摘　　要：利用传热学基本理论,建立沥青路面温度场数值预估模型,对北方地区突然降温情况下路面内部温度分布情况进行有限元计算,并对路表温度变化对沥青路面各层温度的影响进行研究。Based on basic theory of heat transfer the model for preappraising the value of temperature field on asphalt pavement is established; by finite element calculations of distribution of temperature inside the pavement under suddent temperature lowering in northern area; and influence of the variation of pavement surface temperature on temperature of all the layers of asphalt pavement is also studied.

关 键 词：沥青路面 温度梯度 温缩裂缝 有限元
