Project Case
The modular principle means that there is no need for investment in new equipment if the demands on the equipment change. All that is necessary to upgrade the equipment from a standard 7-150 kN FWD to a 7-250 kN Heavy Weight Deflectometer (HWD) or event to a 7-300 kN Super Heavy Weight Deflectometer (Super HWD) is to add more weights, a larger load cell and upgrade software. The trailer-mounted FWD can also be integrated in a van without having to invest in new basic measuring equipment.
The standard trailer-mounted FWD is supplied with personal computer, Windows FWD software, time history module, transport lock, DMI (Distance Meter Indicator) integrated in the software, three temperature sensors, four-split loading plate, 9 to 17 or more geophoness and warning lights. Additional functions can easily be added such as video or marking equipment, GPS (Geographic Positioning System), which allows presentation of data in maps or general plans of site.
For data treatment Grontmij supplies RoSy DESIGN, a back-calculation software for both road and/or airport data analysis. However, files generated from the equipment can be applied in any other back-calculation program.
