The concept definition and significance of permeable pavement: Permeable pavement is a type of porous, lightweight, and high-strength concrete ground material. It is mainly composed of coarse aggregates and fine aggregates, and is made by continuous density pouring or vibration compaction. The main feature of this type of floor material is that it allows water to seep into the ground, thereby further replenishing water sources and improving the urban ecosystem.

The necessity of permeable pavement is mainly reflected in the following aspects:

Improving urban water resources: With the continuous deepening of urbanization, water sources are becoming increasingly scarce. Permeable pavement allows rainwater and other moisture to seep into the ground, replenishing water sources and thus changing the water resource situation in cities.

Reducing the burden on urban drainage systems: Traditional hard asphalt pavements are not prone to seepage and can easily cause pressure on urban drainage pipes. Permeable pavement can effectively relieve the pressure on urban drainage pipes and reduce the burden on urban drainage systems.

Improving the quality of life for residents: Permeable pavement can effectively reduce the ground environmental temperature, alleviate the heat island effect, and enhance the quality of life for residents.

Promoting sustainable urban development: Permeable pavement features environmental friendliness and low energy consumption, which complies with the regulations of sustainable development. Its wide application can promote sustainable urban development and enhance the city's appeal to talents.

In conclusion, permeable pavement is a new type of concrete asphalt pavement with its own unique advantages and has been widely used in contemporary urban construction. Its wide application can improve
