Porous concrete paving, as a new type of urban paving, allows rainwater to infiltrate underground through the paving structure by utilizing large pore structural layers or drainage permeation facilities, thereby controlling surface runoff and promoting rainwater utilization.

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

(2) Maximize the use of rainfall and snowmelt to increase the relative humidity of the surface, replenish the increasingly depleted groundwater resources in urban areas, and utilize permeable roadbeds as "water storage basins"; 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 caused by heavy rain.

(4) Absorbs noise generated by vehicle movement, creating a quiet and comfortable living and traffic environment, preventing road surface water accumulation during rain and reflecting light at night.

(5) Prevents surface water accumulation and reflective glare at night, thus avoiding the formation of black ice on roads during winter (a nearly invisible thin layer of ice formed by frost and fog, extremely dangerous). This improves the comfort and safety of vehicles and pedestrians.

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

(7) Patterns and colors can be designed to match the environment and functional requirements, ensuring a seamless integration with the surrounding area.

Porous concrete, as an environmentally friendly load-reducing concrete, not only offers excellent permeability and sufficient rainwater collection, but also provides functions such as noise absorption and reduction, flood resistance, and alleviation of urban "heat island effect."
