Study on the Fatigue Performance of Rubber Asphalt Stress Absorbing Layer Based on Indoor Test

Junqi Gao

Abstract

Through fatigue test of beam specimen under strain control,the fatigue performance of rubber asphalt stress absorbing layer is study.besides,the fatigue test of other four immediate layer is made.The result shows rubber asphalt stress absorbing layer has good fatigue performance.It can better bear alternating load from vehicle and temperature and elongate life period of pavement.
