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 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 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.
Assisting in the management, evaluation and preservation of the road network
Our multifunctionals are multifunctional vehicles used for the following applications:
Measures concrete and metal guardrail heights
Measures free heights under structures
Measures superelevation of a formation level and of each lane
SYMAN is a multifunctional device designed and manufactured according to the requirements and needs of road and motorway managers.
SYMAN (SYstème Multifonction d’ANalyse) is a device capable of acquiring in a single pass all the data at the speed of traffic (road and motorway).
This device is equipped with a LIDAR (Lighthouse Detection And Ranging) function that allows the detection and measurement of objects near the pavement or the pavement itself continuously in the traffic flow.
The Plate Compactor – BBPAC, is a co-developed mlpc laboratory device which meets the criteria of the NF EN 12697-33 standard of (09/2007). It is used for the following applications:
The preparation of homogeneous slabs of bituminous mixtures usable:
Directly for rutting tests.
After sawing or core sampling for tests such as direct or indirect tensile modulus, tensile-compressive modulus, complex modulus, 2 and 4 point bending fatigue.
The plates thus produced are representative of the materials compacted in situ in terms of homogeneity and distribution of constituents and voids.
The SCRIM is a device that meets the NF P 98-220-3, NF P 98-220-4 and ISO 13473-1 standards as well as the test method n° 50-2 of IFSTTAR, and is used for the following application:
The SCRIM® (Sideway force Coefficient Routine Investigation Machine) is used to determine the skid resistance of a carriageway.
