Abstract :
In portable falling weight deflectometer (FWD-light) tests, the impact load and the deflection generated by means of a weight dropping on a loading plate are measured by the strain gauge type load cell and accelerometer, and are applied for nondestructive evaluation of the ground strength. In this paper, the techniques used in the load and the deflection measurements in the FWD-light system are presented.
