Falling Weight Deflectometer (FWD)

Steadily increasing traffic on the road infrastructure sets high demands for monitoring pavement conditions. The Falling Weight Deflectometer (FWD) is used to obtain Road Bearing Capacity Measurements. These measurements provide input when determining a pavement’s structural capacity and strongly influence ongoing maintenance, rehabilitation and reinforcement requirements. The FWD unit is well protected in the van and leaves room for further equipment or even a small laboratory. Another possibility is to bring along the portable FWD, PRIMA 100. The combination of the traditional FWD equipment and the PRIMA 100 light FWD allows in-situ quality control in connection with rehabilitation of pavements or new construction.

Modular system

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 is to upgrade the equipment from a standard 7-150 kN Falling Weight Deflectometer to a 7-250 kN Heavy Weight Deflectometer
(HWD) or even to a Super Heavy Weight Deflectometer (SHWD) 7-300 kN is to add more weights, a larger
load cell and upgrade software. 

Features

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, 18 geophones
and warning lights.
