Waterproof asphalt pavement structure and construction method thereof
A waterproof asphalt pavement structure comprises an asphalt wearing surface layer, an asphalt middle-lower surface layer, a roadbed surface layer and a roadbed; a waterproof adhesive layer is arranged between the asphalt wearing surface layer and the asphalt middle-lower surface layer; a waterproof permeable sealing layer is arranged between the asphalt middle-lower surface layer and the roadbed surface layer; a drainage pipe is arranged in the roadbed surface layer, and drainage holes are formed in the circumference of the drainage pipe; and one side of the road width direction is provided with a drainage ditch, the lower side of the drainage ditch extends to the roadbed, and the side, close to the drainage ditch, of the drainage pipe is communicated with the drainage ditch. The construction method comprises the following steps: firstly, building a roadbed, then paving the roadbed surface layer on the roadbed, burying the drainage pipe in the paving process of the roadbed surface layer, cleaning waste materials in the drainage pipe, and then paving the asphalt middle-lower surface layer and the permeable sealing layer; then uniformly spraying the waterproof adhesive layer on the asphalt middle-lower surface layer, and after demulsification and evaporation of emulsified asphalt are completed, paving the asphalt wearing surface layer and properly rolling; and building the drainage ditch at a reserved position on one side of the road surface in the width direction, and enabling the drainage pipe to be communicated with the drainage ditch.
一种防水沥青路面结构，包括沥青磨耗面层、沥青中下面层、路基面层、和路基，沥青磨耗面层与沥青中下面层之间设有防水粘层，沥青中下面层与路基面层之间设置不透水的透封层，路基面层内设有排水管，排水管周向设有排水孔，路面宽度方向一侧设有排水沟，排水沟下侧延伸至路基，排水管靠近排水沟的一侧与排水沟相连通。施工方法步骤如下：首先建路基，然后在路基上铺设路基面层，路基面层铺设过程中埋设排水管，清理排水管内的废料，然后铺设沥青中下面层和透封层；然后将防水粘层均匀喷撒在沥青中下面层上，待乳化沥青的破乳和蒸发完成后，铺设沥青磨耗面层并进行适当碾压；在路面宽度方向一侧的预留位置砌筑排水沟，并且将排水管与排水沟打通。
