通过铺筑7 cm AC13面层＋39 cm级配碎石基层，9 cm AC13面层＋39 cm级配碎石基层2种路面结构作为实验路，进行加速加载实验，实验过程中对面层层底应变进行了监测；通过引入当量加载次数的概念，对不同变应变条件下的加载次数进行转化，建立了2种路面结构的疲劳方程等式，通过求解得到沥青路面疲劳方程。本所建立的疲劳方程是在整体路面上进行加速加载实验所得，研究结果更加符合实际情况。

Two kinds of indoor testing roads are constructed:7cm AC13 surface and 39 cm graded grav‐el base;9cm AC13 surface and 39 cm graded gravel base .Accelerated pavement testing is carried on and during the testing process ,the data of strain ,temperature and loading times are gained .After the concept of equivalent loading times is introduced ,the loading times under different strain are conver‐ted the standard loading times ,the two pavement fatigue equation are established ,and then asphalt fatigue prediction model is established by solving the tw o equations .T he results are established on the bases of real pavement ,so it is more accurate than others .
