註釋

The Dynaflect and the Falling Weight Deflectometer are commonly used for nondestructive testing of pavements. Although in both cases a dynamic load is imparted, the determination of the mechanical properties of the pavement is normally performed by using static analyses. In this study, the displacements obtained from dynamic analyses are compared to those provided by conventional static programs when the subbase is a homogeneous soil stratum of finite depth, resting on a much stiffer rock-like material and when the soil properties increase smoothly with depth, as is often the case.
