公路路基承受着本身土体的自重和路面结构的重量,同时还承受由路面传递下来的行车荷载,因此路基是公路的承重主体。它的施工质量对公路使用寿命、路面平整度、承载能力等有着重要的影响。随着车辆行车速度与载重量的增加,公路路基设计标准也在不断提高,如何针对公路设计标准的提高开展路基施工质量控制成为了现代公路施工企业面临的首要问题。
Highway subgrade to bear the weight of its own soil and the weight of the pavement structure, while also under the road load transmitted by the driving load, so the subgrade is the main load-bearing highway. Its construction quality has an important influence on the service life of the road, the smoothness of the road and the carrying capacity. With the increase of vehicle speed and load, the design standards of highway subgrade are also constantly improving. How to carry out subgrade construction quality control for the improvement of highway design standards has become the primary problem faced by modern highway construction enterprises.
