摘要
根据沥青路面的破坏机理,分析了影响沥青路面疲劳寿命的因素,对沥青混合料疲劳寿命的预估方法——Cooper-Pell法、能量法、美国沥青学会法和CRR法进行了介绍,并指出充分了解沥青路面疲劳性能与建立相应的评价标准对沥青路面的使用具有重要意义。
According to the failure mechanism of asphalt pavement, this paper analyzed the factors influence of fatigue life of asphalt pavement, introduced the prediction method Cooper-Pell method, energy method, American asphalt association method and CRR method of asphalt mixture fatigue life, and pointed out that fully understanding the fatigue performance of asphalt pavement and establishing corresponding evaluation stand- ard had vital significance to the use of asphalt pavement.
