Porous concrete road surfaces are a type developed and utilized by countries such as Europe, the United States, Japan, and others to address the deficiencies in existing urban road surfaces. They allow rainwater to infiltrate the ground, effectively replenish groundwater, and alleviate various urban environmental issues, such as the rapid decline in groundwater levels.

Effectively eliminates the environmental hazards caused by oil compounds and other substances on the ground; simultaneously, it is an excellent paving material for protecting groundwater, maintaining ecological balance, and alleviating urban heat island effects. It holds special significance in the benign development of human living environments, as well as in urban rainwater management and water pollution prevention.

The significant advantages of pervious pavement are: rapid water permeability, replenishment of groundwater resources, reduction of the "heat island effect", overall installation with aesthetic appeal and high strength, and suitability for pedestrian and vehicle traffic.

Permeable Concrete Binder——Composed mainly of reinforcing agents, fluidizers, stabilizers, and fibers, this binder, when mixed with aggregates, cement, and pigments, significantly enhances the strength of permeable concrete. It also improves the stability and fluidity of permeable concrete, thereby enhancing its permeability.

(1) Crushed Stone: Crushed stone is one of the main materials for permeable concrete, and its quality must be well-controlled.

(2) Water: Tap water is sufficient. Groundwater that is not filtered or turbid, or water that has been used and is not clean, should not be used.

(3) Cement: 42.5 Portland cement is sufficient.

(4) Pigments: High-quality inorganic pigments
