In order to achieve long-life asphalt pavement and explore the application of high modulus asphalt concrete in long-life asphalt pavement, the dynamic modulus, shear and compressive strength of high modulus asphalt mixture were studied. The results indicate that the strength of high modulus asphalt mixture has a strong time-temperature dependence and strong resistance to variable frequency loading. In addition, the high-temperature shear resistance of high modulus asphalt mixture is better than that of traditional AC （asphalt concrete）asphalt mixture, with an internal friction angle 21% smaller than that of traditional AC asphalt mixture, but a cohesive force three times higher. The mechanical response of seven different high modulus asphalt pavement structures was analyzed using finite element method, and the influence of thickness on the mechanical response of the pavement was analyzed for the four selected pavement structures. Furthermore, the functional life of high modulus asphalt pavement was predicted by rutting prediction model, with rut depth as the control index. The results show that when the structure of high modulus asphalt mixture is used for all surface layers, middle and lower layers, all mechanical indicators reach equilibrium. Compared with traditional AC structures, it can extend the road life by 326% and 118% respectively.
