Double-layer drainage asphalt concrete pavement laying construction method
The invention provides a double-layer drainage asphalt concrete pavement laying construction method. The double-layer drainage asphalt concrete pavement laying construction method comprises the following steps: S1, a soil base layer and a stabilized macadam base layer are constructed and checked and accepted; s2, construction and acceptance check of the waterproof bonding layer, the lower surfacelayer dense graded asphalt concrete layer and the waterproof isolation layer; s3, preparing a water-permeable asphalt concrete mixture; s4, paving a middle surface layer, and rolling and compacting the middle surface layer; s5, paving the upper surface layer, and rolling and compacting the upper surface layer; and S6, pavement quality detection and acceptance. The drainage asphalt concrete provided by the invention has large pores, the high-viscosity asphalt cementing material is lost at an over-high temperature, the temperature of the mixture is reduced too quickly, and technological parameters in the mixing, transporting, paving and rolling processes of the asphalt mixture need to be strictly controlled during pavement paving construction; meanwhile, using performance indexes of the pavement are tested on site, and CT scanning is adopted to obtain internal pore characteristics and spatial distribution conditions of the core sample structure; and a reasonable construction process in the laying construction process ensures the construction quality and the use performance of the pavement.
本发明提供一种双层排水沥青混凝土路面铺设施工方法，包括以下步骤：S1，土基层和稳定碎石基层的施工并验收；S2，防水粘结层、下面层密级配沥青混凝土层及防水隔离层的施工与验收；S3，制备透水沥青混凝土混合料；S4，摊铺中面层并碾压压实；S5，摊铺上面层并碾压压实；S6，路面质量检测及验收。本发明中的排水沥青混凝土孔隙大，高粘沥青胶结料在过高温度下流失、混合料温度下降过快，在路面铺设施工时需严格控制沥青混合料的拌制、运输、摊铺和碾压过程中的工艺参数；同时，现场测试路面的使用性能指标，采用CT扫描获得芯样结构内部孔隙特征和空间分布情况；铺设施工过程中合理的施工工艺，保障了路面的施工质量和使用性能。
