In order to eliminate fatigue crack， the fatigue performance of cement stabilized gravel with different waste rubber powder content was studied by three-point loading method. Fatigue mechanism of cement stabilized gravel with waste rubber powder was characterized by three-point bending beam method. The results show that fatigue lives of cement stabilized gravels with rubber powder content of 10， 20 kg/m³ are better than that of reference cement stabilized gravel. Cracking toughnesses of cement stabilized gravels with rubber powder content of 10， 20 kg/m³ are 1.49， 2.58 times that of reference respectively. And instability toughnesses of cement stabilized gravels with rubber powder content of 10， 20 kg/m³ are 1.30， 2.21 times that of reference. So fatigue resistances of cement stabilized gravels with rubber powder content of 10， 20 kg/m³ are remarkable because that its fracture energy is large. Fatigue performance of cement stabilized gravel with rubber powder content of 30 kg/m³ does not increase because that its bending tensile strength is low with increasing rubber powder content.
