[0022] Further, the support layer 15 is made of sand, which provides sufficient support for the upper structure and ensures the stability of the road. The drainage layer 16 is made of drainage pipes, which drains excess water and ensures that the road does not accumulate water.

[0023] In more detail, the storage layer 17 is made of sponge-like structure material, which stores rainwater and releases it slowly, preventing the drainage system from being overloaded by too fast water flow. The permeable layer 18 is made of coarse sand particles, which allows water to quickly penetrate to the lower layer without affecting the smoothness of the ground traffic.

[0024] In general, the filter layer 19 is made of non-woven geotextile, which filters out large particles in water and protects the lower drainage system from being blocked.

The pavement layer 112 is made of permeable asphalt, which provides a surface for vehicles to travel on while having some permeability to reduce rainwater accumulation.

[0026] The working mode is as follows: rainwater first enters the buffer layer 110 through the pavement layer 112 and the protective layer 111. The crushed stone material in the buffer layer 110 can slowly release the water flow, reducing the water flow speed and avoiding impact on the lower layer. The water flow continues to pass through the filter layer 19, which filters out impurities and silt in the water to prevent them from blocking the drainage system in the lower layer. The filtered water further penetrates in the permeable layer 18, which is made of coarse sand material, and quickly penetrates into the storage layer 17. The storage layer 17 stores part of the rainwater to relieve the drainage pressure caused by short-term rainfall. The remaining water is guided into the drainage pipes in the drainage layer 16 to ensure that excess water can be quickly drained out of the road system. After the drainage layer 16, the support layer 15 provides structural stability for the road, the isolation layer 14 prevents water from penetrating into the infrastructure, ensuring the long-term stability of the road, and the waterproof layer 13 prevents water from penetrating into the foundation part of the road structure by using high-strength waterproof material.
