Road construction method for cold on-site recycling of asphalt pavement
The invention relates to a road construction method for cold on-site recycling of an asphalt pavement. The method comprises the following steps: 1) construction preparation; 2) preparing a new aggregate and composite slurry according to the quality of the old asphalt pavement milling material; 3) new aggregate premixing: uniformly mixing the new aggregate with the composite slurry to obtain a wetaggregate; (3) milling and mixing: milling the old asphalt pavement according to the designed milling depth, spraying composite slurry into the milling material of the old asphalt pavement, and spreading the wet aggregate for on-site mixing and regeration; 4) initial pressure shaping: carrying out initial pressure on the regeneration working surface, and carrying out flat ground shaping; 5) composite slurry pouring: pouring the composite slurry on the initial pressure working surface, and performing vibrating, rolling and permeating; 6) rolling and molding; 7) preservation. According to the road construction method, cement, mineral powder and the like do not need to be paved on a working face, loss of raw materials is small, the utilization rate of milling materials and additional raw materials is high, and the mechanization degree of cold on-site regeneration is higher; the obtained regeneration layer is low in porosity, compact in structure, fast in early strength development and high in quality stability.
本发明涉及一种沥青路面就地冷再生的道路施工方法,包括1)施工准备;2)根据旧沥青路面铣刨料质量准备新集料和复合浆料;3)新集料预拌:将新集料与复合浆料混合均匀制得湿集料;3)铣刨拌和:按设计铣刨深度对旧沥青路面进行铣刨,向旧沥青路面铣刨料中喷洒复合浆料,并播撒湿集料就地拌和再生;4)初压整形:对再生作业面进行初压,并平地整形;5)灌浇复合浆料:在初压作业面上灌浇复合浆料,并振动碾压渗透;6)碾压成型;7)养生。该道路施工方法不必在工作面上摊铺水泥、矿粉等,原料流失损耗少,铣刨料和外加原料利用率高,就地冷再生的机械化程度更高;所得再生层孔隙率低,结构致密,早期强度发展快,质量稳定性高。
