Large-gradient municipal road asphalt pavement construction method
The invention belongs to the technical field of road construction, and particularly relates to a large-gradient municipal road asphalt pavement construction method which comprises the following working procedures: pavement pretreatment; cement stabilized macadam is laid on the upper layer of the pavement to be constructed to serve as a subbase layer, and after subbase layer construction is completed, cement stabilized macadam is laid on the subbase layer; curb stone construction is carried out; construction of a steel wire mesh: spreading permeable oil on the surface of the base layer, building the steel wire mesh, and fixing the steel wire mesh on the roadbed in a suspended manner by adopting U-shaped nails; construction of an asphalt pavement layer: spraying a lower sealing layer after spraying prime coat asphalt oil, wherein the steel wire mesh is positioned in the lower sealing layer; a lower surface layer is laid on the surface of the lower sealing layer by adopting coarse grain type asphalt concrete, modified emulsified asphalt tack coat oil is sprayed on the surface of the lower surface layer, and an upper surface layer made of SBS fine grain type asphalt concrete is laid on the surface of the lower surface layer; the steel wire mesh is built in the asphalt pavement layer, and the steel wire mesh and the lower sealing layer asphalt form a reinforcing layer, so that the strength and the quality of the formed asphalt pavement layer are improved.
本发明属于道路施工技术领域，具体涉及一种大坡度市政道路沥青路面施工方法，包括以下工序：路面预处理；基层施工：在待施工路面上层铺设水泥稳定碎石作为底基层，底基层施工完毕后，在底基层上铺设水泥稳定碎石；路缘石施工；钢丝网片施工：在基层表面洒布透层油，搭建钢丝网片，钢丝网片采用U型钉悬空固定于路基上；沥青路面层施工：喷洒透层沥青油后喷洒下封层，钢丝网片位于下封层内；在下封层表面采用粗粒式沥青混凝土铺设下面层，在下面层表面洒布改性乳化沥青粘层油，在下面层表面铺设SBS细粒式沥青混凝土的上面层；通过在沥青路面层中搭建钢丝网片，钢丝网片和下封层沥青形成加强层，提高了成型沥青路面层强度和质量。
