Pervious concrete is a porous lightweight concrete made by mixing aggregate, cement, and water. As a new environmentally friendly and ecological road material, pervious concrete offers advantages such as breathability, water permeability, and light weight, giving it an irreplaceable role in urban stormwater management and water pollution prevention. Pervious concrete not only utilizes its porosity to achieve free filtration and drainage, but also fully leverages thunderstorm precipitation, exerting the "reservoir function" of the pervious roadbed.
