Construction method for urban and rural arterial highways
The invention provides a construction method for urban and rural arterial highways. The construction method comprises the steps of determining a field working boundary, surveying and setting out and cleaning a field; matching an excavator and a dump truck and a carry-scraper to transport earth and stone to form a roadbed, and rolling the roadbed; paving a soil material in the roadbed; paving a broken stone hardcore on the soil material layer; spraying prime coat oil by adopting an asphalt spraying machine; preparing an asphalt mixture; and paving an asphalt concrete surface layer and rolling. According to the technical scheme, the roadbed is rolled, the soil material and the broken stone hardcore are filled in sequence, and then the asphalt concrete surface layer is paved, so that differential settlement generated on the two sides is reduced, the overall stability of the road and the smoothness of the road surface are guaranteed, and the driving comfort of vehicles on the road is improved; and after the asphalt mixture is laid, repeated rolling is performed, so that the viscosity, the wear resistance and the water resistance of the road are improved, and the construction quality is effectively improved.
本发明提供一种城乡干线公路施工方法，包括以下步骤：确定现场工作界线、测量放样和清理场地；采用挖掘机配合自卸汽车和铲运机运输土石方形成路床并对路床进行碾压；在路床内摊铺土料；在土料层上摊铺碎石垫层；再采用沥青洒布机喷洒透层油；制备沥青混和料；摊铺沥青混凝土面层并进行碾压。采用本发明的技术方案，通过对路床进行碾压，再通过先后填筑土料和碎石垫层后再摊铺沥青混凝土面层，减少了两侧产生的不均匀沉降，保证公路的整体稳定性和路面平顺，提高道路车辆行驶的舒适性，铺设沥青混合料后又进行了反复碾压，提高了道路的粘黏性、耐磨性以及防水性，有效提升了施工质量。
