RESPONSE OF PAVEMENT SYSTEMS TO DYNAMIC LOADS IMPOSED BY NONDESTRUCTIVE TESTS

Dynamic nondestructive testing of pavements can be grouped into two categories: (a) deflection basin tests and (b) wave propagation tests. Among the deflection basin tests, the Falling Weight Deflectometer (FWD) test has seen the most widespread use. Of the wave propagation tests, the Spectral Analysis of Surface Waves (SASW) test can be used with or serve as an alternative to deflection basin tests. The theoretical formulation used to analyze the dynamic response of pavement systems to dynamic loads imposed by such nondestructive testing techniques is presented. Analytical studies of the dynamic response of two generalized pavement systems (a flexible one and a rigid one) to the FWD and SASW tests were carried out. The results indicate that dynamic deflection basins due to the FWD load can be substantially different from those obtained under static conditions. The study shows that when complete time histories of FWD deflections are stored, the additional information can provide substantial insight into the properties of the pavement system and can significantly facilitate the inversion process. The dispersion curves obtained with the SASW test are very sensitive to the stiffness of the surface and subgrade layers but, unfortunately, are relatively insensitive to the properties of the base layer. These results are true even when bedrock is present at shallow depths.
