摘要：	Rational evaluation of the pavement condition depends on the availability of insitu material properties of pavement layers. These data are crucial for a correct evaluation of the pavement structural capacity and its remaining service life. The most acceptable nondestructive testing technique for pavement structural capacity evaluation is the Falling Weight Deflectometer test (FWD). The FWD test results are influenced by loading, climate, and pavement condition. Alternatively, acoustic testing techniques that are based on the mechanism of stress wave propagation in structural materials have been applied for the evaluation of material properties. The Spectral Analysis of Surface Waves (SASW) is typically used for the nondestructive moduli profiling of pavements and soil sites. In this study the development of a combined dynamic and acoustic nondestructive testing technique for the evaluation of pavement layers moduli is explored.
