Description

Technical Field

[0001] The present application relates to the technical field of permeable roads, and in particular to a permeable road pavement structure. Background Art

[0002] A permeable road is a road system that allows rainwater to penetrate the pavement structure and directly seep into the ground. It is mainly composed of a permeable pavement layer, a base layer, and a soil base. Permeable roads can effectively reduce surface runoff. During rainfall, rainwater can quickly seep into the ground instead of forming water accumulation on the road surface. At present, some permeable roads are usually paved with permeable bricks to improve the aesthetics. Permeable bricks also have high permeability. However, when laying permeable bricks, in order to ensure the stability of the road surface and prevent the permeable bricks from moving around at will, the permeable bricks are tightly fitted together. Broken permeable bricks are not easy to pull out, making it difficult to replace the permeable bricks and requiring a lot of manpower and material resources for maintenance. Therefore, in order to solve the above problems, the present application provides a permeable road paving structure. Utility Model Content
