新时期,随着我国经济实力不断增强和科技力量不断扩大,我国高速公路的建设要求越来越高,高速公路的建设也加快了我国经济发展的速度。其中高速公路路基的质量直接影响着整条高速公路的安全运行,因此达到高速公路路基的高标准质量是当前高速公路建设的重要课题。 In the new era, with the continuous enhancement of China’s economic strength and continuous expansion of science and technology, the demand for the construction of expressways in our country is getting higher and higher. The construction of expressways has also accelerated the pace of economic development in our country.
