摘　　要：为分析不同条件下AC-13沥青混合料疲劳寿命,文中主要就荷载次数与试件单次加载下产生耗散能之间的关系进行探析,并对不同试验条件下试件疲劳寿命与耗散能累积量之间的关联性展开研究。结果表明,AC-13沥青混合料疲劳寿命与试验加载频率及环境温度之间没有明显关系,但与荷载的作用模式之间存在一定关联。In order to analyze the fatigue life of AC-13 asphalt mixture under different conditions,the paper mainly analyzes the relationship between the number of loads and the dissipated energy generated under single loading of specimens,and studies the relationship between the fatigue life of specimens and the cumulative amount of dissipated energy under different experimental conditions.The results show that the fatigue life of AC-13 asphalt mixture has no obvious relationship with experimental loading frequency and ambient temperature,but has a certain relationship with the mode of action of load.
