| Abstract: | Fatigue damage mechanism caused by cyclic loading vehicle was analyzed;a method was proposed to evaluate OGFC asphalt fatigue performance;corresponding tests were conducted to study the response of OGFC fatigue performance impacted by four factors-gradation,asphalt type,oil-stone ratio and loading level.The results demonstrated that four different factors contribute to fatigue life should be gradation > loading level >asphalt varieties > oil-stone ratio according to their importance. |

| Keywords: | OGFC mixture anti-fatigue performance gradation oil-stone ratio loading level |
