Prediction of Fatigue Cracking Life of Reinforced Asphalt Concrete Pavements

摘要

Based on fatigue fracture mechanics theory, the analysis is carried out for the fatigue cracking of reinforcing asphalt concrete pavements under traffic loads by using FEM. By comparing, it is pointed out that the bonding condition between reinforcement and half-rigid base course and the characteristics of reinforcement influence the fatigue cracking life of reinforced asphalt concrete pavements apparently. And it is suggested to the demands of the interfacial parameter, stiffness modulus and strength of reinforcement.
