摘　　要：透水性沥青路面由于具有迅速排水、抗滑、降低雨天水雾、减少雨后反光、降低噪声等许多优点,而成为道路路面发展的重要方向。讨论了透水性沥青路面在铺装结构上的特点,并基于日本使用的透水性沥青路面结构特征,通过数值模拟,对比分析了降雨条件下透水性沥青路面与普通密级配沥青路面的水头分布变化情况,研究了透水性沥青路面在强降雨期的排水性能。Permeable asphalt pavement becomes the important trend of pavement development due to its many advantages such as rapid drainage,skid resistance,rain mist reduction,reflection reduction and noise reduction.In this paper,the paving characteristics of permeable asphalt pavement are discussed.Based on the structural characteristics of permeable asphalt pavement applied in Japan,water head distribution for permeable asphalt pavement and common dense-graded asphalt pavement under rainfall are separately analyzed through numerical simulation,and thus the drainage ability of permeable asphalt pavement under strong rainfall is studied.
