NF 98 218-3 ISO 8608 EN 13036-6 :2008


Continuous measure of the longitudinal evenness

The APL, an mlpc vehicle which meets the criteria of the NF 98 218-3, ISO 8608 and EN 13036-6:2008 standards, is used for the following applications:

  • The APL -profilometer- system allows the continuous measure of the longitudinal evenness of road carriageways and aeronautical runways and, more generally, of any lane used by motor vehicles, whatever the structure of the carriageway and the nature of its overlaying.
  • The measure is based on a survey of the longitudinal profile of the pavement, in one or two traces: the analysis of this profile makes it possible to deduce the evenness characteristics of the pavement surface.

APL 2015 is a longitudinal evenness data processing software package.

Processing of longitudinal evenness data

APL 2015 is a software package for processing data that are collected by a longitudinal evenness condition survey device (APL, MLPL, Unibox). The purchase of this software package is independent of the acquisition of condition survey equipment.

APL 2015, which complies with the 2015 Technical Note and the 2014 Uni Guide, is available under several licenses; they depend on the measurement equipment used:

– APL2015 License – APL Data

– APL2015 License – MLPL Data

– APL2015 License – Unibox Data

NF EN 1436


Continuous checking of day and night visibility of road markings

The ECODYN 3, a compact mlpc vehicle which meets the criteria of European standard NF EN 1436 is used for the following application:

  • Continuously measures the coefficients of retro-reflective luminance of road markings as well as their day and night contrasts in relation to the pavement.

This helps the manager to program his/her renewal campaigns, to control the quality of the laying of the road marking products, and to follow their development over time.

Falling weight deflectometer

The HWD/FWD is a device for determining the bearing capacity of pavement. It is composed of a falling weight that generates an impulse loading on the pavement surface by means of a rigid plate and a damping system.

The deflections generated are measured by means of geophones placed under and around the plate.

Measure of the longitudinal force coefficient

Griptester is a Findlay Irvine vehicle which will be used for the following application:

  • The measure of a longitudinal force coefficient (LFC) between the overlaying and a tyre based on the principle of a braked wheel with a constant slip rate of about 15%. This slip rate, which generates the skid resistance, is obtained by mechanical drive between the two carrier wheels and the measure wheel.

NF P 98-218


Continuous measure of the longitudinal evenness

The MLPL is a vehicle for pavement condition survey that meets the criteria of standard NF P 98-218 will be used for the following applications:

The MLPL system is a non-contact longitudinal profile measureing device co-developed by VECTRA, now NextRoad Engineering and IFSTTAR (formerly Laboratoire Central des Ponts et Chaussées). This laser profilometer can be integrated into a single or multi-function vehicle (and is APO compatible). Its metrological qualities are equivalent to those of the APL profilometer. As such, the MLPL is – like the APL profilometer- approved for the acceptance of wearing courses after construction. The measure can be carried out at a speed between 36 and 130 km/h, on dry or slightly wet roads.

The system can integrate the measurement of the macrotexture.
