Concept and Definition

Permeable pavement is a type of porous, lightweight, high-strength concrete ground material. Primarily composed of coarse and fine aggregates, it is formed through methods like continuous compaction pouring or vibratory compaction. Its defining feature is the ability to allow water to infiltrate the ground, thereby replenishing water resources and improving urban ecosystems.

Importance

The significance of permeable pavement is reflected in the following aspects:

Improving Urban Water Resources: With deepening urbanization, water scarcity intensifies. Permeable pavement enables rainwater infiltration into the ground, replenishing water resources and enhancing urban water conditions.

Reducing Burden on Urban Drainage Systems: Traditional impervious asphalt pavements hinder water penetration, increasing pressure on urban drainage systems. Permeable pavement effectively alleviates this pressure and reduces the load on drainage infrastructure.

Enhancing Residents' Quality of Life: Permeable pavement helps lower surface temperatures, mitigates the urban heat island effect, and improves residents' living standards.

Promoting Urban Sustainable Development: With features like environmental friendliness and low energy consumption, permeable pavement aligns with sustainable development requirements. Its widespread application fosters sustainable urban growth and enhances a city’s attractiveness.

In summary, permeable pavement is a novel concrete pavement material with unique advantages, now widely adopted in modern urban construction. Its extensive use improves...
