摘　　要：公路路基的主要作用是承受公路结构层重量和路面荷载,是公路的重要组成部分。然而在新改建沥青路面路基顶面设计交工验收弯沉值方面,有的项目参建单位存在重视情况不够,设计值偏大等问题。为此,文章以工程案例说明从严控制路基设计交工验收弯沉值的可行性,并且通过加强路基工程施工管理,在不增加造价的前提下,可以极大减小路基交工验收弯沉值,保障工程质量,实现延长公路使用寿命的目标。The main function of highway subgrade is to bear the weight of highway structural layer and road load, which is an important part of highway. However, some project participants do not pay enough attention to it and the design value is too large in the new reconstruction of asphalt pavement subgrade top surface design and the acceptance of subgrade deflection value. In this paper, the engineering case shows that it is feasible to control the settlement value of subgrade design acceptance strictly. The settlement value of subgrade acceptance can be greatly reduced by strengthening the construction management of subgrade engineering without increasing the cost. So the project quality can be guaranteed, and the goal of prolonging the service life of highway can be achieved.
