| 摘 要： | 水损坏病害是高速公路沥青路面常见病害之一，其中雨水通过中央分隔带渗透至路面结构是引起水损坏的重要原因。建立高速公路沥青路面中央分隔带雨水渗流模型，模拟了不同降雨强度和不同时间下中央分隔带及路面结构中雨水渗流状况，分析中央分隔带雨水渗流影响深度和广度，提出了中央分隔带排水设计方案。结果表明，中央分隔带雨水渗流集中区域横向位于内侧行车道，深度方向主要位于面层至底基层范围内。

Research on Rainwater Permeability Rule in Median Divider of Highway Asphalt Pavement Structure Based on Porous Media Theory |
| |
| Abstract: | Water damage is one of the common diseases existing in highway asphalt pavement. The permeation of rainwater to the pavement structure through the median divider is the key cause for the water damage. To establish a model for permeation of rainwater to the highway pavement structure through the median divider, the permeation of rainwater to the pavement structure through the median divider is simulated at different rainfall intensities and different time to analyze the impact of permeation of rainwater through the median divider and provide a water drain scheme for the median divider. The results demonstrate that the centralized rainwater permeation area of the median divider crosswise is located in the inner traffic lane on the transverse and between the surface course and subbase course in the depth direction. |
