Title: Permanent deformation of high modulus asphalt concrete pavement
Abstract: In order to evaluate the high temperature performance of high modulus asphalt concrete exactly,based on the creep test data of high modulus asphalt concrete,the permanent deformations of different types of high modulus asphalt concrete pavements were predicted and the effects of material composition and vehicle speed on the permanent deformation were discussed.The results show that high modulus asphalt concrete pavement composed with 50#asphalt has larger permanent deformations than the asphalt mixture composed with 70#asphalt,and the high modulus asphalt concrete in which the special additives were added has the smallest permanent deformation.Different temperature sensitivities can cause the inconsistency of asphalt performance in ambient temperature and high temperature,and the accurate evaluation of high temperature performance of high modulus asphalt concrete can be obtained by high temperature creep model.5tabs,2figs,6refs.
