1 Interpretation of Falling Weight Deflectometer data Animesh Das1 Introduction In Falling Weight Deflectometer (FWD) test an impulsive load is applied on the road surface. The magnitude of the load, duration and area of loading is so adjusted that it corresponds to the effect of loading due to standard axle on in-service pavement (Sebaaly et al. 1991). The instantaneous deflections of the road surface is measured at a number of points at different distances radially outward from the centre of the Falling Weight . Thus, the shape of deflection bowl is obtained.
