The sponge city concept emphasizes regulating stormwater runoff through natural means. As one of its core technologies, permeable asphalt pavement plays a crucial role in runoff control. This study aims to evaluate the efficiency of permeable asphalt pavement in urban stormwater runoff control and analyze its performance under different rainfall conditions. By combining experiments and simulations, this paper discusses the water permeability, infiltration capacity of permeable asphalt, and its role in the urban water environment. It assesses the effects of permeable asphalt on reducing surface runoff, improving stormwater utilization efficiency, and alleviating urban waterlogging. The research results show that permeable asphalt can not only effectively reduce stormwater runoff but also alleviate the pressure on urban drainage systems, providing an effective approach for sponge city construction.
