【Abstract】High strength, stability and durability of the roadbed will be a good support system pavement structure is conducive to improving the overall strength and performance of the pavement to extend the service life of the road at the same time, can also reduce the cost of road construction and highway maintenance costs. Therefore, we must attach importance to roadbed construction, and effectively ensure the quality of roadbed construction, in order to improve the economic and social benefits of road construction to provide effective protection. Soil roadbed construction is a necessary process in road construction. Whether or not this procedure is qualified directly affects the whole project, but in practice there are many problems affecting the implementation of the project. The article is aimed at the roadbed construction method and some problems in construction Analyzed.

路基是支承路面的土构筑物,在挖方路段,路基是开挖天然地层形成的路堑;在填方路段,则是用压实的土石填筑而成的路堤。由于路基在使用过程中要承受由路面传递而来的行车荷载作用并抵御各种环境因素的影响,因此要求路基必须具有足够的强度、良好的水温稳定性和耐久性。所谓路基施工,就是以设计文件和施工技术规范为依据,以工程质量为中心,有组织、有计划的将设计图纸转化为工程实体的建筑活动。
1. 路基施工重要性
(1)路基施工的重要性,突出地表现为对工程质量的高标准要求。强度高、稳定性和耐久性良好的路基将成为路面结构的良好支承体系,有利于提高路面整体强度和使用性能,延长路面使用寿命,同时,还可以降低路面工程造价和公路养护维修费用。……
