Porous concrete pavement material is an eco-friendly, high-permeability material for sponge city construction, serving as a new paving method that can partially replace urban paved surfaces. It revives the urban surface, allows rainwater to seep into the ground, effectively eliminates surface water accumulation, and is a green, breathable ground material.

(1) Increase the permeable and breathable areas in cities, enhance the heat and moisture exchange between the ground surface and the air, regulate the urban climate, lower the ground surface temperature, and benefit in alleviating the urban "heat island" phenomenon.

(2) Maximize the use of rain and snowfall to increase the relative humidity of the surface, replenish the increasingly depleted groundwater resources in urban areas, and utilize permeable roadbeds as "reservoirs"; improve the living conditions for urban surface vegetation and soil microorganisms, and adjust the ecological balance.

(3) Alleviates the burden on road drainage systems during the rainy season, significantly reducing the pollution of urban water bodies from heavy rain.

(4) Absorbs noise generated by vehicle travel, creating a quiet and comfortable living and traffic environment, prevents road surface water accumulation during rain and glare at night.

(5) Prevents road积水 and night-time road glare, eliminating black ice formation during winter (a nearly invisible thin layer of ice formed by frost and fog, extremely dangerous), enhancing the comfort and safety of vehicle and pedestrian traffic.

(6) Large voids can absorb urban pollutant dust, reducing dust pollution.

(7) Can be adjusted according to the environment and function Can require design patterns, colors, fully integrated with the surrounding environment.

Permeable concrete paving is a type developed and used by countries like Europe, the US, Japan, and others to address the deficiencies in the surfaces of original urban roads. It allows rainwater to infiltrate the ground, effectively replenishing groundwater and alleviating urban environmental issues such as the rapid decline in groundwater levels.

Effectively eliminates the environmental hazards caused by oil compounds and other pollutants on the ground; simultaneously, it is an excellent paving material for protecting groundwater, maintaining ecological balance, and alleviating the urban heat island effect; it holds special significance for the benign development of the human living environment and in urban rainwater management and water pollution control.
