当高速公路远景规划中没有扩建的计划时,过厚的沥青面层对于硬路肩较为浪费,本文以硬路肩设计存在的问题为出发点,做了换填硬路肩部分材料后的弯沉值分析,为了更好的指导施工,提出了硬路肩部位施工过程的质量控制分析,并且分析了其经济效益,从而分析得出对硬路肩部位进行部分换填对于行车安全和路面使用寿命的影响,对于节约工程开支有一定帮助。 When there is no plan for expansion in highway vision planning, too thick asphalt surfacing is a waste for hard shoulders. In this paper, the problem of hard shoulders design is taken as a starting point, In order to better guide the construction, put forward the quality control analysis of the construction process of the hard shoulder and shoulder, and analyzed its economic benefits, and analyzed the impact of partially replacing the hard shoulder and shoulder on the traffic safety and the service life of the road, Project costs have some help.
