Falling Weight Deflectometer
FromDynatest
The Falling Weight Deflectometer (FWD) is used by pavement engineers to evaluate pavement conditions and performance, to determine the need for rehabilitation or reconstruction. The data from the FWD can also be used to optimize pavement design and maintenance strategies. The Falling Weight Deflectometer (FWD) is an integral part of the process for structural evaluation of pavements. The FWD is a non-destructive and fast method to evaluate the structural capacity of pavements for research, design, rehabilitation of the road and for pavement management purposes. The Dynatest Falling Weight Deflectometer (FWD) applies a dynamic load that simulates the loading of a moving wheel. The pavement response is analyzed with Dynatest’s ELMOD (Evaluation of Layer Moduli and Overlay Design) software to determine the elastic moduli, stresses, and strains of each modeled 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 (the USA only) meeting all FWD standards worldwide.
