Description

Technical Field

[0001] The utility model relates to the technical field of road surfaces, in particular to an energy-saving and environment-friendly road surface. Background Art

[0002] With the continuous growth of my country's economy and the acceleration of urbanization, road construction has achieved remarkable achievements. A high-quality road needs to meet many requirements such as driving safety, comfort, economy and environmental protection, and these requirements depend to a large extent on the road surface material. The road surface refers to one or more road structure layers laid on the top of the roadbed with road building materials for vehicles to drive directly on its surface. The layered structure laid on the roadbed with road building materials for vehicles to drive has the functions of bearing the weight of vehicles, resisting wheel wear and keeping the road surface flat. For this reason, the road surface is required to have sufficient strength, high stability, a certain degree of flatness, appropriate anti-skid ability, and no excessive dust when driving, so as to reduce damage to the road surface and vehicle parts, maintain a good sight distance, and reduce environmental pollution;

[0003] Chinese patent authorization announcement number CN212771826U discloses an energy-saving and environmentally friendly road pavement, including a roadbed, a wood fiber base plate installed on the top of the roadbed, a buffer layer connected to the top of the wood fiber base plate, water-permeable pipes installed on both sides of the interior of the buffer layer, and a permeable asphalt bottom layer is laid on the top of the buffer layer, and a permeable asphalt surface layer is installed on the top of the permeable asphalt bottom layer. The utility model uses the cooperation of the limit block and the limit groove to tightly combine the wood fiber base plate and the roadbed together, preventing the wood fiber base plate from shifting on the roadbed, thereby fixing the wood fiber base plate, and by cooperating the first reinforcing rib and the second reinforcing rib, the compressive performance of the wood fiber base plate can be enhanced, thereby protecting the wood fiber base plate and preventing it from breaking, and at the same time, the wood fiber base plate can be further stabilized on the roadbed, thereby increasing the service life of the road surface.

[0004] The above-mentioned existing technical solutions have the following shortcomings: when the technical solution is in use, a certain degree of pressure resistance is provided by the rubber seat and the buffer spring. This structure can only reduce the impact on the road surface to a certain extent, and the strength of the road surface itself lacks a corresponding enhanced design, which leads to poor load-bearing effect. When the gravity borne by the road surface is too large, it will cause damage to the road surface, and then affect the normal operation of the road. Therefore, corresponding improvements are needed.
