is

now possible. The combination of intelligent compaction modes, positioning technology and on-machine displays allow the

new low-temperature asphalts to be applied on road construction sites. Energy savings thanks to lower process

temperatures can now be realized.

Environmental BenefitsRunning through Snowdonia National Park, Arup's design of the

A470 trunk road in Wales (previous page) provided a safe and

reliable route for road users and preserved a landscape of lush

pastures and diverse flora and fauna. The Shenzhen Western

Corridor (previous page) demonstrates how the planning, design

and construction of a major road can be completed in record

time without compromising the water quality or cultural heritage

of a region's ecologically sensitive area.

The Bingley Relief Road shows how effective community

engagement and sustainable innovative design can reduce traffic

in urban areas and improve a community's quality of life.

Complex challenges included crossing a protected peat bog -

where direct access for construction plant was denied - and

ensuring minimal disturbance to its delicate hydrological and

ecological balance. Sustainability was at the heart of the design

for the M6 Toll Road. Three million tonnes of sand and gravel

excavated from the site was re-used as special fills and aggregates

for concrete and drainage, saving 400,000 lorry journeys to and

from the site. Measures were taken to mitigate the effects of the

route on the local environment including the translocation of

heath land; the relocation of rare plants and wildlife and planting

over one million new trees and shrubs.

At Arup we demonstrate how well considered infrastructure can

be truly sustainable, improve people's lives, enhance the

environment and leave a legacy for the benefit of future

generations.

Attica Tollway is the 65 km stretch of motorway which forms the Athens ring

road, a pioneer project constructed on a concession basis. It is one of the largest

co- financed road projects in Europe. Attica Tollway has two directionally

separated carriageways, each including 3 lanes, plus an emergency lane. It is a

unique piece of European road infrastructure, since it is essentially a closed toll

motorway within a metropolitan capital where the problem of traffic congestion

had been acute. Additionally, heavy traffic conditions were a main cause of

reduced air quality in the surrounding environment.

Environmental BenefitsAttica Tollway has studied and implemented significant noise protection

measures, depending on the configuration and the requirements of each area.

More specifically, noise barriers have been installed, covering an area of several

thousand square metres, as well as buffer zones, and specially planted slopes and

embankments. In order to constantly monitor the levels of air and noise

pollution, six noise measurement stations and eight air pollution measurement

stations operate at key locations along the motorway. The presence of the

motorway has achieved a significant reduction in air pollution and traffic

noise in the city of Athens by reducing congestion. Studies by the local

authorities suggest significant savings in fuel consumption - as free flowing

traffic moving along the motorway consumes on average 60% less fuel

than that travelling on the local urban network. Extensive sewage and

flood protection works were created to collect superficial water run-off, since the

rapid increase of human activity in the area allowed few remaining natural

receptors. This resulted in enhanced flood protection for Athens, transferring

Motorway concessionaires are actively incorporating environmental mitigation into their strategic objectives, considering the issue at every stage of the project's life cycle (from the design and construction to the operation) and bringing infrastructure up to date with modern day norms and standards, incorporating new technology and management practices. Attica Tollway provides positive examples of how environmental management can be incorporated into the construction and management of a motorway, mitigating the impact on the natural environment and bringing environmental and social benefits to the surrounding area.

Bingley Relief Road, England

M6 Toll Road, EnglandEnvironmental BenefitsThe ecoprofile approach requires the use of indicators to evaluate the environmental/health impacts of a product throughout

its life cycle. Somaro typically look at greenhouse gas emissions (climate change), Volatile organic compound (VOC) emissions,

eutrophication of the aquatic environment (asphyxia of aquatic fauna), energy consumed, potential toxicity and waste

generation. The environmental/health balance sheet for the water-based road paint Typhon show impacts at least 30%

lower than for a typical solvent-based paint. Atmospheric VOC emissions are an impressive 88% lower, especially

during the application phase. The PROSIGN G400 airless line marker shows several clear advantages, compared to other

machines/systems: superior operator ergonomics and safety; excellent application quality; centralised control

station management of the main marking work; optimum reliability, safety and service life; lower noise levels.

The two Ostrea products replace the use of quarry lime - eliminating the need for extraction and much of the raw material

transport. They reduce the use of non-renewable petroleum resources and reduce greenhouse gas emissions by

20% on application and over the whole product life cycle and eliminate packaging waste.

The Caterpillar D7E is a new track-type tractor (bulldozer) with electric drive that

increases dozing efficiency by 25% (cubic meters/liter), and lowers operating

costs by 10%. This revolutionary integrated powertrain reduces fuel consumption

by 10 to 30% and uses fewer parts and fluids during its useful life. The D7E also

helps the environment by reducing CO2 and gaseous emissions. The D7E is an

innovative solution that will impact the customer's bottom line and their

environmental footprint.

Environmental BenefitsThe D7E is an innovative new track-type tractor designed to deliver powerful

performance and precise maneuverability while consuming fewer resources. The

most significant design feature is an AC electric drive train, which replaces the

power shift transmission that is typically used in these size track-type tractors.

Electric drive trains have been utilized in other types of construction equipment

(such as off-highway trucks) and other types of transportation equipment (such

as locomotives). The D7E electric drive train is the first of its kind, specifically

designed to meet the demands of a variety of dozing applications, such as

frequent changes in direction, working in harsh conditions and the need to have

very powerful electrical components in a small amount of space (power density).

In addition to the electric drive train, the D7E features a beltless design. The

accessory systems, like air conditioning and the water pump, are electrically

powered so there is no need to repair, adjust or replace engine belts. Additional

innovations such as a center post cab which is combined with a single lift cylinder

For more than 80 years, Caterpillar Inc. has

and aligned with the exhaust stack and the pre-cleaner,

offer a huge increase in visibility. The cab is larger, it's more

comfortable, and there's a 50% reduction in noise for the

operator.

The D7E improves operating efficiency and this is very

important since finding qualified labor is a significant issue

in the construction industry. New operators can be trained

quickly and can be more efficient in a shorter amount of

time. In addition, the D7E comes grade control ready from

the factory and performs extremely well when a grade

control system is utilized. The grade control system utilizes

either laser or GPS signals to help the operator move the

material in an efficient manner and achieve grade. This

improvement in material \movement was not factored into

the reductions but typically results in an additional 30%

improvement in the time to complete a job (due to moving

the material efficiently).

By 2010 Switzerland's CO2 emissions have to be reduced to 90% of those of

1990 (Federal law on CO2 emissions reduction, 1999). Road construction

companies will contribute to this objective. In line with this common aim, Colas

Switzerland developed in 2006 a new asphalt concrete, which is both economic

and ecologically sound. The new product is a cold asphalt concrete, based

entirely on reclaimed asphalt aggregate - VALORCOL The binder used is also a

cold asphalt emulsion, so there is no need for heat during preparation and

mixing. VALORCOL can be used for sub-base course, base course and, in some

conditions, for surface courses. Asphalt aggregates result from the crushing and

sorting of old road superstructures. Gravels, stones and bitumen parts of the

aggregates are of high and proved quality. VALORCOL is manufactured in a

dedicated and simple plant and laid in a traditional way, using normal

equipment. The thicknesses of the layers are comparable to those of traditional

hot asphalt and depend on the result desired.

Environmental BenefitsResource saving. As it uses mainly reclaimed asphalt, VALORCOL saves natural

resources of gravel and stones, which are becoming scarce. It is commonly said

that the first source of granulates in future could be the old road itself! The use

of fossil resources is limited to the bitumen in the emulsion, which is only some

2% of the final product. Traditional asphalt concrete uses between 4 and 6% of

bitumen. The regeneration of old granulates lessens the need for waste disposal.

Limiting transportation: The sources of reclaimed asphalt are commonly closer

to the road work than a quarry. So transportation of materials can be greatly

reduced.

Colas Switzerland

COLAS was founded in 1927, in Geneva, to exploit the patent for COLd ASphalt - a totally new emulsification process. Colas Suisse Holding SA is now a group of some fifteen companies directly or indirectly active in public works. Today, the COLAS Switzerland group is established throughout the Suisse Romande and is active in road construction and engineering, civil engineering, the production of aggregates and bituminous products and laboratory research.

Energy consumption and GHG emission reduction. Through use of cold emulsion, simply prepared aggregates, and

unheated mixing, energy consumption and emissions are both reduced. For the plant in Geneva, it has been calculated that

the GHG emissions are reduced by 300 tons of CO2 each year, if a mere 10% of its asphalt concretes are replaced by

VALORCOL.

A recent roadworks in the Jura used 12,000 square metres of base course and 3,000 tonnes of VALORCOL. Energy and

CO2 savings of nearly 48% were obtained, compared to the traditional use of transported hot bitumen and extracted

aggregates. The energy saving was equivalent to 530 Swiss families' electricity consumption for lighting during one year. The

CO2 saving was 84 tonnes, which is the equivalent CO2 output of a 30 tonne truck covering 87,000 kilometres.

Tyre pile - a basic source of raw material

International Road Federation Innovative Practices for Greener Roads 19

Traffic noise has been identified as a key concern for the public. Noise emissions

from highways adversely affect the quality of life of nearby residents, create

communication difficulties and lower real estate values. In order to reduce noise,

it is first necessary to understand where these emissions are occurring. Studies

have shown that the majority of noise produced from a highway is due to the

tyre/pavement interaction. The mechanisms by which noise is generated in the

tyre/pavement interaction vary, and will be dependent on the match between

tyre characteristics and pavement properties. However, certain effects are

proven: smooth surfaces are quieter than rough surfaces; porous are quieter than

non-porous; elastic are quieter than non-elastic. ECOPATH has sought to achieve

smoothness, porosity and elasticity in paving surfaces in an eco-friendly way.

The pioneering work done by Charles McDonald in the 1960s showed that that

the addition of finely ground scrap tires (crumb rubber) to asphalt yielded an

excellent crack sealant. Since then, CRM binder has emerged as an efficient and

"green" alternative to conventional polymer modified binders, due in part to a

growing environmental sustainability movement, dwindling natural resources,

increased environmental issues, and the quest for improved paving materials.

Research has shown that crumb rubber modification of asphalt binder has many

similar effects to conventional polymer modification. The major changes noted by

researchers are seen with the increase in the high temperature stiffness, these are

often seen to exceed levels normally achieved by conventional polymer

modification. It is this property that is one of the keystones behind the success of

implementing CRM binder in quiet pavements.

ECOPATH is a leading resource for equipment, process design and formulation technology for asphalt rubber (AR) and polymer modified asphalt (PMA) binders. They are prepared to meet customer needs through their scalable technology transfer package. ECOPATH also provides training, project planning, maintenance programmes and blending equipment to satisfy any modified asphalt paving project or requirements.

Environmental BenefitsOne of the principal reasons behind the success of using CRM binder quiet pavements lies in its ability to maintain the "open"

structure of the open graded mixes typically used in quiet pavements. While conventional asphalt binders are typically more

prone to permanent deformation, CRM asphalt binders have been shown in numerous studies to withstand greater

temperatures without deforming. It is not uncommon for crumb rubber concentrations of 20% to be used in CRM binder

formulations; these high concentrations of crumb rubber explain, in part, the significant increase in elasticity typically seen in

pavements using CRM binder.

The need for improved paving surfaces increases, as populations increase, budgets tighten, and environmental consciousness

gains momentum. Therefore, cutting edge materials are necessary to fulfill these requirements; CRM asphalt binder is a

"green" paving a material which exhibits excellent qualities with respect to these demands. Many US state agencies have

achieved significant noise reductions through the use of appropriate pavement design and CRM asphalt binder. The success

of CRM asphalt binders lies in their capacity to provide improved engineering properties, such as reduced noise,

through an environmentally sustainable process.

The Egnatia motorway is a priority project of the Trans-European transport

network and is the communication link spanning northern Greece from its

western to eastern border. Being a collector axis of the Pan-European north-

south corridors, it is of great geostrategic importance for both the Balkans and

south-eastern Europe. The Egnatia motorway is one of the first large-scale public

works to apply a system of environmental management, that is, a method of

organising and implementing environmental protection and mitigation measures

in the design, construction, and operation stages of the project. This covers

heritage protection, impacts on ecosystems, noise, waste, energy,

cleaning/maintenance/restoration, pollutant gases, and water.

Environmental BenefitsThe Egnatia motorway follows traces of the ancient Via Egnatia. Along its route

and within a 1,000m wide zone, 270 sites of historical interest have been

identified. Egnatia Odos S.A. protected all these, where feasible. The company

works with environmental organisations and scientists to minimise the

motorway impact on ecosystems and fauna. A monitoring programme

for noise is set up in residential districts; where necessary, appropriate protection

measures are applied. The concentration of pollutant gases is continually

measured - even in most of the tunnels; air quality management is a priority

- to protect quality of life and mitigate global warming. Skilled staff gather

and dispose surface waste, based on existing environmental legislation. Action is

taken to limit energy consumption, via: a programme of light measurements

and energy management in tunnels; a regular maintenance programme; a time-

schedule for lighting; limitation of electricity consumption based on timely

Egnatia Odos S.A. is the company responsible for the design, construction, operation, maintenance and exploitation of Egnatia motorway. Egnatia Odos S.A. also manages the design and construction of additional projects and has extended its activities abroad, by participating in international tenders and undertaking contracts for the management and supervision of designs and construction works, mainly of large infrastructure projects.

In 2007-2008, a part of the motorway E34 near Antwerp was rehabilitated with

a double-layered CRCP (continuously reinforced concrete pavement). The

original road pavement of 1977 consisted of concrete slabs, laid on a base of

lean concrete. Although the slabs were initially dowelled, serious step forming

originated at the joints. The road became very uncomfortable, particularly on the

right-hand lane carrying heavy traffic. In recent years there were also increasing

numbers of cracked slabs that had to be repaired. Even if the number of cracked

slabs remained within reason, general renovation became necessary because of

poor driving comfort.

The Roads and Traffic Agency (AWV) of the Flemish Government had drawn up a

list of potentially innovative applications for road-building. The use of recycled

aggregates in road paving was one of them. For this E34 renovation, it was

decided to apply two-lift concrete with recycled aggregates in the lower course.

Continuously reinforced concrete pavement was chosen, thereby giving the best

guarantees of a long and maintenance-free service life. The technique of

double-layered concrete or two-lift paving consists of dividing the concrete

pavement into a bottom lift of approx. 80 % of the total design thickness, and a

top lift of approx. 20 % of the total thickness. The thinner upper course makes it

economically justifiable to use fine, hard but also more expensive stones.

As a result, a high-quality upper course can be obtained with excellent safety and

driving comfort properties. Because the lower course does not reach the surface

the strict polishing resistance requirement no longer applies, and less noble and

cheaper aggregates can be used. This permits the use of recycled aggregates.

EUPAVE, the European Concrete Paving Association, was formed in 2007 to promote all cement and concrete products for transport infrastructure and to publicise to the maximum all technical information related to publications, studies, and worksite visits. The cement and concrete applications include: in situ cast concrete, concrete paving blocks, flags and other pre cast items, hydraulically bound base and sub-base layers, soil improvement and stabilisation and in situ pavement recycling. All transport surfaces are the subject of EUPAVE efforts - from motorways to bicycle paths and from airfield runways and railways to safety barriers and noise-reducing devices.

Maximising Sustainability in Concrete Road Construction

Environmental BenefitsAfter construction, the surface characteristics were

evaluated. The evenness, measured using a Longitudinal

Profile Analyser, was excellent with the exception of some

sections where, in the right-hand lane, the profile had to

match the level of the adjacent old hard shoulder. For the

coefficient of evenness CE 2,5 a maximum value of 35

is required, but 90 % of the results were below 25

and 70 % below 20. The skid resistance was checked

with the SCRIM. The transverse friction coefficient

must be at least 0.48. The results varied between 0.60

and 0.87 with 84 % of them above 0.70.

In terms of rolling noise, a reduction of more than 3

dBA was achieved with the two-lift paving technique

compared to the traditional single-layer exposed aggregate

concrete with a maximum aggregate size of 20 mm.

Eurovia developed GAIA as an environmental decision-making tool for use

by contracting authorities when evaluating the technical solutions proposed by

companies bidding on roadworks projects. Gaia uses recognised, published

European databases. The tool compares the environmental assessments of

different solutions for a given road worksite and utilisation. The system then

calculates the environmental impact of each solution. The impact categories used

to evaluate the solutions are taken from the French NFP 01-010 standard for

construction materials (resource depletion, GHG emissions, atmospheric

acidification, etc.) and from an additional list of "customised" impacts (for

example: local road transport (tonnes/km), excavated materials removed for

recycling, etc.).

Eurovia also created RECYCLOVIA®, an in-situ pavement recycling process

involving the use of a cold bituminous binder, emulsion or foamed bitumen. The

technique can be used to refurbish flexible and semi-rigid pavement surfacings to

a depth of approximately 150 mm.

TEMPERA® is a third current Eurovia product family with large potential.

TEMPERA® is a range of warm mixes that are produced and laid at

temperatures 30°C to 50°C below those of conventional mixes. The TEMPERA®

range is suitable for use in virtually almost all applications - wearing courses and

base courses - whatever the binder, modified and non-modified. Warm mixes are

suitable for all types of traffic, from motorways to urban streets.

Operating primarily in Europe and North America, Eurovia - a subsidiary of the VINCI Group - is a world leader in the construction and maintenance of transport infrastructure. Heir to a century of roadwork tradition, making the most of specialised expertise whilst driving innovation, Eurovia is supported by its 39,000 employees working in nearly 1,000 industrial and commercial entities in 14 countries. Eurovia's activity is centred on four complementary businesses: roadworks, materials production, quality of life developments and infrastructure-related services. Eurovia seeks to go beyond the traditional rôle of a roadworks company. It has developed new business approaches, providing more added value and technical content, meeting new needs voiced by customers and road users. Eurovia's dual ambition is to be the expertise benchmark in its business lines and the special partner of its contracting authorities.

Creating New Methods and Materials for 21st. Century Roads

Environmental BenefitsThe GAIA worksite environmental assessment tool now provides customers with a reliable environmental criterion that can

be used to support decision-making. Beyond the tables of results generated by the system for a given call for tender, the GAIA

tool enables both the roadworks company and the customer to ask the right questions in order to reduce

worksite environmental impact. Specifically, the tool makes it possible to systematically take global warming issues on

board and, for large projects, to make greenhouse gas emissions and resource conservation part and parcel of the

road structure design process. The RECYCLOVIA® process offers substantial environmental benefits: the process

requires no added aggregates; the technique offers energy savings of some 40%; a reduction of greenhouse gas

emissions by 20 to 40%; the worksite generates no waste; the use of a cold technique inherently limits the emission of

odours; there is limited disruption to the surrounding community. The TEMPERA® process is particularly suitable for

urban worksites since disruption to the surrounding community - odours, fumes, delays in re-opening the road to traffic -

during application are reduced. The absence of steam emissions also enhances safety for motorists driving near

worksites. The process lends itself to night work and worksites with long transport times, since the workability of the product

is maintained longer than that of a conventional mix. Over 700,000 tonnes have been laid since 2001. Performance values

measured in-situ have proven equivalent to those of conventional solutions, ensuring the durability of structures using these

products.

The ultimate goal of this tool is multifaceted:

- Performing a detailed environmental analysis

of road projects;

- Setting the stage for a comparative analysis of

various road-building techniques and

materials;

- Optimising the road construction site supply

scheme regarding raw materials providers,

choice of suppliers, delivery locations and

materials transport modes;

- Deriving a detailed estimation of GHG

emissions specifically ascribable to the road

construction industry.

The GHG is designed to be consistent, transparent, and credible in its coverage of emissions sources. It is fully

compatible with International Panel on Climate Change (IPCC) guidelines and the emission standards used are regularly

cross checked and validated. The basis module for road construction and maintenance will be completed with more

specific modules, such as barriers, road signs, ITS and waste. The IRF GHG Calculator tool is available for purchase in

electronic version and as a CD Rom. Updates will be regularly available.

The International Road Federation, in conjunction with a number of technical partners, has designed a methodology for

the calculation and modelling of emission estimates in carbon equivalency for road construction and maintenance

projects. The Greenhouse Gas Calculator aims to harmonise the procedure for calculating CO2 and other greenhouse

gas emissions from road construction projects, with a view to achieving energy savings and rationalising emissions data

reporting. This new tool provides an accurate, consistent and accessible inventory system for companies or

administrations measuring the GHG footprint of their projects. It is a vital addition to the inventory of cost-efficient

solutions.

The International Road Federation (IRF) is a nongovernmental, not-for-profit organisation with the mission to encourage and promote development and maintenance of better, safer and more sustainable roads and road networks. As a unique global platform bringing together public and private entities (from leading civil engineering companies and planners through to government ministries, public authorities, financial institutions and research institutes etc.), we are committed to disseminating timely information and global best practices to enhance knowledge as well as to offer expert knowledge, business opportunities and training.

Founded 60 years ago, the IRF is an important and recognised source of expertise and contacts. Its work is organised around a number of core activities, including notably, a comprehensive programme devoted to Environment. Since the beginning of 2009, IRF manages an important new project, the global Transport Knowledge Partnership (gTKP) a DFID (UK Department for International Development) initiated and funded project which offers a platform for improving road infrastructure and road transport in developing countries and transition economies through knowledge sharing and dissemination of recognised best practices around eight distinct themes, including Environment and Climate Change.

Environmental BenefitsSustainable roads can only be built by practitioners who are

fully aware of the environmental impacts of their activities,

as well as the possibilities for reducing this impact. The new

IRF GHG Calculator will enable this.

The tool is based on an input/output modelling approach.

The calculation model is composed of a simple set of

equations and enables estimating the total GHG emissions

(outputs) generated by each of the identified and quantified

emission sources (inputs). The calculations undertaken refer

to the full life-cycle of the road infrastructure and are

repeated for different scenarios and different construction

techniques. Three basic phases can be identified:

preconstruction, road construction and road maintenance.

Among the data collected, distinctions are drawn between

- The inventory of the emissions sources;

- Data and standards relative to the evaluation of these emissions sources;

- The database of emissions factors pertaining to the set of identified sources.

The calculator's output provides an incentive for innovation and advancement of current construction practices, aiming at

reducing emissions and generating corporate economies. In particular, it will help to identify intensive energy consumption

practices that can be replaced by more energy-efficient techniques and technologies.

The IRF would like to thank its technical partners for their valued assistance in the development of the Greenhouse Gas

calculator: 3M, Ammann Group, COLAS, EPFL, Scott Wilson, Volkmann & Rossbach.

Greenhouse gas emissions, especially CO2 emissions, are the main cause of

anthropogenic climate change. The transport sector is responsible for the highest

increase in greenhouse gas emissions. Within the EU-15 greenhouse gas

emissions rose by 26% between 1999 and 2004 (European Environment Agency,

2006). This development demands clear political decisions at both national and

European levels.

In this context congestion and traffic effectiveness are significant keywords -

because the European Commission foresees a growth of 55% in commercial

traffic and 35% in passenger traffic on European roads in the years to 2015. The

adverse environmental effects of the traffic must be diminished. In trying to do

this, it has to be recognised that upgrading of road infrastructure can be

ecologically limited in its effects and expensive. So traffic management comes

into its own.

Today traffic management consists of traffic lights, key information for the driver

about traffic conditions, and systems for influencing routes and road networks.

The goal for traffic management today is to control driving behaviour and choice

of vehicle, route and departure time. Road user charging can contribute to

achieving that goal. The most appropriate concept uses differentiated fees

according to the vehicles' emission class. An integrated road user charging

system based on GPS/GNSS and GSM/GPRS and DSRC technologies is the

most advanced and suitable solution.

The Kapsch Group was founded in 1892 by Johann Kapsch in Vienna. Its early activity consisted of manufacturing telephones and telegraphs. In the 1970s Kapsch entered the analogue railway communications business. In the late 1980s the company began developing as an international communications solutions group. In the early 1990s it entered the road traffic telematics business, through selective strategic acquisitions in Europe. Since 2002 that business has a worldwide dimension, through establishment of subsidiaries and through further acquisitions.

Environmental BenefitsThe Institute of Transport Studies of the University of Natural Resources and Applied Life Sciences in Vienna published the

results of a study of urban road-user charging on travel behavior, the environment and the economy - Impact Analysis of

Urban Road-Use Pricing on Travel Behaviour, the Environment and the Economy. Reductions in travel times and traffic

volumes achieved by tolling lead to decreased congestion, fuel consumption, emissions, noise and traffic

accidents.

Another study published by the Austrian Institute of Economic Research investigated various measures that can be taken in

the transport sector, such as substantial improvements in public transport, road pricing, increases in fuel tax, and promotion of

bio fuels. Road pricing turned out to be the most effective measure in reducing CO2 emissions.

With a fleet of 7,000 buses and

coaches, Stagecoach Group, a

Michelin Fleet Solutions customer, is

one of the United Kingdom's largest

coach operators.

Michelin Fleet Solutions offers large truck fleets all-inclusive tyre management

services, providing the customer with numerous advantages: instead of buying

tyres, customers purchase travel mileage. Designed for large European and

North American truck fleets, Michelin Fleet Solutions is a full service offer that

includes tyre availability and supply, maintenance and monitoring to provide the

customer with streamlined management, budget control and improved

productivity. The "Fleet Solutions" system is based on the principle of the sale of

a service replacing the sale of a product. It features a new economic model

in which the invoicing unit is the mile or kilometre travelled. The market for this

type of offer is strong since transportation companies strive to focus resources on

their core business, particularly by outsourcing vehicle maintenance. Michelin

Fleet Solutions is a business model well adapted to the current era of high energy

costs. The virtuous circle of sustainable development is in place: top economic

performance goes hand in hand with a lower environmental impact for the

benefit of all.

Environmental BenefitsEnvironmental benefits accrue directly and via advantages for both the customer

and the company. Fewer materials and energy are consumed for more activity.

Tyre performance is optimized, thereby cutting fuel consumption. Fewer end-

of-life tyres need to be recovered, thus reducing energy use and other disposal

costs. Customers know their tyre budget up front and no longer fund their tyre

stock. Former fixed costs become variable costs and the rate of unscheduled

downtime time is reduced.

Michelin is at the forefront of all tyre markets and mobility-related service markets: its mission is to contribute in a sustainable way to progress in the mobility of both people and goods by constantly making travel safer, easier, more enjoyable, more economical and more respectful of the environment. The company in a nutshell: 131, 529 employees; a sales network covering 170 countries; 68 production sites in 19 countries; technology centres on 3 continents (Europe, Asia, North America); net sales of 16.9 billion

Preventive servicing makes it possible to reduce repair costs, thereby reducing the cost price of the service. Servicing time is

reduced - thanks to the preventive work carried out during maintenance, thereby improving vehicle productivity and

helping customers to focus on their core business. For Michelin, fewer tyres are manufactured for an equivalent or superior

activity, with more customers and a good loyalty rate. At the end of the day, the environmental impact of transportation

is reduced. Michelin Fleet Solutions key figures: more than 280 M in sales; more than 500 contracts covering more

than 300,000 vehicles; 850 Michelin employees dedicated to the activity, in 22 countries.

This project is but one example among many, of the work conducted by the

Agency. It is chosen because water assessment and management has not been

accorded its rightful place in the environmental pantheon until relatively recently.

Water management is now a leading concern of the World Business Council for

Sustainable Development, of the World Meteorological Organisation, of national

transport authorities and of academic research. With climate change, unusual

storm events are becoming increasingly frequent. Good design has to cope with

this, in addition to ameliorating the effects of normal run-off into sensitive

receiving areas; both surface and ground water, through better collection,

conveyance and treatment systems. But the starting point for any action has to

be evidence-based decision making.

The starting point for a recent assessment under the Stormwater Management

Programme of the Agency was that road water run-off was considered to

account for 40-50% of urban metal contamination to aquatic ecosystems. A

comprehensive study of vehicle kilometres travelled (VTK), VTK per catchment

area, VKT discharge to surface water, VKT discharge to groundwater and the

regional distribution of waterbody crossings by VTK was modelled for the

national state highway network. Analysis of this data led to identification of

estuarine hot spots in receipt of highway discharge from the Auckland road

network. Based on NZ data, the relative amount of vehicle contamination can be

differentiated from other sources by using a fingerprinting technique developed

from Grafton gully storm water tank which exclusively collects highway

discharge. Analysis of two dependent variables - vehicle-derived (zinc and

copper) and road-derived (polynuclear aromatic hydrocarbons, or PAH). PAH

sources include coal tar, exhaust and pyrogenic origins. Hopane, a steroid found

Not a company, but a Crown entity established in 2008, the NZ Transport Agency brings together the functions of Land Transport New Zealand and Transit New Zealand to provide an integrated approach to transport planning, funding and delivery. Working in partnership with regional and local authorities, the transport industry and communities, the NZ Transport agency is focused on delivering four key outcomes: integration, safety, sustainability and value for money. The Agency provides a vital link between government policy making and the operation of the transport sector.

in bacteria, is found only in bitumen. The ratio of hopane:

PAH is indicative of road-derived sediment from bitumen

surfaces.

Environmental BenefitsThe study showed that PAH concentrations from

predominantly road surfaces is significantly lower

than non-road derived PAH. Based on 50 samples from

five locations the contribution of zinc, copper and PAHs

to estuarine contamination may be much less than

that which was previously expected, when compared

to other urban sources.

Of themselves, such findings are not of immediate

environmental benefit. The benefit derives from the fact

that the relative amounts of contamination may be better

identified, as to source. Such identification is the

building-block upon which public policy, in terms of

any necessary amelioration, may be built. The study

will be expanded to a wider range of road conditions and

receiving environment to further develop the hypothesis.

Conservation of Energy by means of Intelligent Aquifer Utilisation Conservation of Energy by means of

Intelligent Aquifer Utilisation

Asphalt pavements have gained acceptance in recent years as an interesting new

renewable energy source. As asphalt pavements can heat up to 70 degrees

Celsius during solar irradiation, a comparison with solar hot water systems seems

obvious. Given the enormous area of asphalt pavement that is available, the

thermal energy potential therefore appears infinite. This heat can be utilized in

different ways. Generally the energy will have to be stored over seasons, for

example in an aquifer. Several designs have been developed to extract heat from

an asphalt pavement. Most available solutions apply a heat exchanger design by

incorporating tubes in the asphalt pavement. This type of asphalt pavement in

the Netherlands is known as ´asphalt collector´. Demand comes from buildings,

supply from the asphalt pavement. Through the use of an aquifer, the difference

in timing between seasonal supply and demand is covered to a large extent.

Environmental BenefitsIn addition to its energy potential, the advantage in using an asphalt collector is

the maintenance of the pavement. In summer time the maximum temperature of

the asphalt pavement can be reduced so that the chance of permanent

deformation is mitigated. In winter time, it is possible to avoid slippery roads by

increasing the minimum pavement temperature. Snow-free pavement is the

result, requiring no salt or other environmentally hazardous contaminants.

Though these additional advantages of the use of an asphalt collector may be

obvious, interest in such a collector is mainly focused on the energy potential and

In terms of cost-effectiveness, this aspect is most

important. Thus, environmental gains with RES® include

less use of fossil fuel, reduced CO2 emissions and

elimination of use of salt on icy pavements, thus

reducing the environmental impact of salt or other

PB's Highway Sustainability Checklist was selected by the American Association

of State Highway and Transportation Officials (AASHTO) as the winning US entry

in the Sustainable Development category for the 2007 World Road Association's

(PIARC) International Competition. The checklist was developed in response to

growing interest in an objective, non-prescriptive, broad-based tool that would

support the integration of environmental stewardship practices and CSS into day-

to-day highway-related practices. The checklist is a compendium of possible

measures associated with various phases of highway projects-from planning to

design, through construction, operations and maintenance. It is meant to

facilitate decisions about the extent to which highway improvements might

incorporate measures that go beyond satisfying minimum functional

requirements by addressing contextual factors which contribute to sustainability

of the natural, built, and human environments.

Environmental BenefitsSustainability is as much a frame of mind as it is a body of technical knowledge.

The checklist is intended to be used not as a "mechanical" approach to

determining what would make a highway project more sustainable but rather to

instill a frame of mind by triggering questions that may otherwise be overlooked

and debate that might otherwise not occur. The idea is to plan, design, manage,

implement, operate and maintain highways in a way that does not simply avoid

or minimize harm (this is considered necessary but not sufficient) but creates net

benefits that transcend transportation functionality - benefits in terms of the

natural, built and social environments. The fact that so much highway work

involves improving existing facilities that were not necessarily held to the higher

The concept of 'green' roadways and buildings is sweeping the nation. The US

Green Building Council (USGBC) and its initiative for including green elements in

its construction projects is growing in importance for communities. In an effort to

become more environmentally friendly, every owner, engineering firm, and

construction supplier is looking for ways to use new 'green' concepts. Resource

International is at the forefront of this.

Environmental BenefitsThe City of Colorado Springs, Colorado is experimenting with a new pavement

method, Terminal Blend Tire Rubber Asphalt (TBTRA), on select roadways.

The goal was to not only create quieter and safer driving conditions, but also

provide the most durable surface while creating a more environmentally-

friendly atmosphere. After extensive research, the City learned that using

"wet" and "dry" tire rubber asphalt manufacturing processes led to excessive

smoke and aroma being released into the atmosphere at asphalt plants.

However, opting for the terminally blended manufacturing process proved to be

the most environmentally-friendly option. TBRTA is produced in a closed-system

plant, preventing smoke and particulates from entering the atmosphere.

In addition to being smoother, quieter, and safer-particularly during rainstorms,

the TBTRA has proven to have a significantly lower concentration of

roadway pollutants running into the roadside ditches compared to

contaminated stormwater runoff of other asphalt pavement.

Resource International, Inc. (Rii) has been operating since 1973 as a Female Business Enterprise in Columbus, Ohio. As CEO and Chair of the Board, Farah Majidzadeh built a company from the corporate HQ that began in her basement in 1973 into a broad-based, multi-disciplined, professional engineering consulting firm specializing in construction management, IT, and planning and design of buildings and infrastructure projects valued in excess of USD1 billion annually. Today, the Columbus-based corporate headquarters and its branch offices throughout the Midwest and abroad employ over 130 engineers and professionals and list a large roster of completed projects for federal and state government, education, healthcare and sports and entertainment. The firm has received consistent and widespread acclaim for its work. As one example - the Michael A. Fox Highway contract in Butler County, Ohio earned the IRF's Global Road Achievement Award and the American Road and Transportation Builders Association and Transportation Development Foundation's 2000 Globe Award for Environmental Excellence, the Build America Award for the Best New Highway in America, the Excellence in Concrete Paving Award in Ohio and the Quality Asphalt Pavement Award in Ohio. To date, it remains one of the only Ohio projects of its size to be completed ahead of schedule.

Five projects illustrate Scott Wilson's efforts to deliver sustainable road solutions.

They are: the A30 Bodmin to Indian Queens trunk road in Cornwall, UK; post-

consumer tyre rubber in rights of way and road surfacings; and two instances of

the use of hydraulically bound mixtures.

Environmental BenefitsThe A30 trunk road was a single carriageway with flows of 25,000 vpd, well in

excess of capacity. It also severed the Goss Moor National Nature Reserve, a

Special Area of Conservation protected under European Law. The objective was

to produce a solution which reduced congestion and improved road safety

whilst minimising the impact on environmental areas, all within the delivery

target of 5 years from award of the Early Contractor Involvement contract to

completion. The scheme has been commended as an example of cooperation

for the successful delivery of highways projects in sensitive environmental areas.

Continuous dialogue with stakeholders has driven the delivery of a solution

which enhanced and improved the environment.

Scott Wilson led two projects which explored the use of post-consumer tyre

rubber in rights of way and road surfacings. The first, a demonstration project,

involved the development and testing of a number of potential surfacings for

impact-absorbing rights of way. A bridleway in Nottinghamshire (UK) was

reconstructed using recycled rubber, recycled aggregate and quarry by-products.

The trial proved that the use of rubber provides a cost-effective and

durable alternative surfacing which is equally acceptable to cyclists,

walkers, and horse-riders, and can be applied in route maintenance or in full

Delivering The Right Highways Using The Right Materials

route reconstruction. This beneficial approach to using tyre waste has been adopted by the the rights of way

management sector and is being taken forward. The second project involved a desk study and a suite of laboratory testing

on Rubberised Asphalt (RA) to UK standards, using a range of UK materials. Consultation with industry experts for the

purposes of the study led to identification of information on the practical issues associated with RA for road

surfacing applications.

Recycled aggregates from construction and demolition materials (including highway arisings), and quarry by-

products, often perceived as waste material, can be used to manufacture Hydraulically Bound Mixtures (HBMs)

for a range of applications, up to and including base layers within major trunk roads and motorways. WRAP (Waste &

Resources Action Programme) commissioned Scott Wilson to examine the performance of HBMs in road construction and

trench reinstatement. HBMs can be mixed and placed using conventional paving equipment. They have the potential to

increase materials resource efficiency; they reduce demand for traditional primary materials; and they provide cost savings

over traditional primary aggregates. The use of HBMs for trench reinstatement is also the subject of a technical report

prepared by Scott Wilson. Following on from this work, Scott Wilson have undertaken in-situ compaction trials and produced

a guidance document on the use of recycled materials.

Many factors can contribute to traffic congestion. The most basic explanation is

that the number of drivers trying to use the same road is so high that it goes

beyond the road's capacity to handle cars. Unfortunately, the underlying reasons

for too many cars in one place at one time are complicated. University

departments and civil engineers dedicate hundreds of hours to understand how

traffic congestion forms and what can be done about it. The important thing is

to do what needs to be done - quickly. Very often, what needs to be done is to

change the number and availability of traffic lanes.

The QMB innovative system prevents tail-backs at motorway exits, allowing for

rapid movement of the safety barrier delimiting motorway deviations and lanes.

In the USA, the QMB System is used for both construction sites and fixed plant,

where the flow of commuter traffic is in different directions in the morning and

evening. The system involves a machine that shifts the barrier sideways at a rate

of 9 and 15 km/h. The barrier is made from shaped concrete elements very

similar, for example, to the New Jersey guard-rail. The top section is T shaped,

making it possible for the machine to lift barrier elements by a few centimetres,

thanks to a system of rollers that passes under the two side wings.

Snoline was set up in 1955 with the aim of finding a new, easy way to produce long-lasting road markings. The result was the pre-formed tape that today accounts for half the company's turnover, produced in its factory in Trezzo sull'Adda, on the Milan-Venice motorway, 20 kilometres from Milan. The company's mission is to improve road safety. To this end, other types of road marking, plastic and rubber products for lane separators, warnings for drivers and passive safety devices that reduce the consequences of impact with fixed obstacles, have all been developed.

Quickchange Moveable Barriers (QMB)

Environmental BenefitsReconfiguring the roadway to expand the work zone without permanently closing lanes accelerates construction and relieves

congestion. Using the movable barriers system during construction can: reduce congestion by adjusting traffic flow, reduce

accidents due to positive separation, increase work-zone size during off peak periods to increase contractor productivity,

significantly reduce overall construction time which leads to lower costs, reduce fuel consumption and, therefore, air pollution

and carbon dioxide emissions, avoid stress and frustration to motorists and avoid congestion on secondary roads

As a result of a "cradle-to-grave" life cycle analysis (using ISO 14040

methodology) of former traffic light and VMS generations, SWARCO FUTURIT

designed and developed a new traffic signal named FUTURA and a new

generation of VMS. The assessment considered raw material extraction,

processing into semi-finished product, production of finished product, use phase

(incl. energy consumption) and the end-of-life management. For the variable

message sign with a 4x3m freely programmable full-colour display, a use phase

of 10 years, a switch-on rate of 20% and an average brightness of 50% were

assumed in order to calculate energy requirements. For end-of-life management,

the recycling of metals and a thermal treatment of plastics - in accordance with

most European waste regulations - were specified. Since the LED module of the

FUTURA traffic light remained unchanged, efforts concentrated on simplifying

the housing design of the new signal head, with a significant reduction in

material inputs while not compromising the signal's stability. Material extraction

and emissions during the production and recycling phases were reduced, too.

For the VMS, major changes have been made to the sign housing, energy supply,

heating and cooling systems and the LED modules; surface mounted technology

(SMT) based printed circuit boards and components are used for the new

generation.

Environmental BenefitsExpressed in terms of global warming potential (GWP) the overall reduction

achieved by both new product generations compared to the previous ones is

around 60%. The environmental impacts arising from material consumption and

SWARCO, headquartered in Austria, is a growing international group providing the complete range of road safety and traffic management products, systems, services and solutions. As the world's largest traffic signal producer and the number two in reflective glass beads, SWARCO has comprehensive know-how in LED-based signalling technology and road marking systems with excellent night visibility. The group offers innovative solutions in adaptive urban and interurban traffic control, static and dynamic signage, parking, public transport priority, infomobility as well as road marking materials and contracting. A sound environmental approach has always been an important motivation of the Group and its business activities.

production are dominated by the production of the

housings. The optimisation of the housing and related

reduction in material demand for aluminium (VMS) and

polycarbonate (FUTURA) have significantly improved the

result for both phases. The improvements will benefit

SWARCO customers, particularly through reduced energy

needs during the life of FUTURA and the new VMS. But

the principal beneficiary of SWARCO FUTURIT's eco-design

initiative is the environment. The redesign of the variable

message sign will lead to a reduction of 25.5 tons of CO2

emissions over the VMS 10-year life cycle. To put this in

perspective - a modern passenger car emitting 160g of

CO2 per kilometre will have produced 5.5 tons of CO2

having travelled almost 160,000 km, equivalent to 4

journeys around the globe.

Long Island Sound is an estuary where saltwater from the Atlantic mixes with

fresh water from New York and Connecticut rivers. The Sound is 110 miles long

and up to 21 miles wide, and located in one of the most densely populated

regions of the US, with 10 percent of the nation's population living within 50

miles of its shores. Increasing development in the region has resulted in extensive

habitat degradation. Funded by a USD 35,000 grant from the National Fish and

Wildlife Foundation, 45 Transpo's EnviroSafe Modular Catch Basin Filtration

Systems were fitted into storm drains at Veterans Memorial Park in Norwalk CT.

EnviroSafe can be retrofitted to fit flat-grated, combination curb-grated catch

basins as well as curb only inlets. Comprised of a basin housing a filter cartridge,

the unit is mounted at the grate (the point of entry). The large basin traps debris,

while inside the cartridge, the modular construction includes open cell foam that

is treated with an antimicrobial shield. In addition to filtering sediment this foam

is highly effective against microorganisms like bacteria, fungus, and mold. The

subsequent layers incorporate coagulant-based and ion-exchange processes for

filtering hydrocarbons, oils, grease and heavy metals like cadmium, lead, copper

and zinc.

Since 1968, Transpo Industries of New Rochelle, NY, has manufactured and supplied "smart solutions" products for bridges, roads, tunnels, railroad crossings and airport runways. Their safety products and polymer concrete materials are widely recognised for quality and performance. As a long time provider of road surface products, the company has realised another growing demand - controlling storm water run-off. Unchecked growth of impervious surfaces is contributing to exponential increases in run-off volumes and pollutant loadings.

Keeping Run-Off Pollutants Out of Long Island Sound

Environmental BenefitsWhen the filters were cleaned after six months of operation, each filter had an average of 54 pounds of trash, or 15,000

pounds total. Norwalk has been testing influent and effluent for E. coli and oil and gas to determine the efficiency of the

filters and is happy with the quality of sediment removal. If the city can keep sediment from reaching the marina, it will

increase the amount of time between dredging of the harbour. Since the last dredging cost the city approximately USD

250,000, any extension of time between dredging operations is a money saver. The catch basin insert filters are the most

cost-effective solution because maintenance of the filters is a simple task. The time required to clean each filter is 10 to 15

minutes, which is considered quite acceptable. The filters have killed 80-90% of the bacteria that would have entered Long

Island Sound - obviating the need to close beaches and avoiding local shellfish. The various filters have captured the

equivalent of a major marine oil spill. The company has entered a partnership with local municipalities on a coastal education

centre, to teach the next generation the importance of the Long Island Sound ecosystem.

Amphibians - frogs, toads, salamanders and newts - are regarded by many

scientists as early indicators of ecosystem health. Their sensitivity to

environmental change make them one of the first organisms in an ecosystem to

show signs of damage to the broader environment. Amphibians also play a vital

ecological role by moving nutrients - in the form of their own bodies - from rich

aquatic habitats to relatively nutrient-poor adjacent areas. They also serve as a

crucial link in the food chain by eating insects and through being eaten, in turn,

by hawks and foxes, for example. Amphibians make periodic mass migrations,

particularly during their breeding seasons. At such times, local populations can

suffer 50-100% mortality rates from passing vehicles when they attempt to cross

even lightly travelled roads. The road industry has in recent years become aware

of the fact that it can safeguard amphibian populations through special fencing

and the provision of channelled road crossing points.

Environmental BenefitsVR amphibian rescue fences and channels provide safety for amphibians by active

protection with environment and landscape-friendly profiles. They have an

optimal price-performance ratio through use of patented construction kits

assembled by qualified personnel, adapting the products to any topography.

Typically, the animals are held back before they reach the road and then

channelled into tunnels connecting the different parts of their habitat. VR thus

helps to sustain natural species diversity and contributes to the environmental

sustainability of roads, even in natural and unspoiled areas.

Volkmann & Rossbach has contributed to road safety for more than 40 years. Its product range includes mobile steel barriers (such as MiniGuard® and VarioGuard®), guardrail systems, road marking (with paint, tapes, hot and cold plastics and agglomerates), amphibian-protection systems and under-ride protection for motor-cyclists.

VR is made up of different companies for manufacturing and service. They cover the entire range of business activities from product development up to installation, from project design to maintenance.

Amphibian Rescue Fences

The fence system

The Amphibian-Guard® guiding device consists of 400 cm long elements. The steel plates are hot dipped galvanized and so

have an average durability of over 20 years. The elements' height of 40 cm and the overhanging edge of 7cm makes the

system invincible for toads, frogs and also small mammals. The large bottom area forms a vegetation-free running surface that

channels the animals into safe crossing areas. The elements are fitted gap-free so that animals do not get trapped or try to

climb. An additional underground barrier makes it impossible to tunnel under the system. The system can be adjusted to the

topography both vertical and horizontal. The elements can be connected in any angle and so guarantee continuous

assembling even under difficult circumstances.

Additionally, Amphibian Guard® can be combined with a robust wire mesh fence that is invincible for larger animals like wild

deer or boars. This space saving solution protects animals of all kinds and sizes from accident with cars on open roads that

lead through their habitats.

Thus, VR Amphibian Guard® offers an easy, long-lasting and very efficient way to make roads friendlier to the environment.

One of the key causes of pollution and traffic congestion are unplanned incidents

including accidents. Reducing accidents and making our roads safer and

facilitating traffic flow are key elements in promoting efficiency and improving

environmental performance. Transport and travel by sustainable modes is almost

a cultural pre-requisite now, but one of the main challenges for transportation is

of balancing individual benefits with those of society as a whole. For instance

when considering Eco driving (increasing vehicle efficiency compared to fuel

usage). them most fuel efficient route (distance) might appear to be through a

town centre (particularly for vehicles fitted with automatic stop and go systems)

but the town bypass may be a road with fewer junctions and a speed-flow

profile that is much more fuel efficient. There is a risk that urban traffic systems,

or a traffic control room or even in-car systems, can adversely affect the road

users if traffic solutions do not factor in the human element. Often users

experience visual and cognitive distractions, mental overload and a reduction in

awareness of their surroundings. This of course can have negative connotations

for safety.

At WSP Group our global transport planning experts combine with our specialists in civil engineering, intelligent transport systems, and human factors to ensure that we develop and implement sustainable transport and information services and systems for our clients and their customers. Our Group approach to sustainable business operations is mirrored in the advice we provide to our clients to make best use of their, and the world's, global resources. Internally we have pioneered the development of car sharing software, innovative "smart working" initiatives, and working closely with community leaders to promote sustainable living in our local environments.

At WSP our combined approach includes the selective application of Intelligent Transport Systems (ITS) and Human Factors as a way to change behaviour by providing management and information to enable better decision making. The current generation of technology can be evaluated not with just a view to modify if need be but to promote new design ideas. This in turn facilitates next generations of technology that further enhance the safety of 'end' users. It is by understanding all aspects of transport and user behaviour that we are able to develop successful systems and services.
