Abstract
Abstract: With the overall progress and development of the market economy, the construction of sponge city has received extensive attention. In order to further create an environment more suitable for people's lives, relevant departments should actively apply diversified materials and integrate material supervision mechanisms in the construction of sponge city roads. Construct a systematic road restraint mechanism and management system to ensure that the characteristics of the surface ecological environment can be fundamentally improved. This paper briefly analyzes the pavement structure design mechanism in combination with the engineering project. The application path of the fine-grained drainage asphalt surface layer in the sponge city road is explained from the mix ratio of the mixture and the construction process. It is for reference only.
