In order to truthfully reveal the stiffness decay regularity of asphalt mixture，the nonlinear fatigue damage evolution model of asphalt mixture based on accelerated loading test are established accordingly mixture，first，the accelerated loading test is conducted on the formed standard asphalt mixture specimens by accelerated loading test system，and the moduli of resilience of the asphalt mixture under different loading times are tested by materials testing system，Based on the basic theory of damage mechanics, the decay of modulus is defined as the damage variable, and the stiffness decay equation and the nonlinear fatigue damage evolution model .The results of the nonlinear fatigue damage evolution model takes into account the loading history, which more faithfully reflects the fatigue damage of asphalt mixtures under cyclic loading; the stiffness decay regularity under the condition of accelerated loading test is different from that of the common fatigue loading methods in the third stage during fatigue failure process，the decay rate increases at first and then decreases．
