Fatigue is one of criterions in asphalt concrete pavement design, failure of asphalt concretefatigue has correlation with the magnitude of tensile strain of asphalt layer bottom.
疲劳是沥青路面设计标准之一，沥青混凝土的疲劳失效与沥青层底拉应变值的大小相关。

At the same time the conclusion that the method of calculating the characteristic value of concretefatigue strength using fatigue life agrees to that using initial strength is presented.
分析得到疲劳寿命概率分析方法和初始强度概率分析方法计算疲劳强度标准值具有一致性；

On this basis, the fatigue reliability of the reinforced concrete bridge was analyzed.
