Porous concrete, developed and utilized by countries such as Europe, the United States, Japan, and others to address the deficiencies of original urban road surfaces, allows rainwater to infiltrate the ground, effectively replenishing groundwater and alleviating rapid groundwater level decline in cities. It also effectively eliminates the environmental hazards posed by oil compounds and other pollutants on the surface. Additionally, it serves as an excellent paving material for protecting groundwater, maintaining ecological balance, and mitigating the urban heat island effect. It holds particular significance in the benign development of the human living environment, as well as in urban rainwater management and water pollution prevention efforts.
1. Increase the permeable and breathable areas in cities, enhance the heat and moisture exchange between the ground surface and air, regulate the urban climate, reduce surface temperatures, and benefit in alleviating the urban "heat island" phenomenon.
2. Maximize the use of rain and snowmelt, increase the surface relative humidity, 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. Helps alleviate the burden on road drainage systems during the rainy season, significantly reducing pollution of urban water bodies during heavy rainfall.
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; enhances the comfort and safety of both vehicle and pedestrian traffic.
5. Prevents surface water accumulation and nighttime road reflections, 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), enhancing the comfort and safety for both vehicles and pedestrians.
6. Large voids can absorb urban pollutants and dust, reducing dust pollution.
