Bearing capacity testing of pavements

Falling Weight Deflectometer

The Falling Weight Deflectometer (FWD) simulates wheel load to evaluate the structural condition of pavements. The measuring principle of the FWD consists of a dynamic load pulse which replicates a heavy goods vehicle. The load force is transferred through a circular plate, which rests on the surface being tested. Deflection sensors measure the deformation of the pavement in response to the load.


FWD testing is a non-destructive and fully automated process. Analytical software helps determine the stiffness, residual life and maintenance plan for the pavement.
