路基是高速公路的基础,它是按照路线位置和一定的技术要求修筑的作为路面基础的带状构造物。路基是一种土木机构,所以它经常受到自然灾害的侵袭,因此路基必须具有足够的坚固性、稳定性和耐久性,路基质量的好坏关乎车辆通行的安全,也就是关乎人们群众的生命安全,因此必须保证公路路基的质量问题。在施工过程中,高速公路路基的施工过程比较简单,但是公路路基压实的质量控制就比较艰难,所以要严格认真的进行高速公路的路基压实,这是施工人员的责任。
Subgrade is the basis of expressway. It is a belt-shaped structure that is built on the basis of route location and certain technical requirements. Subgrade is a kind of civil organization, so it is often affected by natural disasters, so the subgrade must have enough robustness, stability and durability. The quality of the subgrade is related to the safety of vehicles, which is also related to people’s life safety Therefore, we must ensure the quality of highway subgrade. During the construction process, the construction process of expressway subgrade is relatively simple, but the quality control of highway subgrade compaction is rather difficult. Therefore, it is the responsibility of construction workers to strictly comprehend subgrade of expressway.
