SECTION-V - MAINTENANCE METHODOLOGY AND PROGRAMME The maintenance methodology and yearly maintenance programme will guide the Maintenance team to undertake the routine & periodic maintenance works of the Project Facilities. This programme is the basic indicator of the intended works by the Maintenance Team over a period of one year. Based on the experiences during the first year of operations, maintenance programme for the second year will be prepared and subsequently shall be revised for the further years.

The road maintenance can be divided in to four basic types.

1. Routine Maintenance 2. Preventive Maintenance 3. Periodic Maintenance 4. Special repairs

5.1 Routine Maintenance:

The Routine Road Maintenance means the group of recurrent activities, which relates to the repair of faults and attention to the road structure and facilities within the entire ROW in the required condition, to ensure the preservation of the asset and the convenience and the safety of traffic. The Concessionaire shall perform all routine maintenance activities along the project road.

Routine Maintenance broadly includes:

(i) Local repair of roadway and pavement like repairing potholes, concrete joints, surface patching, lane markings, raised berms, road marking, pavement cracks by sealing, barricades, railings etc.;

(ii) Replacement of equipment/ consumables, horticultural maintenance and repairs to equipments, pavements, elevated highway, overpasses, bridges, structures and other civil works which forms part of the Project/ Project facilities;

(iii) Maintenance of the approach roads to overpasses and drainages within the project site in accordance with good industry practices;

For routine maintenance works, the Concessionaire shall generally follow the operational and performance criteria specified in the respective IRC/ MORT&H standards and specifications (listed as Annexure-7) for each of the performance



indicators covered under pavement condition survey, roughness and BBD. Where such criteria are not specified in the standards, the Concessionaire, for the purpose of routine maintenance shall set forth such criteria as to conform good industry practice for sound pavement maintenance practices in consultation with the Independent Engineer;

(viii) All traffic signs and markings shall always be kept clear visible and in correct alignment and position,

(ix) Prompt repairs & maintenance of Toll Plaza (x) Regular maintenance of road drainage (xi) Grading of unpaved surfaces and shoulders (xii) Vegetation control – grass and scrub cutting (xiii) Maintenance of side slopes, verges (xiv) Maintenance of bridges, culverts and retaining walls; (xv) Roadside cleaning (xvi) Maintenance of landscaping (xvii) Maintenance of guardrails, fencings (xviii) Provision of traffic and safety control devices during the routine maintenance works or

riding quality; o Protect and prevent failure, deterioration or loss of road pavement and structures; Ensure

that the drainage system functions at all times, o Prevent the growth of harmful vegetation on formation and drains, o Paint and carryout minor repairs to culvert and bridges; o Repair and paint direction and warning signs, parapets, walls and guide posts; Care and

control of trees; and

5.2 Preventive Maintenance:

An organized, systematic process for applying a series of preventive treatments over the life of the pavement to minimize life cycle costs.

This strategy is based on the concept of applying periodic treatments at appropriate times in a pavement’s life is less costly than applying one treatment at the end of pavement’s life. Preventive maintenance programs are designed to slow pavement deterioration. The Concessionaire shall regularly carry out the necessary preventive maintenance activities for the Project Facilities to ensure adherence to the Design Requirements and specifications throughout the Concession period. Preventive Maintenance shall include the activities related to each element and the system as a whole of the Project Highway to ensure that during the Concession Period and at its end, it is in sound, durable and functional condition.

The group of activities which can normally be predicted and planned for by nature, location and extent and are carried out periodically with a view to safeguard the pavement crust and also improve the riding quality.



5.4 Special Repairs:

The group of activities performed to restore the roadway following damage due to natural calamities such as heavy floods, sand storms, hurricanes, cyclones, earthquakes or landslides which shall be unpredictable. The affected Project Highway shall be rectified and the system shall be restored to function as per programme prepared in consultation with Independent Engineer. Typical activities include,

(a) Culvert and bridge repairs (b) Retaining wall repairs and construction; (c) Construction of Diversions; (d) Floodway repairs; and (e) Flood damage restoration works, etc.

5.5 Maintenance Program: Not later than 45 (forty five) days prior to the beginning of each Accounting Year during the Operation Period, the Concessionaire shall provide to the Authority and the Independent Engineer, its proposed annual program of preventive, urgent and other scheduled maintenance (the "Maintenance Program") to comply with the Maintenance Requirements, Maintenance Manual and Safety Requirements. Such Maintenance Program shall include:

(a) Preventive maintenance schedule; (b) Arrangements and procedures for carrying out urgent repairs; (c) Criteria to be adopted for deciding maintenance needs; (d) Intervals & procedures for carrying-out inspection of all elements of the Project Highway; (e) Intervals at which the Concessionaire shall carry out periodic maintenance; (f) Arrangements and procedures for carrying out safety related measures; and (g) Intervals for major maintenance works and the scope thereof.



SECTION-VI MAINTENANCE PROCEDURE 6.1 Pavement/ Carriageway:

6.1.1 Road Maintenance procedure in General:

This section covers the inspection and routine maintenance requirements of flexible and rigid pavements on the project road.

6.1.1.1 Inspection Requirements:

Periodic visual inspections will be carried out at the intervals of six months. These are biannual inspections, which refer to cracking and settlement of the pavement. Every second inspection – being and annual Inspection is a comprehensive visual inspection. They will be coordinated as fully as possible with other Periodic Inspections of other items in the highway as a whole.

Long-term maintenance needs can be determined on the basis of condition surveys, which can take various forms such as:

o Visual rating o Roughness measures o Benkelman Beam Deflection measurement

The entire project road is divided into “links” (of normally one km length). The lengths of Links are defined based on whether the pavement condition is relatively uniform. The riding quality of a pavement shall be measured by a Bump Integrator, which quantifies into physical terms, the overall surface condition of the pavement.

There are number of means of assessing pavement deflection characteristics, of which the best known, in India, is Benkelman Beam, also known as the Deflection Beam. Benkelman Beam deflection gives an indication of the elastic property of the pavement. In newly constructed pavement deflections should be fully elastic and recoverable. On the other hand, old and deteriorated pavements may exhibit greater non-recoverable deflection.

Benkelman Beam measurements might be used as a means of designing the thickness of overlays- survey requirements shall be established by the Maintenance Managers based on the recommendations and assessments of the visual survey.

6.1.1.2 Maintenance Requirements:

This relates to ordinary/ routine repairs to the carriageway. The requirements do not relate to larger scale work needed to enhance the carriageway or to work, which would be classed as, or linked to, structural maintenance schemes like rehabilitation and strengthening.

The need to differentiate between routine and periodic maintenance activities for work that is similar in nature is self-evident. It is usual, before carrying out surface dressing or resurfacing, to ensure that the underlying road structure is sound. This often requires repairs to potholes, rutting, open joints, etc., that would otherwise be carried out as routine maintenance operations, if there was no major structural work following. The repair of defects reported from inspections may be absorbed into structural repairs already due to be carried out, within a planned timescale. However, structural repairs will usually be contained within a long-term programme, determined on the basis of priorities. These schemes are sometimes deferred and this may then make it



necessary to carry out the originally identified routine maintenance repairs separately at relatively short notice.

6.1.2 Surface defects and deformations:

6.1.2.1 Cracks:

Crack sealing will be done in accordance with MORT&H clause 3004. Cracks can be broadly classified as active and passive cracks. The active cracks generally originate from levels below the surfacing while the passive cracks apply to the surfacing. Active cracks have significant movement across the joint both horizontally and/ or vertically. As per this manual, cracks are grouped as follows:

A. Active cracks: (1) Stabilisation cracks (primary cracks in a block pattern developing into secondary

cracking with pumping of fines). (2) Volcano cracks (often stabilisation cracks in low traffic areas like the shoulder). (3) Expansive soil cracks (often parallel to road edge). (4) Longitudinal cracks (settlement/ slip). B. Passive cracks: (1) Surfacing cracks (old and brittle surface or overstressing of the surfacing layer) – not

limited to wheel tracks. (2) Single cracks (long, transverse and random). (3) Alligator cracking (overstressing of base/ sub base) usually with rutting – limited to

wheel tracks. (4) Passive cracks are less easy to identify and care needs to be taken in dealing with them.

Incorrect identification of the causes of such cracks can lead to expensive and unnecessary repairs.

(5) In the repair of open cracks (say> 3mm) hot applied proprietary sealants are frequently used. There is a considerable merit in using “cold” rubber crumb slurry to form a “wet” seal as an alternative. The cold sealant is likely to be easier to handle and control (particularly on rural projects).

Before repairing of the same following will be confirmed,

(1) Cleaning of all cracks wider than 3 mm with hot compressed air will be done prior to its treatment.

(2) Spraying weed killer in the cracks and application of weed kill, if required will be done.

(3) Filling of the crack with a bituminous mixture and/ or over banding the crack with a proprietary brand bandage.

(4) Treating the road surface surrounding the crack where edges have lifted. (5) Cracks in excess of 10 mm will be repaired as per MORT&H specification 3004.

Resource Requirements for crack sealing:

Personnel:

(1) One gang man (2) Labourers (Number as per requirement).

Equipment: (1) Wheel barrows (2) Wire brushes (3) Soft bristles brushes



(4) Block brush (5) Brass brooms (6) Squeegees (7) Cans or appliances (8) Compressor (Number of each equipment will be as per site requirement)

Material: (1) Crayons (2) Primer (3) Asphalt (4) Solvent (5) Sealant

(Quantity will be as per requirement.)

6.1.2.2 Pot holes:

6.1.2.2.1 Permanent Repair: The permanent repair of potholes will be done within a reasonable time as soon as they occur, in accordance with clause 3004, of MORT&H- Filling of Pot holes and Patch Repairs. 3 no’s Maintenance van with following resources shall be maintained which will be ready for movement 24/7 to attend to the patch/pot hole repair/other minor repair and for removal of minor obstructions.

Resource Requirements for repairing potholes: Personnel:

(1) One gang man (2) Eight labourers

Equipment (1) Saw cutting machine (2) Two picks (3) Two shovels (4) One brass broom (5) One wire brush (6) One roller (7) One rake (8) One tape measure (9) And traffic diversion devices, signs

Material (1) Crayons/ Chalk (2) Primer (3) Asphalt (4) Solvent (Bitumen) (5) Sealant

6.1.2.2.2 Temporary Repair: Potholes will be fixed temporarily whenever weather conditions, traffic volumes or high priority other maintenance activities do not allow to perform a permanent repair. The temporary repair will be performed by using cold bituminous mixture, or any innovative technology for these repairs subject to approval of the NHAI.



In case a temporary repair was performed to the quality of a permanent repair, provides adequate driving quality and shows no signs of deficiency up to the end of the second month from notification, the repair is deemed to be taken as permanent repair.

6.2.2.2.3 Detail Procedure for repairing intermittent Potholes: Scope: The work shall include the removal of all failed material, in the pavement courses & if necessary, below the pavement, until the root cause of the failure is removed; the trimming of the completed excavation to provide the firm vertical faces; the replacement of material of at least as high as the standard which was originally specified for the pavement, the painting of tack coat on to sides & bases of the excavations prior to the placing of bituminous materials & compaction.

It shall be in accord with the specification & shall be same type as specified for original construction. Materials used shall never be of lesser bearing capacity or of a greater porosity than the adjacent previous construction.

Preparation of the area of pothole & patch repair:

Each pothole shall be inspected properly & all loose material be removed. The area shall be trimmed with jack hammers or with hand tools suitable for the purpose, such as defective material responsible for the failure is all removed. Layers below the level of the bituminous construction shall be replaced using material of the equivalent grade to specification, including specified methods of compaction. The sides are to be painted with hot tack coat material conforming to clauses 502 & 503 MORT&H.

Backfilling operations:

The mixture to be used in bituminous patching shall be either a hot mix or cold mix in accordance with the appropriate clauses. The mixture shall be placed at max thickness of the layer 100mm (loose) & shall be compacted or rammed as per the specifications. If the area is large the spreading & levelling shall be done using hand shovels & wooden straight edges.

6.1.2.3 Ruts:

Possible cause for rutting: (1) Heavy channelled traffic. (2) Inadequate compaction of mix at the surface or in the underlying course during

construction. (3) Improper mix design, lacking in stability of the mix to support the traffic and leading

to plastic movement laterally under traffic. (4) Weak pavement composition. (5) Incidence of high contact stress caused by heavy bullock-cart traffic. (6) Intrusion of sub grade clay into the sub base course due to shear failure or pumping. (7) Aggregates of surface dressing being pressed into the lower supporting bituminous

layer.

Treatment required: Repair of rutting has been considered a major rehabilitation repair. Intermediate measures can be implemented as directed by the NHAI. Examples are:

(1) Level pavements by filling with hot plant-mired asphalt materials. Follow with thin asphalt plant-mix overlay, or roto-mill and overlay.



(2) Remove plastic mix by milling and replace with stable material. 6.1.2.4 Shoving:

Possible cause for Shoving: (1) Lack of stability in the mix (excessive binder, high proportion of fines, too soft a

binder) in the surface or base course. (2) Lack of bond between bituminous surface and underlying layer. (3) Heavy traffic movement of a start and stop type or involving negotiation of curves

and gradients. (4) Use of non-volatile oil on roller wheels.

Treatment required:

The rectification consists of removing the material in the affected area down to a firm base and laying a stable premix patch.

6.1.2.5 Settlements/ Depressions:

Possible cause for Settlements/ Depressions:

Settlement of lower pavement layers due to a pocket of inadequately compacted subgrade or pavement layers.

Treatment required:

Fill with premix materials, open graded or dense graded, and compacting to a desired profile as the surrounding pavement.

6.1.2.6 Ravelling:

Possible cause for Ravelling:

Ravelling is due to one or more of the following reasons:

(1) Inadequate compaction during construction. (2) Construction during wet weather leading to stripping of binder from aggregates. (3) Construction during cold weather resulting in non-uniform binder film. (4) Use of inferior quality aggregate resulting in fracture, crushing and opening of new faces (5) Insufficient binder in the mix. (6) Ageing of binder leading to brittle fracture and disintegration of pavement. (7) Excessively open graded mix. (8) Poor compatibility of binder and aggregate. (9) Over-heating of mix or the binder. (10) Improper coating of aggregates by binder.

Treatment required:

Ravelled surface has been corrected by adding more quantity of binder, the rate of application depending upon the condition of existing surface and degree of hardening occurred to the binder. If the ravelling has not developed too far, the condition may be corrected by a simple application of cut-back bitumen covered with coarse sand, or a slurry seal can be applied. Where the ravelling has progressed far, a renewal coat with premix material would be necessary.

6.1.2.7 Loss of Cover Aggregate:



Possible cause:

The loss of aggregates can occur due to the following causes

(1) Ageing and hardening (oxidation) of the binder whereby its adhesive property is lost. (2) Stripping of binder from aggregates due to cold or wet weather before, during or

soon after surface dressing. (3) Wet or dusty aggregate to which binder has not adhered. (4) Insufficient binder for the size of the aggregate used or for the existing absorptive

surface. (5) Aggregate having no affinity to the binder. (6) Insufficient rolling before opening to traffic. (7) Fast traffic over new work whipping off the aggregates. (8) Cold-spraying of bitumen or delaying the spreading of aggregates over sprayed

bitumen.

Treatment required:

If the loss of aggregates is due to ageing and hardening of the binder, the condition may be rectified by applying liquid seal, fog seal or slurry seal. If the loss of aggregates has occurred over large isolated areas, the best thing to do would be to provide another surface dressing layer, after carefully cleaning the surface. If the loss of aggregates has taken place in small isolated patches a liquid seal would be sufficient.

6.1.2.8 Streaking: Possible cause:

(1) Use of different qualities of bitumen. (2) Non-uniform application of bitumen. (3) Mechanical faults. (4) Applying the bituminous binder at low temperature.

Treatment required:

Remove the streaked surface and apply a new surface treatment. 6.1.2.9 Edge Breaks & Shoulder Drops:

Possible cause:

(1) Infiltration of water that softens the foundation layers causing the pavement edges to break.

(2) Worn out shoulders resulting in insufficient side support to the pavement. (3) Inadequate strength at the pavement due to inadequate compaction. (4) Lower layer of pavement not being wider than upper layer.

Treatment required:

Affected surface will be entirely removed, rebuild simultaneously and compacted. Adequate slope for draining rain water will be provided with 2% extra slope for shoulder with respect to bituminous surface.



6.1.2.10 Bleedings/ Flushing: Possible cause:

Bleeding can be isolated occurring at intersections, spray joints patches and at random points. Where problems are due to a specific reason such as a construction overspray or steep grade, bleeding will occur over a discrete length. Alternatively bleeding can be extensive over long lengths of road.

Treatment required:

Where bleeding is fairly uniform and free binder is available on the surface, application of cover aggregate of sand would be done. The size of stone, varying from 6mm to 10mm, would depend on the thickness of free binder. Work should be done in the middle of the day during periods of hot weather. Pre-treat the surface by lightly spraying with power paraffin and then brooming the surface to break the oxidized surface and soften the binder. Apply a light application of pre-coated chips, roll well with a pneumatic roller and broom off loose chips. Preheating of the aggregate to 150 0C either in a local asphalt plant or for small quantities in a 200 half drum, assists adhesion. Particularly where large stone is used or the binder film is thin, a tack coat of diluted emulsion at 0.6 liters per square meter may be necessary. A very light application of grit or crusher dust (not natural sand) after chipping helps to lock up the chips under heavy traffic. An open graded premix surfacing with low bitumen content can absorb the excess binder.

6.2 Carriageway Clearing & Cleaning: 6.2.1 General:

The section formalizes the procedure for cleaning activities of the highway. It sets out the cleaning operations, and their frequencies, which are to be undertaken as ongoing operation.

Inspection Requirement: Safety inspections will identify any cleaning requirement on the highway. In addition, Road patrols will also communicate any specific cleaning requirement from time to time. Cleaning Requirement: Cleaning requirements which are identified as a result of safety or Periodic Inspection, Route patrol, other reports and complains or are programmed, will fall into 2 categories:-

Maintenance Requirements: The damage to the embankment or cutting slopes is usually extensive unless checked and maintained at the very beginning of the damage. Any damage to the embankment or slopes should be handled as soon as they are noticed. Any place which has frequent recurrence of any kind of damage would require deeper investigations which should be promptly organized. Depending upon the actual damage the repairs may require reducing the slope angle, clearing the slip material, surcharging the slope, providing a toe wall, turfing, etc. may be necessary. Control of grass, weeds, bushes and trees may be the other activity necessary for repairs of the slope failure. The erosion caused by rainwater or by lack of vegetation cover can be repaired or prevented by providing kerb or channel drains, turfing, drainage chutes, stone pitching, etc. Re-fill and compaction of earthworks to be in accordance with MORT&H Clause 305.2, Embankment construction. It is recognized that in cases where geotechnical investigations have to be undertaken and remedial works designed, it may not be possible to carry out effective permanent repairs within 28 days. Details of any design and analysis carried out will need to be retained for a specified period.

6.3.2 Shoulders:

General: The earthen shoulder will be maintained in such a way that the shoulder drop off will not be more than 25 mm for a length of 10m in a section length of 100m and/ or there will not be any false ditch causing the water to drain in reverse direction i.e. towards pavement instead of away from pavement surface. Inspection Requirements: Periodic Inspections of earthen shoulder will be carried out twice in a year, normally before and after the monsoon season.

Maintenance Requirements: If the shoulders are deformed or scoured and are lower than 25mm from the adjacent carriageway, these will be corrected by excavation, filling, dressing and compacting a material matching the existing material and it will conform to the relevant MORT&H Specifications. In case of earthen shoulder repairs will be carried out as per MORT&H Specifications 3003.

Care will be taken to maintain the same lines and levels and colour and the reinstatement should be to same status as it was prior to the accident. The hoardings or the posters will be removed within reasonable period. In case of repeated incidents the matter will be reported to the police. Paint advertisements will be scraped and the surface repainted within



one week from the date of notice. Corroded areas will be thoroughly cleaned and repainted to match the existing sections. Painting on Guard Rail shall be done on periodical basis or as and when required. Galvanized metal crash barrier/ guardrails will not be painted. In selected areas where they become black due to vehicle exhaust or other reasons, they will be cleaned with soapy water once in a month for plaza area and every 3 months for other areas. Severe damage to long stretches of pedestrian guardrail/ barrier will be repaired using temporary fencing of wire strands to the approval of the Independent Engineer until replacement barriers can be manufactured. Metal crash barrier and guardrails are generally robust and have a relatively long life. Where damaged by traffic they are themselves a hazard. The damaged metal crash barrier/ guardrails will be removed as soon as possible. General replacement of the damaged plates is unusual because of the durable nature of the material used. Posts on the other hand can with time deteriorate significantly (rotting and splitting). An assessment of overall metal crash barrier/ guardrail system condition will be made on an annual basis to identify deterioration and allow early forecasting of any replacement.

6.9.2 Kerb:

Maintenance Requirements: Signs will be cleaned at regular intervals, to suit inspection frequencies. Brackets, bolts and fittings will be tightened and adjusted at the time of inspection. Defects affecting the legality of regulatory or mandatory signs will be treated as Immediate/ Urgent Category. All road signs will be repaired or replaced as per Annexure 4. Any damage to the signboard faces as far as possible will be repaired. When repair is not possible, they will be replaced. The signboard faces will be washed with water and detergent and the bullet holes and other minor dents will be repaired with self-adhesive reflective tapes. Theft sign boards shall be replaced and reinstated as per earlier condition. In case of regular theft or misuse of the facility, appropriate action shall be requested from the Local Authorities with the help of IE/ NHAI, for prevention.



6.10.2 Pavement Marking: General To be effective, road markings must not be obscured due to erosion, they should not have spread appreciably from the original size, they must retain colour, they must have adequate skidding resistance; and, where appropriate, retro reflectivity. Many road markings are used to give effect to regulatory provisions and it is important that their legal status is not affected by undue wear or damage. Inspection Requirements: Periodic Inspections in respect of wear, spread, and colour will be undertaken quarterly. Inspections for adequacy of reflectivity will be carried out during the hours of darkness and should be combined with other similar night-time inspections for road signs, where practical bi-annually. Maintenance Requirements: Pavement marking with thermo plastic paint will be carried out soon after any overlay/ renewal coat is provided. Wherever pavement marking will be damaged due to normal wear and tear, shall be rectified with appropriate material. Pavement markings will be as per IRC: 35-1997.

Road markings will be of hot applied thermoplastic paints as per relevant clauses of Section 803 of MORT&H Specifications.

6.10.3 Reflective Devices, Barriers, Delineator, Road Studs & Blinkers:

This relates to maintenance of reflective and non-reflective safety devices, road studs of all types and colours. Inspection of all road studs for looseness is virtually impossible in terms of both scale and practicability, particularly in those traffic conditions where displacement is more likely to occur. The requirements are that Periodic Inspections for this purpose should, wherever possible, be carried out when lane closures for other activities are in operation. Where displacement is beginning to occur in significant groupings, indicative of a general fault condition, specific closures for road stud inspection should be arranged. Inspection Requirements: Periodic Inspections for retro-reflectivity will be carried out at intervals of six months during the hours of darkness and where possible at the same time as other similar inspections for road and sign lighting, and reflective road markings and signs.

Periodic Inspections for defective or missing road studs will be carried out at intervals of quarterly in conjunction with the inspection of other road marking.

Defects relating to the general condition of road studs are likely to be detected in the first instance by Safety Inspections.




Displaced devices and studs lying on the carriageway, median, hard shoulders or lay-bys and loose road studs, if judged to be a hazard, will be removed immediately where reasonably practicable. Otherwise road users will be protected as far as is possible. The defect will be reported at the earliest opportunity with a request for immediate action to make the defect safe.

The damaged or missing reflective devices will be replaced as a matter of routine maintenance. If the repairs in these items are not possible, all the damaged and missing items will be replaced according to the programme schedule.

6.14 Horticultural Maintenance:

6.14.1 General:


Visual inspections regarding horticulture are performed bi-annually. During routine and periodic maintenance operations the staff will carry out visual inspections and any problems, which are noticed, or any item, which represents immediate or imminent hazard, will be treated with same priority as immediate defects.

Routine and periodic Maintenance:

The scope covers conservation of all trees, shrubs and similar vegetation belonging to project Highway, in the median and within the right of way, if necessary to take adequate and appropriate measures, during the various seasons, and to ensure survival of the vegetation. The casually of plants in the first year of plantation will be re-planted in the successive year preferably during pre-monsoon season to ensure their maximum survival.

Grass cutting shall include the cutting of planted or natural grasses by means of mechanical mowers or by hand, along the main carriageway and in the median. It shall also include hoeing around trees and shrubs within the road/ reserve before the grass is cut and taking care not to damage or disturb the roots of these trees and shrubs during hoeing or grass cutting. Light hoeing shall be done around designated newly planted and young trees and shrubs to protect them from fire and from being smothered by weeds.

Routine and periodic maintenance does not cover the re-plantation of the dead or plantation of the new trees and shrubs, which have become dead/ damaged because of accidents or for other reasons. Such work will be identified during the regular inspection process and will be included in enhancement/ rehabilitation plan.

Routine and periodic Maintenance Frequencies:

The frequencies with which routine and periodic maintenance operations are to be carried out are described earlier. The specified intervals shall be adhered to as closely as possible, although it is appreciated that in order to plan the works efficiently slight variance from target dates may be necessary.

6.14.2 Grassed Areas:

General:

This relates to the maintenance of grassed verges, central medians, shoulders, cuttings and embankment slopes, roundabout islands and other similar areas within the highway. They also relate to those areas, particularly central medians, where the construction is such that the growth of vegetation is specifically excluded.


The inspection of grassed areas shall form part of the periodic inspection of horticulture biannually. The safety inspections and the route patrol however shall provide indication regarding any immediate action required.




Cutting or clearance will be undertaken to safeguard visibility at junctions, median openings bends and accesses, and of signs. As far as possible this will be restricted to once in a growing season at a time that has maximum effect. If, subsequent to cutting, the growth rate is such that adverse safety conditions occur or are likely to occur, a further cut may be made.

A single width swathe cut will be made on verges or central medians adjacent to the carriageway once in a growing season where:

(1) The type and density of growth is such that pedestrians and inspection/ survey

parties would be at risk; (2) The adjacent traffic lane is less than 3.0 m, or where growth, if not cut, would reduce

the effective lane width too less than this. All other cutting of verge areas will be subject to approval and specific grass areas may be selected for cutting up to 4 times per year. In exceptional circumstances, where visual and operational benefits can be demonstrated, certain key areas may warrant more frequent cutting.

Scrub growth clearance will be carried out only where necessary to:

(1) Maintain visibility; (2) Allow access to maintained areas; (3) Remove a specific fire risk that has been identified by a responsible authority.

No other scrub clearance will take place unless agreed. Any scrub clearance will be undertaken outside the nesting season, if possible.



SECTION-VII SAFETY MANAGEMENT

The Safety Management Programme will be ensured principally by all members of the O&M Team. However, the Patrolling team will assure safety of users, workmen and third parties.

7.1 Guiding Principles:

The Safety Policy of the Concessionaire is "Safe use and safe maintenance of the Project Highway". Safety Requirements,

1. Safety Requirements aim at reduction in injuries, loss of life and damage to property resulting from accidents on the Project Highway, irrespective of the person(s) at fault.

2. Users of the Project Highway include motorised and non-motorised vehicles as well as pedestrians and animals involved in, or associated with accidents. Vulnerable Road Users (VRU) include pedestrians as well as riders of motorised two-wheelers, bicycles and other vehicles which do not provide adequate occupant protection.

3. Safety Requirements apply to all phases of construction, operation arid maintenance with emphasis on identification of factors associated with accidents, consideration of the same, and implementation of appropriate remedial measures.

4. Safety Requirements include measures associated with traffic Management and regulation such as road signs, pavement marking, traffic Control devices, roadside furniture, highway design elements, enforcement and emergency response.

7.2 Safety Management Practices during operational period:

Some safety measures to achieve the Safety Policy are:

1. The Concessionaire shall develop, implement and administer a surveillance and safety programme for Users, including correction of safety violations and deficiencies and all other actions necessary to provide a safe environment in accordance with this Agreement. 2. The Concessionaire shall establish a Highway Safety Management Unit (the "HSMU") to be functional on and after COD, and designate one of its officers to be in charge of the HSMU. Such officer shall have specialist knowledge and training in road safety and traffic engineering by having attended a course conducted by a reputed organisation on the subject.

3. The Concessionaire seeks a copy of every FIR recorded by the Police with respect to any accident occurring on the Project Highway. In addition, the Concessionaire shall also coiled data for all cases of accidents not recorded by the Police but where a vehicle rolled over or had to be towed away. The information so collected shall be summarised in the form prescribed by IRC/MOSRTH for this purpose. The Concessionaire shall also record the exact location of each accident on a road map. The aforesaid data shall be submitted to the Authority at the conclusion of every quarter and to the Safety Consultant as and when appointed. 4. The Concessionaire shall submit to the Authority before the 31st (thirty first) May of each year, an annual report (in ten copies) containing, without limitation, a detailed listing and analysis of all accidents of the preceding Accounting Year and the measures taken by the Concessionaire pursuant to the provisions of Paragraph 6.1 of the Schedule- L, of CA, for averting or minimising such accidents in future.

5. Once in every Accounting Year, a safety audit shall be carried out by the Safety Consultant



to be appointed by the Authority. It shall review and analyse the annual report and accident data of the preceding year, and undertake an inspection of the Project Highway. The Safety Consultant shall complete the safety audit within a period of 1 (one) month and submit a Safety Report recommending specific improvements, if any, required to be made to the road, bridges, culverts, markings, signs, road furniture and Project Facilities, including cattle crossings and pedestrian crossings. Such recommendations shall be processed, mutatis mutandis, and acted upon in the manner set forth in Paragraphs 4.3, 4.4 and 4.5 of the Schedule- L, of CA.

7.2.1 Costs and expenses:

Costs and expenses incurred in connection with the Safety Requirements set forth in, Schedule L of the CA, shall be met in accordance with Article 18 from the CA, and in particular, the remuneration of the Safety Consultant, safety audit, and costs incidental thereto, shall be met out of the Safety Fund.

7.3 Traffic Management and Safety:

Traffic management during O&M period is a major challenge because certain restrictions on the movement of traffic are necessary to facilitate maintenance activity.

7.3.1 Traffic Management Situations:

Some situations of Traffic Management are briefly explained below: (a) The warning signs for the construction ahead - will be provided by the sign “Men at

Work” one at the worksite and second at about 800 m ahead to the work zone. In addition, a supplementary plate indicating “Diversion 100 m ahead” and a sign “Road Closed Ahead” will be placed. It will be followed by “Compulsory Turn Right/Left Sign”. The “Detour” and “Sharp Deviation” sign will be used to guide the traffic on to the diversion. All sign boards should be retro reflective as per IRC/MORT&H standards.

(b) Closure for work on one side Carriageway - will be affected by placing various signage of retro reflective type like

1) Men at Work along with distance plate for construction zone 2) Road Narrowing 3) Signs for lane closure 4) Closure of carriageway 5) Keep Left/Right 6) Diversion to the other carriageway 7) Carriageway Closure 8) Sharp Diversion of Route 9) Turn right/Left 10) Two way traffic 11) Carriageway Closed 12) Do not use high Beam 13) Overtaking strictly prohibited. 14) Cones to demarcate the up & down Lane.

(c) Carriageway Repairs - like small works in the middle of the carriageway (minor repairs of potholes, cracks and patches) will be affected by providing signs like

1) Men at Work - placed at 800m before the work zone for approaching vehicle 2) Road Narrows - placed around 600m ahead of work area



3) Keep Left/Right - will be placed at the commencement point of the work zone and next to the barriers for the approaching vehicles.

4) Movable type of barriers with retro reflective paints or tape for night visibility will also be placed on both sides of the work area.

5) Cones or drums will be placed at suitable interval to demarcate the work area. 6) Work Zone Ends - will be installed 120m beyond the work area. 7) If the operation is to continue during night time, necessary lighting arrangements

with flashing lights will be provided.

(d) Safety, Vehicle Breakdown and Accident - In case of unsafe condition, vehicle breakdowns and accidents, the Concessionaire will take necessary precautions like setting up of temporary traffic cones and lights as well as the removal of obstruction and debris expeditiously. The Concessionaire will ensure that any diversion or interruption of traffic is remedied within shortest possible time.

(e) Safety measures during Emergency situations - Arising on account of Force Majeure/ Accidents will be as follows:

• At the points where traffic is to deviate from its normal path, the channel for traffic will be clearly marked with the aid of pavement markings or other similar device. At night back lit signages will be used in combination with delineators and reflective signages wherever required. On the approach of any type of closure regulatory/ warning signs will be installed for guidance of road users. At least two signs will be put up one close to the carriageway where transition of carriageway begins and the other 120 m ahead.

In case of an accident on the Project Highway, the debris (in the form of damaged vehicles and bodies of accident-affected animals and/or human beings) will be cleared from the main carriageway as early as possible after receiving clearance from police and through other applicable statutory procedures.

(f) Safety of Project workmen at Site - Safety measures against accidents to the

workers from traffic using the highway will be by providing helmets and protective chest vests to the workmen. The Concessionaire will insure, as per relevant requirements, all the Project workers against accident.

(g) Other measures to ensure safety - Parking of vehicles on the carriageways leads to accidents many a times, further, the presence of the damage vehicle and/ or debris on the carriageway are the cause of further accidents besides obstructing the smooth flow of the traffic.

For smooth, safe, uninterrupted and normal flow of the traffic on the project highway, Highway Patrolling shall be provided at routine interval.

7.3.2 Traffic Control Zone: In order to plan and provide appropriate traffic management and safety measures, it is necessary to appreciate the concept of a Traffic control zone. A Traffic Control Zone can be defined as an area of the Project Highway which involves the conflict of the right of use between the road users and authority responsible for the maintenance/ improvement of the



Project Highway. From traffic safety point of view, a construction zone comprises four zones as described herein under;

1) Advance Warning Zone 2) Approach Transition Zone 3) Working Zone 4) Terminal Transition Zone

7.3.2.1 Advance Warning Zone:

The advance warning zone is meant to prepare the driver for an alert behaviour and is an essential part of any traffic control system. The warning system shall prepare the driver well in advance by providing information regarding distance, extent and type of hazard ahead so that they can gradually reduce the speed of his vehicle. For the operating speeds on the Project Highway, length of this zone shall be referred in table below. Information in this zone will be conveyed through a series of traffic signs, which will include "Men at Work" and the speed reduction signs at the start and middle of this zone.

7.3.2.2 Approach Transition Zone: The transition zone is the area in which the traffic is steered and guided into and out of the diverted path around the working zone. This is the most crucial zone from safety point of view since most of the movements are turning movements. The traffic in this zone is mostly taken across with the help of barricades and channelizes. The elements for designing this zone are speed of the vehicles, extent of lateral shift and elevation difference between the normal and the diverted paths. The essential safety measures shall include delineation of the travel path and prevention of wayward movements of vehicles by means of barricades channelizes, red cones, and red lamps during hours of darkness etc., as appropriate. In the design of this zone adequate attention shall be paid for providing necessary turning radius of the curves, grade to permit for safe passage of animal driven vehicles, drainage and dust-proofing. Where necessary traffic control shall be affected through manual flagging and by (electrically / Battery operated) traffic lights during hours of darkness. Where vehicles have to wait, the waiting area shall be demarcated by stop lines.

7.3.2.3 Working Zone:

This is the actual area where construction or maintenance activity is taking place and the main concern, therefore, is the safety of the workers at the site from the plying traffic. The path of the traffic must, therefore, be very clearly delineated to avoid intrusion of vehicles moving into the work area. The working zones shall not be close to each other and the distance between the two working zones shall be such that the flow of traffic can return to normal stream by permitting fast moving traffic to overtake slow moving vehicles. The length of all zones shall be basically governed by the speed of approaching vehicles and shall be referred in the table below: Recommended Length of Traffic Control Zones:

Average Speed (Kmph)

Length of Advance Warning Zone (m)

Length of Transition Zone (m)

Length of Working zone (m)

50 100 50

51-80 100-300 50-100 Varies

81-100 300-500 100-200

Over 100 1000 200-300



Recommended Length of Traffic Control Zones The traffic across these zones is guided and taken with the help of various traffic control devices erected at the site. To ensure that moving vehicles are kept separate from workers/ emergency personnel the buffer zones are very essential in the work zone; Longitudinal Buffer Zone: This is the length between the end of the lead in taper of cones (T) and the working space/ work area. It will vary with the speed as shown in table below. Lateral Buffer zones: This is the width between the working space and moving traffic. It will vary with the speed limit as given in table below. The lateral buffer zone safety clearance is



measured from the outside edge of the working space to the bottom of the conical sections of the cones on the side nearer to the traffic. For roads with a speed restriction of 80 Km/ Hr or greater an additional traffic barrier is required at the end of the lead-in taper.

Buffer Zone Safety Clearances (as per IRC: SP: 55-2001)

Speed restriction (Km/h)

Minimum longitudinal buffer zone (L)

(m)

Minimum lateral buffer zone (S)

(m)

50 or less 5 0.5

60 15 0.5

80 30 1.2

100 60 1.2

120 120 1.2

Where an advisory speed limit is in operation, use it (rather than the mandatory speed limit) to determine the minimum longitudinal and lateral buffer zone safety clearances. Wherever traffic speeds are to be reduced, the method must be agreed in advance with the proper authority. Maintenance/ safety Engineer should consider advising emergency services of the location and duration of the works. Working space and safety zones must be provided when personnel are present, but when a site becomes unoccupied it may be possible to make it smaller. This will make it less of an obstruction to traffic. However, if pedestrians are divided into the carriageway, a safety zone must be provided at all times between the outer pedestrian barrier and the traffic. Where the road width is so restricted as to prohibit the provision of the appropriate lateral buffer safety clearance detailed in above table, and diversion of traffic would be impractical, traffic speeds must be reduced to less than 15 Km/ hr and an agreed safe method of working imposed on the site. This method of working should preclude working in the safety zone wherever possible. It must be decided in advance and should be recorded in writing.

7.3.2.4 Terminal Zone: This zone is intended to inform the road users of the end of the construction zone. An information signboard shall be erected to inform road users of the end of construction Zone.

7.3.3 Traffic Management Plan and Lane Closure:

The Highway Patrolling team will undertake the basic regulations of traffic on the spot and in close consultation with the PRO (Public relations officer). For regular maintenance and incident management activities, the standardized pattern of Traffic Management and lane closure will be adopted as illustrated in sl. no. 7.3.3.1. The IE will be informed of the situations requiring added safety like accident, damage due to a Force Majeure event for vetting of the safety measures taken at the spot. However, all the events will be reported by the Concessionaire in the Monthly Status Report. Before the commencement of any major Traffic Management, an overall traffic management plan and programme for the planned/ scheduled activity will be prepared and submitted to the Independent Engineer. The plan will be generally based on the following operational



parameters:

1. At major intersections at all the traffic turning movements will be allowed at all times. 2. Lane closure adopted for diverting the main traffic turning movements will be allowed at most of the times.

Existing traffic may be bifurcated to a one carriage way for going & another for coming For the safety of construction workers as well as the traffic, a physical separation of about 1.5 m between work area and the highway traffic will be maintained by installing coloured drums or safety cones; All construction traffic shall enter and exit the construction site at designated and manually controlled entrances; Adequate advance warning and information signs shall be provided in accordance with IRC/ MORT&H standards and specifications. The mandatory traffic signs together with other necessary cautionary signs will be provided, erected, maintained, repositioned, covered/ uncovered and removed as required in respect of works on the Project Site. Adequate safety during night time will be ensured by providing mobile emergency lighting units with illuminated warning signs of retro reflective type at important locations.

7.3.3.1 Traffic Management Practices: Measures for providing safe movement of traffic in some of the most commonly occurring work zones on highways will be as follows:

7.3.3.1.1 Detour on Temporary Diversion: In the cases of major repairs or reconstruction of cross drainage structures on a highway section, damaged due to flood etc., the traffic may have to pass on a diversion, moving parallel to the highway. A temporary diversion road will basically satisfy the following requirements:

(1) It will have smooth horizontal and vertical profile with smooth vertical and horizontal curves;

(2) It will not get overtopped by flood or drainage discharge under any conditions; (3) It will have adequate capacity to cater for the diverted traffic; (4) It will be dust free and will ensure clear visibility at all times of day and night; (5) It will be provided with the required safety standards; and (6) It will be provided with suitable barricades to prevent intrusion affecting the

movement of the traffic.

The warning for the construction ahead will be provided by the sign “Men at Work” about 600 m earlier to the work zone. In addition, a supplementary plate indicating “Diversion 100 m ahead” and a sign “Road Closed Ahead” will be placed. “Compulsory Turn Right/ Left Sign” will follow it. The “Detour” and “Sharp Diversion” sign will be used to guide the traffic onto the diversion. Hazard markers will be placed just where the railings for the cross drainage structures on the diversion starts

7.3.3.1.2 Closure for Work on one side Carriageway of a 4/6 lane divided carriageway:

The first sign will be for the “Men at Work” along with distance plate for construction zone. Thereafter the sign for “Road Narrowing” will be provided, followed by the signs for lane



closure one after another. This will be followed by sign for compulsory “Keep right/ Left (depending upon site situation). The sign for the “Closure of carriageway” along with that for “keep Left/Right” will be provided at the point from where the vehicle is expected to change the lane for the diversion. The sign for the “Diversion to the other carriageway” will be provided between the “Carriageway Closure” sign and the median gap. The sign for “Sharp Diversion of Route” along with compulsory “Turn right/ Left” will be provided at the location where the gap in median opening starts and traffic is expected to get diverted to the other carriageway. The warning signs for “Two way traffic” along with the plate indicating the distance, up to which the two way traffic is allowed, will be placed at the median, which will be to the left of the moving traffic. Cones or painted drums will be placed for delineation, starting from the sign location for “Carriageway Closed”.

7.3.3.1.3 Carriageway Repairs:

When the work is of small magnitude, to be done in the middle of the carriageway, such as minor repairs of potholes, cracks and patches, then the traffic control measures will mainly consist of providing cautionary signs of “Men at Work”, about 600m before the work zone for the approaching vehicle and other cautionary sign of “Road Narrows”, will be placed at 100m ahead of work area. Regulatory sign of “Keep Left/ Right” will be placed at the commencement point of the work zone and next to the barriers for the approaching vehicles. Movable type of barriers will also be placed on both sides of the work area. Cones or drums will be placed at suitable interval to demarcate the work area. The “Work Zone Ends” sign will be installed 120m beyond the work area. If the operation is to continue during night time, necessary lighting arrangements with flashing lights will be provided.

TRAFFIC CONTROL LAYOUT: - ACCIDENT OR BREAK DOWN (Pictograms not true to scale and layout – only for quick visual reference)



7.3.3.1.4 Traffic Safety Measures during Normal Operation: It is observed that the drivers park their vehicles on the carriageways leading to accidents. Many a times, the accidental vehicles and debris on the carriageway are the cause of further accidents besides obstructing the smooth flow of the traffic. For smooth and normal flow of the traffic on the Project Highway, the actions stated herein under would be taken for the normal operation of the Project Highway.

7.3.3.1.4.1 Highway Patrol:

Highway Patrolling will be done to ensure safe, uninterrupted and smooth traffic flow so that:

(1) No parking of a vehicle on any of the divided carriageway takes place at anytime, police co-operation will be sought as & when required.

(2) Immediate assistance is provided to accident victims and their rescue operation. (3) Minor debris and stalled vehicles are removed from carriageway within reasonable

time after clearance from concerned authorities; (4) In the event of traffic congestion, adequate measures will be taken to mitigate the

same in maximum one-hour’s time and the approaching traffic is duly cautioned about it.

7.3.3.1.4.2 Safety, Vehicle Breakdown and Accident: (1) In case of unsafe condition, vehicle breakdowns and accidents, the Concessionaire will

follow the relevant operating procedures, which will include the setting up of temporary traffic cones and lights as well as the removal of obstruction and debris expeditiously.

(2) The Concessionaire will ensure that any diversion or interruption of traffic is remedied without delay, liaison with Police is done and their co-operation sought to overcome any difficulty.

TRAFFIC CONTROL LAYOUT: - ACCIDENT OR BREAK DOWN (Pictograms not true to scale and layout – only for quick visual reference)

7.3.3.2 Lane Closure:

1. Lane closure is a vital activity during construction and/ or maintenance in the concession period that should be carried out in an organized, planned & disciplined manner. 2. Lane closure involves traffic management in the affected reach of highway & is always a time bound activity. 3. The basic principles to be followed in preparation of planned lane closure shall be;

a. The activity of renewal of pavement surface or strengthening of the pavement structure shall be taken up in a manner so that two lanes are always available to the traffic.

b. The activity of renewal or strengthening shall not be carried out for more then a maximum continuous length and duration as suggested by the IE.

c. Lane closure adopted for diverting the main traffic on account of the traffic management during construction works of the project section shall be governed by the approved programme of construction.

d. Lane closure in short length less than or equal to 500 m, for carrying out a routine maintenance activity shall not be more than a continuous period as suggested by IE.



7.3.4 Traffic Management Devices:

Traffic control devices in the construction zones perform the crucial task of warning, informing and alerting the driver apart from guiding the vehicle movements so that the driver of the vehicle as well as the workers on site are protected and safe passage to the traffic is possible.

The primary traffic control devices used in work sub-zones are signs, delineators, barricades, cones, pylons, pavement markings, flashing lights etc. These shall be in such a way that they are easily understood without any confusion, are clearly visible during day and night, conform to the prevailing speeds in immediate vicinity, stable against sudden adverse weather conditions and are easy in installation, removal and maintenance.

1) Regulatory Signs - These are legal signs erected in consultation with local police and

Independent Engineer. Some of the common types are; a) Do not Enter b) Road Closed c) Give way to Pedestrians d) Speed limit etc.,

2) Warning Signs - These are signs warning the drivers of possible dangers ahead. Some of

the common types are; a) Lane Closed b) Diversion to other Carriageway c) Divided Carriageway Starts d) Divided Carriageway Ends e) Two way traffic etc.

3) Guide Signs - These signs are erected to guide the driver on the detours along the road.

Some of the common types are: a) Diversion b) Road Ahead Closed c) Sharp Deviation of route etc.

4) Illuminated signage - for night time

The main signs would be utilized are shown next (As per IRC: SP: 55-2001). Delineators - Traffic Cones, Drums & Cylinders with retro reflective paint or tapes are used to guide the traffic into a particular lane under conditions of lane closure. The cones shall be placed close enough together to give an impression of the continuity. The spacing ranges from 3m (close) to 9m (normal). Larger size cones shall be used for high speeds or where more conspicuous guidance is required. IRC: 79 (Recommended practise for road delineators) gives details of some delineators.

5) Barricades - To restrict traffic from entering work areas, such as excavations or material storage sites so that protection to workers shall be provided or there shall be a need for separating the two-way traffic. They can be portable or permanent type and can be made of wooden planks, metal or other suitable material. The horizontal component facing the traffic is made of 0.30 m wide wooden planks joined together and painted in alternate colour strips of 0.15 m width and sloping down at an angle of 45 degree in the direction of the traffic.

6) Red/ White striped delineation tape - Shall be used to delineate the work zone from



the traffic.

7) Flagmen - Flagmen shall direct the traffic on stop and go condition, diversion, lane closure etc. and ensure safe movements. The flags for signalling shall be 0.60 m x 0.60 m size, made of a good red cloth and securely fastened to a staff of approximately 1m in length. The sign paddles shall conform to IRC: 67-2001 and provided with a rigid handle. For one-way traffic operation at a time during hours of darkness, battery operated red/ green lights shall be used at either end of the affected section.

The workers working at the height (i.e. structure, building, etc.) shall wear safety belt and shall work with appropriate equipments. Workers working at dusty area shall wear proper mask.



SECTION-VIII: INSPECTION PROCEDURES

All the Project Facilities are inspected as per a predetermined frequency to assess their performance. The inspections will help in planning out the routine and periodic maintenance requirements of the Project Highway. The formats for various inspections (Daily, monthly, quarterly, etc.) presented in the Annexure -5.

8.1 Highway Inspection types:

Broadly, the degree of inspection can be categorized into three levels; (a) Visual Inspection:

Visual Inspections are broad general inspections carried out frequently by the Team of maintenance engineers for road and structures under the guidance of the Maintenance Manager. A report on the obstacles to traffic and fairly obvious deficiencies, which could lead to accidents or maintenance problems, is generated.

(b) Close Inspection:

Close inspections are more intensive and detailed examination of the various elements of the Project Highway and is conducted through visual and/ or by standard instrumental aids for assessment of defects/ deficiencies. The frequency depends on the type/ level of defect or damage. After examining the observations recorded in the formats the Maintenance Manager shall perform a site examination and decide on the remedial action.

(c) Thorough Inspection:

The thorough inspection is of critical importance for bridges, culverts and drainage structures, as well as road pavements during adverse weather condition of monsoon period. It is a comprehensive and detailed assessment of defects/ deficiencies of the Project Highway by visual inspection or with aid of standard equipment and non-destructive testing where necessary.

8.2 Frequency of Inspection:

The type of inspection and tentative frequency of inspection for the various Project Facilities under normal circumstances are as given in the Table below.

ANNEXURE 4 Method statement for Maintenance of Roads

Method of carrying out some of the ‘Ordinary repairs’ or ‘Routine Maintenance’ activities are detailed here under. In detailing the methodologies mentioned hereunder, reference is made to the IRC publications “Manual for Maintenance of Roads” and ‘IRC 82-1982: Code of Practice for Maintenance of Bituminous surfaces of Highways” for guidance and compliance wherever applicable. Wherever the methodology is not clear, good engineering practice shall be adopted in the construction to the satisfaction of the Engineer.

(1) RESTORATION OF RAIN CUTS The work shall consist of restoration of rain cuts by replacing earth in embankment and shoulders, using suitable material, and compacting the same. The area affected by rain cuts shall be cleared of all loose soil and benched. The width of the benches shall be at least 300 mm and they shall extend continuously for a sufficient length. The height of the benches shall be in the range of 150-300 mm. Fresh material shall be deposited in layers not exceeding 250 mm loose thickness and compacted so as to match with the benching at a moisture content close to the optimum. Compaction shall be carried out using suitable equipment such as plate compactors or rammers or by suitable implements handled manually. The finished work shall conform to required levels and slopes. (2) MAINTENANCE OF EARTHEN SHOULDER The work of maintenance of earthen shoulder shall include making up irregularities / loss of material on shoulder to the design level by adding fresh approved soil and compacting it with appropriate equipments or to strip excess soil from the shoulder surface as per the requirement of this specification. Wherever extra earth is required to be added, the earthen shoulder shall be stripped and loosened to receive fresh soil. The deficiency of thickness shall be made up in layers of loose thickness not exceeding 250 mm. Water shall be added, if required, to attain the optimum content and the layer compacted by 80 to 100 KN Smooth Wheeled Roller or Vibratory Roller or Hand Roller or Plate Vibrator or hand rammer to obtain proper compaction. The finished surface shall be to the specified cross slope and line in accordance with the drawing. Wherever the earth is required to be excavated from the shoulder, this shall be done either using equipment like grader or by manual means using hand tools. The resulting surface shall be uniform. If the surface is not to proper lines & levels, it shall be excavated to a depth of 150 mm and the soil mixed with water if required and compacted properly to the lines & levels.


(3) Potholes The Potholes shall be repaired by patching or pothole filling in accordance with MORT&H Specification 3004.2. The area to be repaired shall be cut or trimmed using suitable hand tools or jack hammers. All the defective material shall be excavated and removed. Care shall be taken to see that the excavation is done to a regular shape. The edges of the hole shall be cut vertical. The area shall be cleaned thoroughly using compressed air. Layers below the bituminous construction shall be replaced with material of equivalent specification to the original construction and compacted properly. The area for bituminous construction shall then be applied with either Prime coat or Tack coat or both as per requirement and specifications. The sides are to be painted with hot tack coat material. The bituminous mixture to be used for patching shall be either hot mix or cold mix. The bitumen mixture shall be placed and compacted in layers not exceeding 100mm (loose). The Compaction shall be carried out in layers using roller/plate compactor/hand roller/rammer. While placing the final layer mix shall be spread slightly above the existing surface, so that after rolling it shall be flush with the adjoining surface. During the process of this operation, wooden straight edge shall be used. (4) Cracking Cracks are various types such as hairline, alligator, longitudinal, transverse, edge, shrinkage and reflection cracking and slippage etc.

(a) Cracks less than 3mm in width: If the width of the cracks is less than 3mm, such cracking will be sealed by fog sealing using slow setting emulsified bitumen in accordance with the MORT&H Specification 3004-3. The area to be repaired will be marked by brick piece or chalk. Before applying Fog seal, the area shall be swept/cleaned thoroughly with compressed air jet or scrubbers etc., to remove dust, dirt etc. The surface shall be made clean and dry. The fog seal (a slow setting emulsion) shall be applied at the rate of 0.5 to 1.0 litre/sq.m. The traffic shall be allowed on to the surface only after the seal has set to a non-tacky and firm condition, so that it is not picked up by traffic.

(b) Cracks more than 3mm in width: If the width of the cracks is more than 3mm, such cracked surface will be repaired by filling slow-curing bitumen emulsion preceded by crusher dust (passing 4.75mm but with a maximum of 10% passing 0.075mm sieve) in accordance with MORT&H Specification 3004-3.


For crack filling, slow curing bitumen emulsion & crusher dust are used. The cracks shall be filled to a level approximately 5mm below road surface with crusher dust. After that the surface of the road shall be swept clear of dust and binder shall be poured into the cracks, taking care to minimum spillage. If any excess spillage occurs on the road surface stone dust shall be applied to the excess bitumen until it is blotted. (c) Cracking & settling of surface by more than 10mm: If the cracked portion settles by more than 10mm and its area exceeds 0.5 sqm., such areas will be repaired by patching as per MoRT&H Specification 3004. Patching: The area to be repaired shall be marked and all loose materials excavated. The area to be repaired shall be cut or trimmed using suitable hand tools or jack hammers. All the defective material shall be removed/excavated. Care shall be taken to see that the excavation is done to a regular shape. The edges of the hole shall be cut vertical. The area shall be cleaned thoroughly using compressed air. Layers below the Bituminous construction shall be replaced with material of equivalent specification to the original construction and compacted properly. The area for bituminous construction shall then be applied with either Prime coat or Tack coat or both as per requirement and specifications. The sides are to be painted with hot tack coat material. The bituminous mixture to be used for patching shall be either hot mix or cold mix. The bitumen mixture shall be placed and compacted in layers not exceeding 100mm (loose). The Compaction shall be carried out in layers using roller/plate compactor/hand roller/rammer. While placing the final layer mix shall be spread slightly above the existing surface, so that after rolling it shall be flush with the adjoining surface. During the process of this operation, wooden straight edge shall be used. (d) Cracking & settling of surface by less than 10mm: In case the cracked surface is settled by less than 10mm, the cracks shall be treated as per requirement and then the depression or settlement shall be covered with skin patch up. The area to be repaired shall be marked to a proper shape. After treating the cracks, tack coat shall be applied at a rate of about 0.5 kg/m2. Then bituminous mix shall be placed within the marked outline using a rake and leaving an excess thickness of about one fifth of the depth of depression to allow for compaction. Compaction shall be done by either using roller/plate compactor/hand roller/rammer. While placing the mix, care shall be taken to spread the material slightly above the existing surface, so that after rolling it shall be flush with the adjoining surface. During the process of this operation, wooden straight edge shall be used. (e) Alligator Cracks: In case of alligator cracks, permanent repair by full depth patching will be carried out. The slippage cracks will be repaired by removing the affected bituminous layer and replacing it with


surface patch. The are damaged shall be marked to proper shape carefully. Further operations to repair shall be carried out similar to Pothole patching repair. (f) Edge Cracking: In edge cracking, the shoulders not providing adequate lateral support will be reconstructed with good quality materials. The edge cracking is also to be repaired as per the requirement and condition of crack developed.

(5) Rutting The treatment for Rutting portions shall be carried out as per the directions laid out in IRC 82-1982 and based on sound Engineering practices. The surface showing shear failure or subgrade movement shall be excavated, all loose material removed. The rectification shall be carried out using patching material and similar to patching up operations. (6) Bleeding or Flushing The surface of the pavement affected by bleeding will be treated in accordance with IRC: 82 or any other relevant guidelines in consultation with the IC. If the bleeding is fairly uniform and the surface is free from irregularities, application of cover aggregates or sand shall be carried out. The aggregate used shall be clean, angular and small in size. The aggregate is to be heated and used. If the bleeding surface is having large irregularities, the affected layer shall be removed and replaced with a proper bituminous layer. (7) Skid Hazards The skid resistance of the pavement surface will be maintained. Skid hazards, irrespective of size, will be corrected by improving the surface drainage and skid resistance including cleaning the surface of contamination, surface treatments. (8) Ravelling Ravelled surface is treated with binder, the content of which shall be finalized depending on the pavement condition. If the ravelling has not developed much, application of cut-back bitumen covered with sand or slurry seal can be applied. In cases of severe ravelling, a renewal coat with pre-mix bituminous material is required. (9) Drainages / Side drains The Concessionaire will ensure that all drainage elements and structures are maintained properly without any obstructions. Especially before the onset of monsoon the Concessionaire will ensure


functioning of drainage systems. Any obstruction in the stream beds, vent portions may reduce their normal cross section and impede the free flow of water. Routine maintenance under this category will cover ensuring proper drainage through all CD works, road side drains, drains in slopes, median drains etc. If the side drains / median drains where provided, and other drainage structures have been silted up in such a manner that it is causing obstruction to flow of water, the same will be cleared within 7 days after detection in order to keep the drains free from obstructions all the time. (10) Maintenance of Median & Avenue Plantation Maintenance of Highway plantation will include attending to repairs to elements, connected services as and when necessary, and replacement of irreparable items. Trees will be maintained as per the guidelines in IRC: SP: 21 and no indiscriminate felling of trees will be resorted to. The felling of trees will be undertaken in consultation with the Independent Consultant and after obtaining due permission of the Forest Department, as applicable. Maintenance operations include numbering and maintaining a register of all road side trees within the Right of Way. The routine maintenance will also include trimming and shaping of hedges planted in central median and trees within the ROW, which affect the performance of the Project Highway. Cutting or clearance to ensure visibility at intersections, road bends, accesses and signs will be carried out in such a way as to avoid permanent damage to hedges and trees. Hedges and trees overhanging carriageways will be trimmed to provide a minimum headroom of 5.5 metres above the carriageway at all times. The grass/turf on slopes will be maintained in such a way that the roadway is free of obstruction and the availability of sight distance is ensured at intersections, passing zones, curves etc.
