Abstract: Based on the regional climate change in central China (Wuhan), a three-dimensional temperature analysis finite element model of asphalt pavement was established, and the summer temperature effect of asphalt pavement was studied, and the representative daily cycle temperature field variation curve of asphalt pavement in summer was obtained. Combined with laboratory tests and references, the effect of temperature on the elastic modulus and Poissons ratio of asphalt mixture was analyzed, and the influence of regional climate change on the permanent deformation of asphalt pavement was calculated. The results show that there is a negative correlation between the temperature change rate of asphalt pavement and the depth of pavement structure. The regional climate change mainly affects the asphalt surface area, and will significantly reduce the elastic modulus of asphalt pavement material (about 30%) in summer, has little impact on Poisson's ratio. Regional climate change will increase the permanent deformation of asphalt pavement by more than 30% in future, which will aggravate the damage of asphalt pavement. The study can provide some reference for the influence of global climate change on asphalt pavement design and service performance evolution.

摘要： 基于华中(武汉)区域气候变化，建立了沥青路面三维温度分析有限元模型，对沥青路面夏季温度效应进行了研究，得出了沥青路面夏季代表性日周期温度场变化曲线。结合室内试验和参考文献，分析温度对沥青混合料弹性模量和泊松比的影响，并计算了区域气候变化对沥青路面永久变形量的影响。结果表明：沥青路面的温度变化速率和路面结构深度存在负相关关系，区域气候变化主要影响沥青面层区域，且会明显地降低夏季沥青路面材料的弹性模量(30%左右)，但对泊松比影响较小。未来区域气候变化会增加沥青路面永久变形30%以上，加剧沥青路面的破坏。可为全球气候变化对沥青路面设计的影响及服役性能演变提供一定的借鉴与参考。
