摘要

为了研究排水性沥青路面的横向空隙分布特性,对宁杭高速公路排水路面某横断面不同位置的芯样进行了切割处理,采用数字图像处理技术,分析了排水性沥青混凝土在不同界面的空隙组成.研究结果表明:降雨过程中,污染物的沉淀是排水路面空隙堵塞的主要原因,深截面堵塞较浅截面更为严重,且沿着水流方向,空隙的堵塞越来越严重;内侧车道的轮迹带浅界面的空隙堵塞比小于非轮迹带;由于车辆荷载的作用,导致排水路面在使用过程中出现了二次压密,轮迹带和重车道空隙率相对较小;采用设置双层排水面层、设计内低外高横坡的方案可以缓解排水路面的空隙堵塞病害.

Abstract

To research the horizontal voids distribution characteristics of porous asphalt pavement, the core samples from one cross section of Ninghang highway were incised, and the digital image processing technology was used to analysis the void characteristics at different sections of the core samples. The results show that the main reason of clogging in porous asphalt pavement comes from subsidence of runoff suspended particles during rainfall. The deep section clogging is more serious than that in the shallow section, and the outside section clogging becomes more serious along the flow direction. The ratio of void clogging in shallow section of inside wheel track is less than that of nonwheel track. During the usage of porous asphalt pavement, the effect of wheel loads leads to further compaction, and the voids of wheel track and heavy lane are relatively small. Double porous asphalt layers and inside low lateral high slope can slow down the clogging of porous asphalt pavement.
