| 摘 要： | 已有文献表明加载频率对于疲劳寿命的影响较大，对于沥青砼而言，其影响可能更显著，因为在低频条件下，其流变性能表现得更充分．笔者根据沥青混合料的室内低频疲劳试验，运用耗散能理论，得到了沥青混合料的低频疲劳规律．

| Abstract: | It was reported that the loading fre- quency has a remarkable influence on material's fa- tigue life. The influence on asphalt concrete fatigue life may be larger than that on ordinary materi- als because of its obvious rheological character at lower loading frequency. The fatigue rules of asphalt concrete at lower loading frequency are obtained by means of low frequency loading fatigue test at dif- ferent frequencies and temperatures. |
