摘要
针对AC-13沥青混合料进行了不同试验条件下的疲劳试验;分析了每次加载下的耗散能与荷载作用次数之间的关系;利用数理统计的方法研究了试验条件对总累积耗散能与疲劳寿命的影响。结果表明:总累积耗散能与疲劳寿命之间的关系与荷载作用模式有关,与试验温度及加载频率无关。
By carrying out fatigue test under different conditions of AC-13 asphalt mixture,the relation between dissipated energy per load and loading times was analyzed.The impact of test conditions on accumulated dissipated energy and fatigue life was studied through statistical methods.The result indicated that the relationship between accumulated dissipated energy and fatigue life was relevant to load mode while it had nothing to do with test temperature and loading frequency.
