Abstract
Description
Technical Field
[0001] This utility model relates to the field of road structure technology, specifically to a recycled aggregate pavement structure. Background Technology
[0002] With the rapid pace of urbanization and industrialization in my country, urban construction is shifting from extensive development and large-scale urban renewal to large-scale residential development and road expansion and reconstruction, necessitating large-scale road construction and building demolition. However, road construction requires a large amount of crushed stone for the road base, primarily sourced from mountain gravel. As mining continues, these resources become increasingly scarce, damaging the geological and ecological environment. Furthermore, the waste generated during building demolition, including spills, dust, and ash, easily causes environmental pollution during transport and storage. Utility Model Content
[0003] The purpose of this invention is to design a recycled aggregate pavement structure that can solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A recycled aggregate pavement structure includes a recycled aggregate layer from construction waste, a filter layer on top of the recycled aggregate layer, a permeable layer on top of the filter layer, a crack-resistant layer on top of the permeable layer, a noise-reducing layer on top of the crack-resistant layer, and an asphalt mixture layer on top of the noise-reducing layer.
[0006] Furthermore, a ceramic particle layer is laid on top of the asphalt mixture layer.
[0007] Furthermore, the filter layer is a coarse sand layer.
[0008] Furthermore, the permeable layer is a permeable concrete layer.
[0009] Furthermore, the crack-resistant layer is a basalt fiber concrete layer.
[0010] Furthermore, the noise reduction layer is a gravel layer.
[0011] Furthermore, the asphalt mixture layer is a rubber asphalt concrete layer.
[0012] The beneficial effects of this utility model are as follows:
[0013] By using recycled aggregate from construction waste as the base layer for road construction, construction waste is utilized rationally and resourcefully, reducing environmental pollution and the consumption of crushed stone materials for roads, and minimizing damage to the geological and ecological environment. The noise reduction layer reduces road noise and significantly improves driving comfort. The crack-resistant layer enhances the road's resistance to fatigue cracking and extends its service life. The permeable layer strengthens the road's permeability, replenishes groundwater resources, and alleviates urban flooding. The filtration layer filters out impurities in the water, preventing pollution of groundwater resources. Attached Figure Description

[0017] 1. Recycled aggregate layer from construction waste; 2. Filter layer; 3. Permeable layer; 4. Crack-resistant layer; 5. Noise-reducing layer; 6. Asphalt mixture layer; 7. Ceramic particle layer. Detailed Implementation
[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0019] like Figure 1 As shown, a recycled aggregate pavement structure includes a recycled aggregate layer 1 made from construction waste. The recycled aggregate layer 1 is used as the base layer for road construction, which makes reasonable use of construction waste resources, reduces environmental pollution and the consumption of crushed stone materials for roads, reduces damage to the geological and ecological environment, and the internal pore structure of the recycled aggregate enables it to have rapid drainage capacity, reducing the risk of water accumulation and flooding.
[0020] A filter layer 2 is laid on top of the recycled aggregate layer 1. The filter layer 2 is a coarse sand layer. Because the gaps between the coarse sand are small, when water flows through the filter layer 2 composed of coarse sand, the filter layer 2 will filter the impurities in the water, thereby preventing water from polluting groundwater resources as much as possible.
[0021] The top of the filter layer 2 is covered with a permeable layer 3, which is a permeable concrete layer. Through its internal pores, rainwater can quickly infiltrate, enhancing the permeability of the road, replenishing groundwater resources, and alleviating waterlogging problems. At the same time, its porous structure can also intercept pollutants in the water and purify rainwater that enters the ground.
[0022] The top of the permeable layer 3 is covered with a crack-resistant layer 4, which is a basalt fiber concrete layer. The basalt fiber concrete effectively inhibits crack propagation through the three-dimensional network distribution of fibers, thereby improving the road's fatigue crack resistance and service life. In addition, the basalt fiber concrete layer has high permeability.
[0023] The top of the crack-resistant layer 4 is covered with a noise reduction layer 5, which is a crushed stone layer. The crushed stone can effectively absorb the vibration and noise between the wheels and the road surface, reduce road noise, and the crushed stone layer has high water permeability.
[0024] The top of the noise reduction layer 5 is covered with an asphalt mixture layer 6, which is a rubber asphalt concrete layer. Rubber asphalt concrete can improve the service life of the road surface, reduce noise, reduce vibration, improve thermal stability and thermal cracking resistance, and improve icing resistance. It can reuse waste rubber tires, which not only reduces the accumulation and disposal costs of waste, but also reduces the overall cost of road construction and reduces the pollution of waste tires to the environment. By "turning waste into treasure", it promotes the recycling of resources. In addition, rubber asphalt concrete also has high permeability.
[0025] A ceramic particle layer 7 is laid on top of the asphalt mixture layer 6. The ceramic particle pavement significantly improves the anti-skid performance in rainy weather, greatly shortens the braking distance, reduces road slippage, and lowers the risk of traffic accidents.
[0026] Working principle:
[0027] like Figure 1As shown, the construction of the recycled aggregate pavement structure uses the recycled aggregate layer 1 from construction waste as the base layer of the road construction, making rational use of construction waste resources, reducing environmental pollution and the consumption of crushed stone materials for roads, and reducing damage to the geological and ecological environment. The crack-resistant layer 4, composed of basalt fiber concrete, effectively inhibits crack propagation through the three-dimensional network distribution of fibers, thereby improving the road's fatigue crack resistance and service life. The noise reduction layer 5, composed of crushed stone, can effectively absorb vibration and noise between wheels and the road surface, reducing road noise. The asphalt mixture layer 6, composed of rubber asphalt concrete, can improve the service life of the road surface, reduce noise, reduce vibration, improve thermal stability and thermal cracking resistance, and improve icing resistance. It can reuse waste rubber tires, which not only reduces the accumulation and treatment costs of waste, but also reduces the overall cost of road construction and reduces the pollution of waste tires to the environment. Through the "turning waste into treasure" approach, it promotes the recycling of resources. The ceramic particle pavement significantly improves the anti-skid performance in rainy weather, greatly shortens the braking distance, reduces road slippage, and reduces the risk of traffic accidents.
[0028] Furthermore, the road has good permeability, which can quickly drain water from the road surface, prevent vehicles from skidding, replenish groundwater resources, reduce the pressure on the urban drainage system, and alleviate waterlogging problems. The gaps between the coarse sands in the coarse sand layer are small, so when water flows through the filter layer 2 composed of coarse sand, the filter layer 2 will filter out the debris in the waterway, thereby preventing water from polluting groundwater resources as much as possible.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
