摘要
分析了车辆重复荷载引起的OGFC疲劳损害机理;设计了一种评价OGFC沥青混合料抗疲劳性能的试验方法;试验研究了级配、沥青种类、油石比以及加载水平等因素对OGFC沥青混合料疲劳寿命的响应规律。结果表明:4种因素对疲劳寿命的贡献主次顺序依次为:级配>加载水平>沥青品种>油石比。
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.
