HWD testing for thick pavements

Heavy Weight Deflectometer

Our Heavy Weight Deflectometer (HWD) can simulate heavy wheel load. From airplanes such as the Airbus A380 and Boeing 777, or transport vehicles such as straddle carriers and reach stackers. The HWD is most suitable for performing bearing capacity testing on thick and stiff pavements, such as airports and container terminals.

Method

The principle of the HWD is similar to the FWD. The deflection of the pavement is measured by applying a dynamic load pulse. The difference between the HWD and the FWD is the maximum wheel load that can be simulated. The HWD can simulate a much heavier load. The testing process is non-destructive and fully automated. Analytical software helps determine the stiffness, residual life and maintenance plan for the pavement.

Modern and fast

QRoad uses powerful and fast Dynatest HWDs. With our team of highly experienced operators, we can guarantee optimal service for every job. You can count on correct and fast execution of fall weight deflection measurements in the field. Ancillary issues, such as office work, are performed immediately before and after the measurements in the same line. So you also never have to wait long for the results of a measurement. On top of that, we are also available 24/7 to take measurements. Year-round.
