Huaihua City colored pervious concrete paver materials for non-sticky and high-permeability road construction technology

Porous concrete paving, as a new type 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.

(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, lower the ground temperature, and benefit in alleviating the "urban heat island" phenomenon.

(2) Make full 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 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 reflects less at night.

(5) Prevents surface water accumulation and road reflection at night, eliminating black ice formation 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 vehicle and pedestrian traffic.

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

(7) Patterns and colors can be designed according to environmental and functional requirements, ensuring a perfect blend with the surrounding environment.

The Color-Permeable Concrete Paving System is primarily used for pedestrian walkways, bike paths, public squares, outdoor parking lots, light traffic lanes, park roads, and roadside and median strips.

Porous concrete flooring is a lightweight concrete made from aggregates, cement, and water. It contains no fine aggregates and forms a honeycomb-like structure with uniformly distributed holes, bonded together by a thin layer of cement paste on the surface of the coarse aggregates. Thus, it boasts features such as breathability, water permeability, and light weight.
