| 摘 要： | 为了确定水温综合作用对路面疲劳破坏的影响,采用单轴无反向应力轴向压缩疲劳试验,对比研究沥青路面经受水温综合作用后及常规条件下的疲劳寿命。根据试验结果分析了两种条件下的疲劳方程及疲劳特征系数,研究了水温作用下及常规条件下疲劳系数的变化规律及原因。

| Abstract: | In order to determine the influence of water-temperature effect on fatigue failure of asphalt pavement, the uniaxial compression fatigue test with no reverse stress was carried out to conduct the comparison of fatigue life influenced by water-temperature effect and under general condition.The fatigue equation and fatigue feature coefficient were analyzed in terms of the test results,and the varying laws for both conditions were studied. |

| Keywords: | fatigue life water-temperature effect general condition stiffness modulus |
