透水性沥青混凝土面层在城市道路中的应用

Application of Penetration Bituminous Concrete Surface Course in Urban Roads

通过分析透水性沥青混凝土路面的特性及优点,结合工程应用实例对透水性沥青混合料的材料选择、配合比、施工工艺等方面进行尝试与探讨。实践证明,在城市道路中采用透水性沥青面层技术可行、设计简易、施工方便,且工程费用增加不大,在我国南方多雨地区有较强的现实意义和推广价值。

Through analyzing characteristics and advantage of penetration bituminous concrete pavement,in combination with project application example the paper attempts and approaches in the aspects such as the selection,mixture ratio and construction process etc.of penetration bituminous mixture material.The practice ensures that to adopt penetration bituminous surface course technology in urban roads is feasible with simply design and easy construction and not great engineering cost.So it has stronger practical or immediate significance as well as value for spreading in abundant rainy area in the South in China.
