沥青稳定碎石透水基层试验路施工与评价

Construction & Evaluation of Porous ATPB Testing Road

设置透水基层可以减轻路面结构的水损害已成为共识,但是对于透水基层的结构构造形式和施工技术尚缺乏系统研究。通过依托具体工程实践,提出了适应低矮软土路基地区的透水基层结构和构造形式,进而结合试验路段的施工控制规范了透水基层的施工工艺,最后在现场检测试验的基础上进行了透水基层试验段的路用性能和经济性的分析与评价,相关研究成果可作为透水基层试验路推广普及的重要依据。

Adding Asphalt Treated Porous Base(ATPB)beneath the compacted asphalt mixture is an effective method to reduce water failure,but its pavement structure type and construction technology are still short of research.Based on testing road project,this pa- per proposed one detailed structure with permeable base layer suitable for low soft soil roadbed.ATPB construction Technology is al- so standardized in the process of testing road construction.The road performance and economic are evaluated systematically.Re- search conclusion can be referred by further application.
