Abstract
A falling weight deflectometer operates with a falling weight, transmitting shock energy upon its fall to an intermediate weight and to a holder for a pressure plate engaging the ground. Between the falling weight and the intermediate weight is interposed a shock absorber of elastically yieldable material such as shock absorbing rubber, and a corresponding shock absorber is interposed between the intermediate weight and the holder.
