Advances in Constructional Engineering

As a crucial solution to urban water environment issues, the sponge city concept emphasizes the natural circulation and rational utilization of water. As a core component of this concept, permeable pavement systems have been widely applied in urban construction. Aiming at the frost-thaw damage problem faced by permeable pavement systems in cold regions, this paper conducts experimental research to improve the frost-thaw resistance of permeable pavement materials, so as to enhance their durability and stability under extreme climatic conditions. Through modifying material proportions and enhancing technologies, the experiment finds that appropriate improvement measures can effectively enhance the frost-thaw damage resistance of permeable pavements, thereby prolonging their service life and optimizing the construction effects of sponge cities. The research results provide a theoretical basis and practical guidance for the application of permeable pavements in cold regions.
