Permeable concrete is a new type of pavement material, featuring air permeability, water permeability and light weight. It is made by mixing aggregates, cement and water in a certain proportion. It does not contain fine aggregates. The surface of coarse aggregates is coated with a thin layer of cement slurry and bonded together to form a honeycomb structure. Compared with ordinary concrete, permeable concrete has greater strength and can withstand higher vehicle pressure and wear.

Permeable concrete has a wide range of applications and can be used in urban sidewalks, bicycle lanes, square and park roads and other slow lanes, as well as in parking lots, garden landscape roads and other places. It can drain water, resist slipping, absorb sound, reduce noise, and seep water, improve the surface ecological cycle, facilitate driving safety, protect the living environment, and address the negative impacts brought about by large-scale modern urban construction.

In construction applications, the laying of the surface layer of permeable concrete, the spraying of the colored surface layer, the management of the curing period, and the protection of the finished product all need to be strictly controlled. At the same time, it is necessary to pay attention to preventing damage from being crushed by vehicles when they pass. To protect the service life and performance of permeable concrete, appropriate maintenance and care are necessary.

In conclusion, permeable concrete is a new type of pavement material with multiple advantages. It can protect nature and maintain ecological balance, and is suitable for various road construction and renovation projects. In the future, with the continuous advancement of technology and the increasing awareness of environmental protection, the demand for permeable concrete will continue to rise, and its application scenarios will also become increasingly extensive.
