Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to an anti-slip asphalt pavement. Background Art

[0002] Road construction refers to the reconstruction, maintenance and new construction of existing roads to improve the road's carrying capacity and service level and ensure traffic safety and smoothness. Asphalt pavement is one of the many projects in road construction. Asphalt pavement is a type of road surface paved with road asphalt materials mixed into mineral materials. This type of pavement is characterized by being flat and dust-free, waterproof, durable, and having a high ability to resist damage to the road surface caused by driving and natural factors. The main raw material for the construction of asphalt pavement is asphalt concrete, which is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate amount of asphalt materials with a certain graded mineral aggregate. Asphalt concrete, as an asphalt pavement material, must withstand the repeated effects of moving vehicle loads and the long-term effects of environmental factors during use. Therefore, it must have good durability, including stability in high temperature environments, crack resistance in low temperature conditions, good water stability, long-lasting anti-aging and anti-skid properties that are beneficial to safety.

[0003] After searching, a utility model patent (or invention patent) with the announcement number CN219260617U specifically discloses an asphalt pavement, including a road body, wherein the road body includes an asphalt layer, a first crushed stone layer, a concrete layer, a second crushed stone layer, and a base layer. After rainwater falls on the road body, it will penetrate into each layer in turn, and at the same time it will also seep out from the left and right sides, and flow into the sewer from the water inlet, greatly reducing the water content in the road body, so that the water in the road body will be quickly lost, thereby reducing the time that the road body is soaked by rainwater, and improving the life of the road body. Large and small debris are filtered out respectively by the cover plate and the filter plate to avoid clogging by debris, and by removing the cover plate and then removing the filter plate from the sewer, the smaller impurities on the filter plate can be cleaned up, and garbage cleaning is more convenient. There is no need for sanitation workers to clean garbage from the drainage pipe, which can reduce the labor intensity of sanitation workers.

[0004] During the use of existing asphalt pavements, road slip is a structural damage phenomenon caused by local hugging bulges due to the instability of the asphalt pavement. If the paved asphalt pavement lacks an anti-slip structure, as the road surface and vehicles become increasingly worn, not only will the road safety be greatly reduced, but the worn asphalt pavement will also require frequent maintenance. In the above-mentioned comparative cases, the asphalt pavement only has connectivity between the materials of the base surface layers themselves, and does not have good anti-slip ability. This reduces the scope of use of the asphalt pavement over a long period of time and increases the workload of road maintenance personnel.

[0005] Therefore, it is necessary to invent a kind of anti-skid asphalt pavement to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an anti-skid asphalt pavement, which forms an anti-skid structure between the entire surface layer and the base layer through a water-cushioned gravel base layer, a cement-stabilized base layer, a steel formwork body, an anti-skid steel frame, an anti-skid asphalt pile body and a lower asphalt surface layer, thereby increasing the stability of the entire asphalt pavement, reducing the hazards of asphalt pavement sliding, improving the overall environmental quality, and at the same time protecting the ground material from damage caused by sliding, thereby extending the service life of the asphalt pavement. In this way, the connectivity of the material of the asphalt pavement base layer itself is enhanced when used in combination, and it has good anti-skid ability, thereby expanding the scope of use of the asphalt pavement and reducing the risk of road erosion. The effect on the work intensity of road maintenance and repair personnel is to solve the structural damage phenomenon of local hugging bulge caused by road slip during the use of asphalt pavement in the prior art. If the paved asphalt pavement lacks an anti-slip structure, as the road surface and vehicles are increasingly worn, not only will the road safety be greatly reduced, but the worn asphalt pavement also requires frequent maintenance. In the above-mentioned comparative case, the asphalt pavement only has the connectivity between the materials of the base surface layer itself, and does not have good anti-slip ability. This reduces the scope of use of the asphalt pavement under long-term use and increases the work intensity of road maintenance and repair personnel.

[0007] In order to achieve the above-mentioned object, the utility model provides the following technical solutions: an anti-slip asphalt pavement, comprising an outer layer of pavement soil, which is used to compact the ground and lay the asphalt pavement;

[0008] The rammed earth subbase is arranged inside the outer road surface soil and is used to bear the load of the asphalt road surface. A water cushion gravel base is attached to the top of the rammed earth subbase, a cement stabilized base is attached to the top of the water cushion gravel base, a steel formwork is attached to the top of the cement stabilized base, and a positioning slot is opened on the surface of the steel formwork;

[0009] An anti-slip steel frame runs through the positioning slot and is used to provide anti-slip capability for the asphalt pavement. A longitudinal partition steel plate is fixedly installed on one side of the anti-slip steel frame, and a transverse enclosure steel plate is fixedly installed on the other side of the longitudinal partition steel plate. An anti-slip asphalt pile body is arranged inside the transverse enclosure steel plate, and a lower asphalt surface layer is adhered to the top of the anti-slip asphalt pile body, and a corrosion-resistant protective layer is adhered to the surface of the lower asphalt surface layer.

[0010] Preferably, the cement stabilized base layer is fixedly connected to the steel formwork body, and the positioning slots are distributed at equal intervals on the steel formwork body.

[0011] Preferably, the transverse enclosure steel plate is welded to the longitudinal partition steel plate, and the anti-slip asphalt piles are distributed at equal intervals on the steel formwork body.

[0012] Preferably, the corrosion-resistant protective layer is tightly fitted to the lower asphalt surface layer, and the material of the corrosion-resistant protective layer is polyurethane.

[0013] Preferably, an upper asphalt surface layer is arranged above the lower asphalt surface layer, an anti-skid protective layer is pasted above the upper asphalt surface layer, and road spacing markings are arranged on the surface of the upper asphalt surface layer.

[0014] Preferably, the upper asphalt surface layer is tightly fitted with the anti-skid protective layer, and the material of the anti-skid protective layer is: epoxy colored sand.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model is provided with a water cushion gravel base, a cement stabilized base, a steel formwork body, an anti-slip steel frame, an anti-slip asphalt pile body and a lower asphalt surface layer. When the asphalt pavement is used, the water cushion gravel base and the cement stabilized base are below the surface layer, which enhance the bearing capacity of the asphalt pavement, fill the unevenness of the base surface, and play a role in dispersing the load, thus ensuring the flatness of the bottom of the base layer. In combination with the anti-slip steel frame penetrating the cement stabilized base layer and the anti-slip asphalt pile body inside the anti-slip steel frame, an anti-slip structure is formed between the entire surface layer and the base layer, thereby increasing the stability of the entire asphalt pavement, reducing the hazards of asphalt pavement slippage, improving the overall environmental quality, and at the same time protecting the ground material from damage to the ground material caused by slippage, thereby extending the service life of the asphalt pavement. In this way, the coordinated use also enhances the connectivity of the material of the asphalt pavement base layer itself, and has good anti-slip ability, thereby expanding the scope of use of the asphalt pavement and reducing the work intensity of road maintenance personnel.

[0017] 2. The utility model is provided with a lower asphalt surface layer, a corrosion-resistant protective layer, an upper asphalt surface layer, an anti-skid protective layer and road interval markings. When the asphalt pavement is used, the corrosion-resistant protective layer and the anti-skid protective layer are arranged on the lower asphalt surface layer and the upper asphalt surface layer, so that the asphalt pavement has higher wear resistance, corrosion resistance and anti-skid ability in daily use, so that when vehicles travel on the asphalt pavement, road driving safety is also increased, and the asphalt pavement has higher resistance to wind and rain, which extends the service life of the asphalt pavement. Moreover, the road interval markings in the middle of the asphalt pavement make it more convenient for vehicles to travel in the specified lanes. BRIEF DESCRIPTION OF THE DRAWINGS
