With the rapid development of society and economy, the area of urbanization has been expanding. Most pavement materials are cement and asphalt. These materials do not have functions. The usage rate of cement and asphalt pavement has reached about 80% in some areas, this will lead to a high rate of urban road surface hardening, rain and snow weather prone to large areas of water, water level caused by a sharp decline in the ground subsidence and "urban desertification" and other issues. For these reasons, the idea of permeable bricks is exploited. Permeable brick is a kind of brick body which connects the ground water and the city road through its physical properties. This material can penetrate into the surface water, keep the soil moist, solve the problem such as the surface water temperature is too high.
