Dynamic Response Analysis of Asphalt Pavement Based on Transversely Isotropic Subgrade under Different Speeds

Abstract

Considering the typical semi-rigid pavement structure, combined with our existing asphalt pavement structural design specification indicators and pavement analysis evaluation indexes, this paper discussed the changing of surface deflection and the tensile stress of the bottom of asphalt pavement graded aggregate base on load axle center under subgrade transversely isotropic, different speeds and non-uniform dynamic load ,when the vehicles running to the central road of model which has a good guide for low speed controlling and service life extension of the road.
