The paper tested conventional and Srtategic Highway Research Program(SHRP) index performance of TPE and SBS modified asphalt. The test results show that TPE modified asphalt can effectively improve the high temperature performance, water stability and low temperature performance of asphalt mixture. Although the performance of TPE modified asphalt is inferior to SBS modified asphalt, the three major indexes all meet the specification requirements. The overall road performance of TPE modified asphalt mixture meets the technical requirements of modified asphalt, and even from the rut test and SPT test results, the high-temperature anti rut performance is higher than SBS asphalt mixture.
