On compaction construction technology of subgrade and pavement in Highway Engineering

Abstract

driven by the rapid development of society, the number of highway engineering is increasing, and has achieved remarkable results in the development. Especially in recent years, our country pays more and more attention to infrastructure construction, but at this stage, there are still many construction enterprises in the construction process did not strictly according to the corresponding standard construction, in which the subgrade and pavement compaction construction is a very key link in highway engineering construction, which directly affects the quality and service life of the whole highway engineering.During the process of urban trunk, fast road excavation, you need to dig 0 to 30 cm downwards, and its compaction cannot be less than 95%. In a filling of 0 to 80 cm, the compaction is equally less than 95%. The author explores and analyzes the important significance of highway engineering subgrade and pavement compaction construction technology and the main factors affecting highway engineering subgrade and pavement compaction construction, and puts forward the application measures of highway engineering subgrade and pavement compaction construction technology, hoping to help the smooth construction of highway engineering subgrade and pavement compaction.
