抄録

Nondestructive evaluation method of concrete pavement using deflections measured by a Falling Weight Deflectometer (FWD), has been developed. In this procedure, the mechanical properties of a concrete slab and foundation can be obtained by backcalculating from the FWD deflections measured at the slab center. Load transfer efficiency at a joint can be quantified from the FWD deflections measured at the joint. Furthermore, a void beneath the concrete slab can be detected and its size can be estimated. The time when the FWD measurement should be conducted is specified to minimize the influence of a vertical variation of temperature in a concrete slab.
