摘要
采用沥青稳定碎石排水基层(ATPB)和级配碎石做沥青面层和半刚性基层之间的过渡层,形成倒装路面结构,分别在四川省高速公路工程中应用,较为实际地分析了倒装结构在抗沥青路面反射裂缝中的作用。结果表明,相对对比路段,两种倒装结构沥青路面抗反射裂缝性能显著,级配碎石的倒装结构在中、轻交通的道路上采用较好,ATPB倒装结构更适用于交通量较大的路面。
Asphalt stabilized macadam drainage base(ATPB)and Graded Macadam are used as the transition layer between asphalt surface and semi-rigid base respectively to form inverted pavement structure,which is applied in expressway engineering in Sichuan Province.The results show that,the two kinds of inverted structure asphalt pavement have better bearing capacity and anti-rutting performancethan the contrast section,andthe anti-reflective crack performance is significant.The inverted structure of Graded Macadam is better used in medium and light traffic roads.The ATPB inverted structure is more suitable for roads with large traffic volume.
