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

（1Increasing the permeable and breathable area in cities, enhancing the heat and moisture exchange between the surface and air, regulating urban climate, reducing surface temperatures, and benefiting the alleviation of the urban "heat island" phenomenon.

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

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

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

（5Prevents road puddling and night-time reflection, preventing the formation of black ice (a nearly invisible thin layer of ice formed by frost and fog, extremely dangerous) on the road in winter, enhancing the comfort and safety for vehicles and pedestrians.

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

（7Patterns and colors can be designed according to environmental and functional needs, ensuring a full integration with the surrounding environment..

Extruded aggregate pervious concrete is a decorative type of pervious concrete, with its color and texture determined by natural colored aggregates. The construction process not only employs the colored rigid pervious concrete technique but also involves uniformly spraying a surface etching agent on the wet, exposed aggregate pervious concrete surface immediately after construction. Subsequently, water washing operations are conducted with appropriate water pressure within a suitable timeframe.
