Problems solved by technology

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environment-friendly building materials. As one of the new functional road paving materials, it can ensure that the water on the road surface penetrates into the ground, has good wear resistance and compression resistance, and is gradually widely used in urban road construction. With the progress of society , energy-saving materials are bound to develop in the direction of multi-functionality. Gum-like macromolecule sticky substances are often pasted on the permeable pavement bricks. With time and the rolling and solidification of people and vehicles, these substances will adhere to the pavement with high strength. On the surface of the brick, on the one hand, it affects the city appearance and increases the cost of road cleaning; on the other hand, it hinders and limits its permeable function, which affects the drainage and flood discharge work
