Mechanical Analysis and Asphalt Layer Subdivision of Long Life Asphalt Pavement Structures

Abstract

Based on asphalt pavement design theory and criterions in China, and referring to successful long life asphalt pavement structures in foreign countries, the stress-strain data in different depths were calculated by using B1SAR3.0 program taking different structures and materials such as structure thickness, modulus and Poisson ratio, etc. The data analysis results show that (1) there is a high compound stress area in
