Falling Weight Deflectometer (FWD)

The Dynatest Falling Weight Deflectometer (FWD) applies a dynamic load that simulates the loading of a moving wheel. The pavement response is analysed with Dynatest's ELMOD (Evaluation of Layer Moduli and Overlay Design) software to determine the elastic moduli, stresses and strains of each modelled layer. ELMOD reports the weakest layer of failure, residual life and determines the optimum rehabilitation alternatives. The FWD is available as a trailer or a truck mounted version meeting all FWD standards worldwide.
