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:
The ASTRA is a multifunctional device that allows in a single pass to acquire all the data or measurements necessary to evaluate or issue a road diagnosis.
This modular, high-performance condition survey system meets the needs of road network managers by offering them a tool for easy laying.
Dynaplaque 2, vehicle mlpc which meets the criteria of standard NF P 94 117-2 will be used for the following applications:
• Measurement of the deformability of earthworks formation level and capping layer.
• determination of their homogeneity during construction.
• assessment of the bearing capacity and fatigue behaviour of structures such as parking lots, construction site tracks, forestry or agricultural lanes.
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.
The fatigue machine – M2F, is a co-developed mlpc laboratory device which meets the criteria of the NF P 12 697-22 standard. It is used for the following applications:
To carry out fatigue resistance tests on 2 trapezoidal specimens of bituminous materials.
To measure the complex modulus on 2 trapezoidal specimens of bituminous materials, using a precise enclosure (isothermal).
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.
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.
The Shear Press – PCG 3, is a co-developed mlpc laboratory device which meets the criteria of NF EN 12697-31 as well as SHRP criteria. It is used for the following applications:
It allows the study of the compactibility and the production of specimens.
The compaction effect is obtained by the action of compression on a cylindrical specimen whose axis describes a cone with a vertex coinciding with the centre…
The IMAG is the reference device for the measure of the IRFI (International Friction Index on airport runways), a device licensed by Aéroports de Paris which meets the criteria of the ASTM E2100-04 standard, and which is used for the following applications:
An operational evaluation of winter season skid resistance in operating conditions.
A functional evaluation of skid resistance outside the winter season (water film measure).
The IMAG has been approved as a continuous skid resistance measuring device by the Civil Aviation Technical Service / Directorate General of Civil Aviation, in accordance with the TAC decree of 10 July 2006.
The IMAG complies with the recommendations of ICAO Annex 14.
The laboratory mixer – BBMAX, is a co-developed mlpc laboratory device which meets the criteria of the NF-EN 12697-35 standard of (09/2007). It is used for the following applications:
It allows the preparation of relatively large samples of any coated material in the laboratory for subsequent testing on:
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.
