Challenges in Sweden

4 2016-10-24


• Started i the 80’s

• Point lasers + inertial measurement

(Laser RST, Profilograph)

• Tradition of strict quality requirements

• -> Historic measurements are

compareable.

5 2016-10-24


Todays modern survey technology:

6 2016-10-24


Todays modern survey technology:

• At least 17 point cross section

• Texture (MPD) in 3 positions

• Measurement and calculation of

parameters accordning to

Trafikverket’s method

7 2016-10-24


• Total paved network approx 80 000 km

• Approx 75 000 km of measurements per year.

– European and National roads every year.

– Other roads every second year.

– Opposite direction every fourth year.

• Usage

– Distribution of funds

– Treatment planning

• Condition based maintanance

• Based on Maintanance Standard

– Monitoring condition, trends etc.

• QC of pavement contracts.

8 2016-10-24


Focus on:

• Edge deformation

• IRI (Right wheel track)

• Rutting

Functional parameters

Effect on safety, comfort, traveltime etc.

9 2016-10-24

• Web based system for showing pavement condition data.

• Designed for everyday use by project managers, consultants and contractors.

• Object level oriented. Find information for a specific road or search data in a region or entire country.

• Road information

– Speed limit, amount of traffic,

type of road etc.

• Pavement information

– History of pavement actions,

type of pavement, thickness

• Condition

– Rutting, IRI, Edge

deformation, etc.

– Photos

• Longitudinal roughness

– IRI right wheeltrack

– IRI left wheeltrack

• Transversal irregularities

– Rut depth

– Rut area

– Rut width

– Crossfall

– Cross profile

– Edge deformation

– Water area

• Texture

– Megatexure, left and right

– MPD, left, middle, right

Swedish Road Performance

Maintenance Standard 2011

• Analysis of national needs

• Target allocation of funds

• Identify road sections as action candidates

Uses quantifiable measurements,

without bias (no subjectivity).


13 2016-10-24




Describes performance by four parameters:– Rut depth

– IRI

– Edge Deformation

– Macro texture

The standard uses traffic class by amount

(AADT) and maximum allowed speed.

Roads where performance compliance are not

met, reported as deficiencies.

The deficiencies can be calculated and are

defined by road class and geography.

Less than 50% of treaments

are triggered by Maintanance

Standard (IRI or Rutting).

Many treatments need to be

performed long before the

functional condition is ”bad”.

Need:

Measure of technical condition.

Surface damage

Structural condition

How?

-New laser technology or

-New use of current technology

18 2016-10-24

Rapid deterioration during

winter

The summer before it was ok

according to measurements!(Would it be possible to predict the

damage?)


19 2016-10-24

Deteriorated surface.

Not always high IRI or Rutting.

Megatexure should be useful.


20 2016-10-24


Focus areas for

development:

• Scanning laser

• Calculate surface damage

with current point laser

technology

Projects are ongoing
