Pavement structure and construction method thereof
The invention discloses a pavement structure which comprises a water stabilizing layer, a gravel sealing layer, a lower surface layer and an upper surface layer which are sequentially distributed frombottom to top, and is characterized in that the water stabilizing layer is provided with a groove extending transversely, and the groove is filled with an elastic sealing strip; geotextile covers thegroove and the elastic sealing strip, the width of the geotextile in the longitudinal direction is 0.5-2 m, and the geotextile is arranged between the water stabilizing layer and the gravel sealing layer; a geogrid is further arranged between the lower face layer and the upper face layer, the width of the geogrid in the longitudinal direction is 1-3m, and the geogrid is located above the geotextile. The invention further relates to a construction method of the pavement structure. According to the pavement structure, the construction period is shortened, part of labor cost and mechanical retention cost are saved, and irregular cracks of the water stable layer are greatly reduced. And meanwhile, no reflection crack is formed in the asphalt pavement above the groove, so that the effect is better, and the popularization value is higher.
本发明公开了一种路面结构，其包括从下到上依次分布的水稳层、碎石封层、下面层和上面层，其特征在于，所述水稳层设置有横向延伸的凹槽，所述凹槽内填充有弹性密封条；所述凹槽和所述弹性密封条的上方覆盖有土工布，所述土工布在纵向上的宽度为0.5‑2m，所述土工布在所述水稳层和碎石封层之间；所述下面层和所述上面层之间还设置有土工格栅，所述土工格栅在纵向上的宽度为1‑3m，所述土工格栅位于所述土工布的上方。本发明还涉及该路面结构的施工方法。本发明缩短了施工周期，节省了部分人工费用与机械滞留费用，水稳层本身不规则裂缝也大量减少。同时，凹槽处上方沥青路面处并无反射裂缝，效果较佳，具备较大推广价值。
