1. When concentrated rainfall occurs, it can alleviate the burden on urban drainage facilities, preventing river flooding and water pollution.

3. Prevents water accumulation on the road surface, does not reflect at night, enhancing road safety and comfort for passage.

5. High porosity can reduce road noise during vehicle travel, creating a comfortable traffic environment.

7. Easy to maintain, gaps won't tear, and not prone to blockage.

Porous pavement roads add color to sponge city construction! The construction technology of permeable concrete is a crucial method to achieve road spongeification, enabling the end-of-pipe collection of rainwater, storing moisture at the surface, nourishing groundwater and surrounding vegetation. Porosity reaches 15-25%, mitigating the urban heat island effect.

Natural Aggregate Permeable Pavement Construction Steps: Mix a measured amount of stone, cement, binder, and water until well blended. Moisten the subgrade with water before laying, compact and level the subbase. Smooth and finish the surface layer with a cement smoothing machine. Cover with agricultural film for two days after construction and then water it for maintenance, which takes about five to seven days. Set up isolation zones to prevent pedestrian traffic during this period. After the surface dries, apply a surface sealant (also known as a surface罩剂).
