FWD is used for evaluation of load carrying ability of airfield pavements and highways. It is a device which is equipped with a standard 300 mm diameter segmented plate and coated with rubber pad to help in disseminating the load uniformly.
Test method permits a force amplitude and duration resembling the effect of a heavy moving wheel load and very precise deflection measurements, especially at large distances from the center of the load. The productivity of the FWD regarding pavement surface deflections for an applied load.
Features of the Falling Weight Deflectometer testing tool
The Falling Weight Deflectometer put in a dynamic load that simulates the loading of a moving wheel. The pavement reply is analyzed with software to control the elastic moduli, strains of each modeled layer. It announces the weakest layer of failure, residual life and determines the best rehabilitation choices.
