The development and practical application of the falling weight deflectometer (FWD) which is a nondestructive testing equipment to define the shape of deflection basin, are described. The estimation of the structural condition of the pavements in Nagaoka city, Niigata prefecture is performed. The procedure is based on multilayered elastic theory to backcalculate elastic moduli from FWD deflection data. The study has indicated that it is possible to evaluate structural defect without destroying the pavement.
