The construction quality of stone-filled roadbed construction will directly affect the whole highway construction quality. Therefore, engineers and technicians should reasonably apply the stone-filled roadbed construction technology and ensure the standardization and scientificalness of the technology to fundamentally improve the highway construction quality in our country. Based on a highway project, this paper discusses and analyzes the application of stone-filled subgrade construction technology in highway construction, hoping to provide reference for relevant personnel.展开更多

Understand the key technology of subgrade engineering, effectively control the whole project, and quickly improve the engineering control level, so as to achieve better engineering quality. Therefore, in the construction of the highway subgrade, we should fully understand the common problems of the subgrade, grasp the structural characteristics of the subgrade, improve the construction technology, ensure the normal running of vehicles, and improve the comprehensive benefits of the highway.展开更多
