[Purposes]The paper aims to explore the problem of the weak interface between the layers of traditional pavement composite structure. [Methods]The TS-16 asphalt mixture different from the AC-16 asphalt mixture gradation range was designed. Aiming at the TS-16, AC-16 asphalt mixture and traditional double-layer structure of asphalt pavement, the compaction performance test, road performance test and direct shear test under different loading rates and temperatures were carried out. [Findings]The compacting performance of the four asphalt mixtures is in the order of TS-16A>TS-16B>TS-16C>AC-16, and the TS-16Aasphaltmixturehasthebesthigh-temperatureperformance, low-temperaturecrack resistance,water stability and fatigue resistance. [Conclusions]The direct shear strength of single-layer asphalt mixtureis much higher than that of double-layer structure,and the more easily compacted the asphalt mixture, the better its shear strength.
