Research on Construction Technology of Subgrade and Pavement in Urban Road and Bridge Engineering

Abstract

The construction of urban roads and bridges is related to people’s livelihood and social and economic development. In the implementation of urban road and bridge engineering, common problems include soft soil subgrade, slope soil base, transition section settlement or cracking and so on. In order to ensure the quality and safety of urban roads and bridges, it is necessary to analyze the common engineering problems and put forward the corresponding construction technology and supervision strategies to form the roadbed and pavement construction technology system, so as to promote the high-quality implementation of urban roads and bridges in China.
