Measures for the Optimization of Subgrade and Pavement Design in the Reconstruction and Expansion of Highways

Abstract

In comparison to the construction of modern highway engineering, several of China’s early pavement construction concerns, such as pavement collapse, are rather clear. Limited by historical and technical factors, the subgrade and pavement design for highways lacks scientificity, thus inducing potential safety problems in the operation. In order to comprehensively improve the subgrade and pavement design as well as ensure the quality and safety of highway engineering projects, this paper takes the reconstructed and expanded highway projects as research subjects and focuses on proposing optimization measures for the subgrade and pavement design of reconstructed and expanded highways, so as to provide adequate reference.
