Advances in Constructional Engineering

With the continuous advancement of urbanization, the demand for pavement materials in southern China's rainy regions has been steadily increasing. Permeable concrete, renowned for its excellent water permeability and eco-friendly properties, has become a preferred choice for pedestrian walkway construction. This study analyzes the durability of permeable concrete in humid southern regions, investigating its long-term performance under high-humidity and heavy rainfall conditions. The findings indicate that the durability of permeable concrete is influenced by multiple factors including climatic conditions, construction quality, and material selection. By optimizing material mix ratios and construction techniques, significant improvements can be achieved in the long-term durability of permeable concrete in rainy areas, ensuring its widespread application in urban infrastructure.
