Through indoor experiments, the performance of recovered asphalt and the aggregate gradation in reclaimed asphalt pavement(RAP) were determined. Programming solution and Marshall test were applied to determine the mix proportion and new asphalt content of different types of hot recycled asphalt mixture(AC 13 and AC 16) from central mixing plant. Additionally, mechanical properties were verified by wheel tracking test, freeze thaw split test and low temperature bending test of small beam. Splitting strength and compression rebound modulus of AC 16 were determined at different temperatures, different RAP contents(by mass), before and after repeat aging as well as before and after the addition of regeneration. The indirect tensile fatigue test was carried out by universal testing machine(UTM). The results show that with the raise of RAP contents，dynamic stability enhances, residual strength ratio of single freeze thaw cycle increases slightly but rapid decays repeatedly, crack resistance at low temperature diminishes. Compression rebound modulus rises linearly, but splitting strength shows different rules under different parameters, and fatigue life and sensitivity to stress are decreased. Finally, the laboratory test results above are verified by the road test.
