高等级公路在国家发展中承担了主要的交通运输工作,并且高等级公路也是人们长途出行的必经之路。我国经济水平、工业水平、人民生活水平都在近十几年有着显著提升,这也就使得陆路货物运输量、居民汽车保有量相应地也发生了显著的提升,而这些提升造成了我国道路交通拥堵的情况。堵车问题的出现在一定程度上影响了我国经济的发展,降低了居民幸福指数。在高等级公路的扩建过程中,路基压实技术是极其重要的施工操作。这项技术对实施扩建后的高等级公路的质量,具有极其重要的作用。路基压实技术决定着扩建后高等级公路中老旧部分和扩建部分能否共同受力,这也就从根本上决定了扩建后的高等级公路的整体质量。本文就高等级公路的扩建技术,尤其是其中的路基压实技术进行了分析研究。
High-grade highways have undertaken major transportation work in national development and high-grade highways have also been the only way for people to travel long distances. China’s economic, industrial and people’s living standards have risen significantly over the past decade. This has also led to a significant increase in the amount of land cargo traffic and residents’ car ownership, which has led to the increase of road traffic in our country Congestion situation. The emergence of the traffic jam problem has, to a certain extent, affected the development of our economy and lowered the happiness index of residents. Subgrade compaction technology is an extremely important construction operation during the expansion of high-grade highways. This technology is extremely important for the quality of extended high-grade highways. The subgrade compaction technology determines whether the old part and the expanded part of the expanded high-grade highway can work together, which fundamentally determines the overall quality of the expanded high-grade highway. This paper analyzes the expansion technology of high-grade highways, especially the subgrade compaction technology.
