随着我国经济发展,原有的旧公路难以承载急剧增加的车流。旧路改建加宽是提升原有公路通行能力的主要方法之一。路基质量是保持路面稳定的基本条件。为了保证旧路改建时路基的质量,施工前要确定路面加宽方式,清理施工现场,检查现场地形地势;施工时要控制填料质量,做好表层处理,做好土质台阶,做好软基处理、渗水路堤处理、边坡处理,并给予路基足够的沉降固化时间。
With the economic development in our country, the existing old roads are difficult to carry the rapidly increasing traffic flow. Widening of old roads is one of the main ways to enhance the capacity of existing roads. Subgrade quality is the basic condition for keeping the road stable. In order to ensure the quality of subgrade when the old road is rebuilt, it is necessary to determine ways of widening the pavement before construction, to clean the construction site and to check the topography of the site; to control the quality of the packing during construction, to finish the surface treatment, to do the soil step, , Infiltration embankment treatment, slope treatment, and to give sufficient subgrade settlement solidification time.
