目前我国重型运输车辆的比重正在逐渐增加,因此,对高速公路的建设质量也有了进一步的提高,在高速公路的施工中,高速公路的路基建设是其中比较关健性的环节。所以为了加强公路建设的质量和稳定性,我们一定要注重路基施工技术的应用。本文主要阐述了高速公路路基施工的技术问题及应用。 At present, the proportion of heavy-duty transport vehicles in our country is gradually increasing. Therefore, the construction quality of expressways has been further improved. During the construction of expressways, the subgrade construction of expressways is one of the more relevant ones. Therefore, in order to strengthen the quality and stability of highway construction, we must pay attention to the application of subgrade construction technology. This paper mainly expounds the technical problems and its application of highway subgrade construction.
