Research on Propagation and Fatigue Life of Asphalt Pavement Surface Crack

Abstract

Focusing on the severity of asphalt pavement surface crack, a finite element analysis model of 20-node isoparametric elements was established with the commerce FEM software ABAQUS based on fracture mechanics theory. The surface crack of pavement was numerical analyzed and the crack propagation life was evaluated by Paris formula. In the course of surface crack propagation the change of the stress intensity factor (
