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

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

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

（3Eases the burden on road drainage systems during the rainy season, significantly reducing the pollution of urban water bodies caused by heavy rain.

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

（5To prevent road puddles and night-time glare, it ensures no black ice forms on the road during winter (a nearly invisible thin layer of ice formed by frost and fog, extremely dangerous), enhancing the comfort and safety of both vehicle and pedestrian traffic.

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

（7Patterns and colors can be designed to suit environmental and functional needs, blending seamlessly with the surrounding environment..

Aggregate-Exposed Permeable Concrete is a decorative type of permeable concrete, with its color and texture determined by natural colored aggregates. Its construction not only employs the colored and reinforced permeable concrete technique but also involves uniformly spraying a surface etching agent on the wet, newly constructed Aggregate-Exposed Permeable Concrete surface, followed by a pressure washing operation with appropriate water pressure within a suitable timeframe.
