Porous concrete pavement is a lightweight, fine aggregate-free concrete composed of cement, special additives, aggregates, and water mixed in a specific ratio. It is superior, ecological, and environmentally friendly compared to other paving materials, and falls under the fully permeable category. Its features include: water permeability, water retention, and air permeability.

Porous concrete, as an environmentally friendly concrete with reduced load, not only excels in its permeability and adequate rainwater collection, but also offers functions such as noise absorption and reduction, flood resistance, and mitigation of the urban "heat island" effect.

The permeable pavement structure, from top to bottom, is as follows: compacted natural soil, graded crushed stone, and 60~120mm permeable concrete.Pervious concrete construction primarily includes: spreading, shaping, surface treatment, and joint treatment.1) Laying: Can be done by machinery or manually;2) Molding: Construction can be carried out using flat vibrators, vibration leveling rollers, manual push-pull rollers, and vibration leveling beams.3) Surface Treatment: Mainly to enhance the surface appearance, involves trimming or cleaning the formed pervious concrete surface.4) The setting of transverse joints in pervious concrete pavements is similar to that of ordinary concrete, with joints evenly spaced, not exceeding 6 meters apart.

         

Porous pavement, as a new environmentally friendly and ecological road material, is highly suitable for use in urban garden roads and offers excellent overall benefits. It is evident that permeable concrete surfaces contribute positively to the ecological environment of urban garden areas, serving as a crucial foundation for maintaining a healthy ecological cycle. The application of permeable concrete should be vigorously promoted in urban gardens. The comprehensive benefits it yields can be considered as one of the control indicators for urban construction, particularly significant for the maintenance of urban garden construction.

Porous pavement materials are eco-friendly, high-permeability materials used in sponge city construction. They serve as a novel paving method that can partially replace urban paved surfaces, effectively improving the urban ecosystem. These materials breathe life back into the city's surface, allow rainwater to seep into the ground, and effectively eliminate surface water accumulation. They are green, environmentally friendly ground materials that "breathe."
