DYNAMIC TEST OF ASPHALT CONCRETE AND ANALYSIS OF DYNAMIC RESPONSES ON 3D LAYERED SYSTEM USING TEST RESULTS

摘要：

Dynamic modulus (E*) is one type of modulus tested under dynamic loading used to evaluate the elastic-viscoelastic response parameters of a material.A new numerical method has been extensively applied into solving dynamic problem of the wave propagation.For the spectral analysis of the three-dimensional multi-layered pavement,wave propagation analytical method is presented to solve the problems of bounded layer system subjected to a transient load pulse.From analytical results,it proved that dynamic modulus from 5Hz-20Hz are more close to the actual dynamic response of the vehicle loads.
