我国高速公路沥青路面的水损坏的问题,在上世纪90年代末期引起重视。为了预防半刚性基层沥青路面的水损坏,从提高沥青混合料抗水坏性能和设置完善的排水设施两个方面进行了分析。分析结果表明,在控制空隙率、提高沥青与石料粘附性的同时,也要高度重视沥青路面结构的内部排水问题。 The problem of water damage of asphalt pavement in our country’s expressway has drawn great attention in the late 1990s. In order to prevent the water damage of semi-rigid base asphalt pavement, the paper analyzes the improvement of anti-water bad performance of asphalt mixture and the establishment of a perfect drainage facilities. The results show that, in controlling the porosity and improving the adhesion of asphalt and stone, we must attach great importance to the internal drainage of asphalt pavement structure.
