Permeable pavement, also known as ecological permeable pavement, pervious concrete, or no-fines concrete,^[1]is made by uniformly mixing aggregate gravel, cementitious materials, additives, cement, water, etc., and then paving it into a road surface. It possesses the strength and durability of concrete, meeting the mechanical performance, functional requirements, and service life demands of structures. It harmonizes with the natural environment, reduces the burden on the Earth and ecological systems, and enables the recycling of resources. With excellent functional performance, it helps create a mild, comfortable, and convenient living environment for humanity.

Permeable pavement allows rainwater to quickly infiltrate the surface, effectively replenishing groundwater, mitigating the urban heat island effect, and protecting urban natural water systems from damage, offering significant environmental value. At the same time, it addresses the common issue of water accumulation on conventional road surfaces, improving walking safety and comfort, which is also meaningful for enhancing the living environment.
