摘要
针对京港澳高速公路湖北段半刚性基层沥青路面水损坏严重的现象,在分析比较了半刚性基层和柔性基层优缺点的基础上,在实验室采用马歇尔试验设计方法确定了ATPB-25的级配和最佳沥青用量,并对其排水性和水稳定性进行了试验研究,认为级配合理的沥青稳定碎石排水基层具有较高的强度和一定的水稳定性,采用沥青稳定碎石排水基层是合理的。
To solve road sections of Bei the serious water damage problem of the semi-rigid base AC pavement in several jing-HongKong-Macou expressway in Hubei province, Based on the analysis and comparison of the advantages and disadvantages of the semi-rigid base and the flexible, the gradation of ATPB-25 and the best amount of asphalt are determined by using Marshall method, and its properties such as drainage property and good water stability are tested and studied. It is considered that the asphalt treated permeable base （ATPB-25） has high strength and good water stability and it is reasonable to use the asphalt treated permeable has.
