With the development of the asphalt pavement mechanistic-empirical design and analysis methods,the research of pavement material parameters is becoming more and more significant. In this investigation,the MTS system was used to do the dynamic modulus test for ATPB-25 and ATPB-30,which are both asphalt treated permeable base( ATPB) mixture. During the test,different measuring temperatures and loading frequencies are set according to the temperature environment of the asphalt mixtures. Then,based on the test results,a full time-domain dynamic modulus master curve and corresponding master curve equation of the asphalt mixture are created. By these experiments,high-quality parameters for the optimization design and performance analysis of asphalt pavement structure with ATPB can be established. These studies are of great significance in extending the service life of the asphalt pavement. asphalt mixture; dynamic modulus; master curve; pavement mechanics; empirical design
