  • Platform for the analysis of micropollutants in the environment - IFSTTAR GERS

    The platform for the analysis of micropollutants in the environment provides IFSTTAR with experimental and analytical capabilities in the disciplines of environmental chemistry and soil hydrodynamics. It owns a large number of devices that enable it to perform every task from the taking of samples to analysis, with a particular focus on trace metals. In the field, the laboratory has at its disposal multiparameter probes and a portable X-ray fluoresence analyser for soils. Its laboratory analyses can call on ultraviolet–visible spectroscopy, ionic chromatography, and laser particle size analyser for the characteristic parameters of water and soils and an optical emission spectrometer and an inductively coupled plasma mass spectrometer for mineral micropollutants, for which speciation is conducted by physical separation or X-ray microfluorescence.

     

    This facility is managed by GERS (Geotechnical Engineering, Environment, Natural Hazards and Earth Sciences Department)

  • Platform for the multi-scale analysis of soils, rocks and geotechnical structures - IFSTTAR GERS

    The platform for the multi-scale analysis of soils, rocks and geotechnical structures allows IFSTTAR to conduct tests on geotechnical structures and their environment as well as natural hazards (erosion, drought, ground movements, weathering of rock and rock risks). It contains a large number of conventional and innovative devices for the laboratory testing of soils and rocks (several test cells, in particular triaxial, cyclic triaxial and high pressure triaxial, odometers, foundation instrumentation systems, in-situ testing, etc.), as well as a number of advanced devices such as an environmental scanning electron microscope (ESEM) and an X-ray diffractometer

     

    Photos of these devices can be found on the website of the SRO (Soils, Rocks and Geotechnical Structures Laboratory), which is part of GERS (Geotechnical Engineering, Environment, Natural Hazards and Earth Sciences Department) at IFSTTAR.

  • Platform for the analysis of the mechanical properties of geotechnical materials - IFSTTAR GERS

    The platform for the analysis of the mechanical properties of geotechnical materials allows IFSTTAR to study, in particular, natural soils, treated soils, industrial by-products and sediments. The platform consists of three units. The soil mechanics unit performs the tests that are conducted to identify and characterise soils, whether undisturbed or compacted, saturated or unsaturated. The imaging and physical chemistry unit examines soils at scales ranging from the micrometre to the millimetre, making it possible to identify the reactions that take place between the constituents, particularly in the case of soil treatment. Last, the environmental simulator consists of a climatic enclosure and a ventilation room (winds up to 70 km/h).

  • Photometry and colorimetry platform for testing road signage - IFSTTAR COSYS

    The photometry and colorimetry platform for testing road signage is made up of four test benches: one bench measures the colorimetric characteristics of surfaces, the second characterizes retroreflective materials, the third measures light sources such as those in traffic signals of varibale message traffic signs (VMTS) and the last bench measures the reflective properties of surfaces and is particularly used to characterise pavement materials. The laboratory has several other measurement devices in addition to these benches (luminance meter, spectroradiometer, video luminance meter and a lux meter).

  • Electromagnetic compatibility testing platform (3-D Transverse Electromagnetic Mode Cells…) - IFSTTAR COSYS

    The electromagnetic compatibility testing platform allows IFSTTAR to analyse the quality of GSM-R communications (a type of GSM developed specifically for railway applications and communications) in the context of an electromagnetic interference scenario. The goal is to analyse the impact of certain types of intentional or non-intentional electromagnetic interference that could potentially disrupt communications.

    The test platform consists of a GSM modem, a base station simulator, and a series of couplers. A PC connected to the modem initiates communication with the base station simulator. The couplers then inject electromagnetic interference scenarios via an arbitrary signal generator. The equipment that simulates the base station analyses the received frames and measures the error rate and other signal parameters. Simultaneously, a specific spectrum analyser connected to the couplers analyses spectral occupation and makes it possible to calibrate the ratios between the communication and interference signals.

  • Test bench for light vehicles and engines, with analysis systems for characterising pollutant emissions and energy consumption – IFSTTAR AME

    This facility allows IFSTTAR to characterise the energy consumption of vehicles and engines as well as their pollutant emissions, whether these are regulated or not. The measurements are conducted either on a single roller test bench which simulates vehicle journeys of different types, or an a dynamic engine test bench which installs a real electric motor or heat or hybrid engine in a virtual vehicle, using a device that dilutes and samples exhaust gases and systems that analyse gaseous and particulate emissions (CO, CO2, THC, CH4, NOx, NO, NO2, VOC, PAH, particulates...). On-board vehicle systems are also used to make measurements under real conditions.

     

    This facility is managed by the AME department (Planning, mobilities and the environment).

  • Test benches for measuring the ageing of battery components - Ifsttar AME

    The test benches for measuring the ageing of battery components allow IFSTTAR to study the electrical properties of the batteries used in transport applications and investigate the processes responsible for deteriorating battery performance. The test facility consists of battery cycling benches which apply given charge and/or discharge profiles, temperature-controlled enclosures to control test temperatures and measurement equipment (impedance meter, thermal camera). The facilities designed for accumulators with a voltage of less than 50V and are intended to be used on assemblies of several cells rather than complete packs.

  • Test benches for measuring skid resistance and surface characteristics - IFSTTAR AME

    The main application of the test benches for measuring skid resistance and surface characteristics is to measure the skid resistance of different types of surfaces (road pavements, airport runways, industrial floors, etc.). They provide a set of machines for analysing surface texture, friction and wear. The facility supplements IFSTTAR’s full-scale testing facilities (reference test track and instrumented vehicles).

  • Platform for trialling power electronic components for electric transport- IFSTTAR COSYS

    The platform for trialling power electronic components for electric transport simulates the environmental conditions and conditions of use that apply to power components in order to study the effects of ageing due to thermal fatigue. It consists of active thermal cycling test benches that simulate the ageing of power semiconductors and conduct electrical and thermal measurements. The reference temperatures range from -40°C à +200°C, and the temperature of chips is varied from a few degrees above zero to 100°C. Currents of over 200A can be injected. The investigated damage modes affect semiconductor chips, and assembly and packaging technologies. The tests are applied to silicon-based (IGBT), SiC-based (Mosfets) and GaN-based (HEMTs) components.

  • Platform for measuring the atmospheric emissions generated by civil engineering processes - IFSTTAR AME

    The platform for measuring the atmospheric emissions generated by civil engineering processes collects data on and measures gaseous and particulate atmospheric pollutants. In particular, the facility has instrumented the air stack of a plant that is classified as presenting an environmental hazard and earthworking machines. The scientific aim of the measurements that are made either on a continuous basis or by sampling is to provide life cycle inventories of civil engineering processes (the mining, design and manufacture of materials and the conduct of works).
