Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement, and more specifically, to a fine anti-skid asphalt pavement. Background Art

[0002] In recent years, semi-rigid asphalt concrete roads have become the main structural type of highways in my country. Asphalt pavement has a dominant position due to its smooth surface, comfortable driving, low noise, good vibration damping, and the recyclability of old asphalt mixtures.

[0003] However, the existing asphalt pavement's insufficient anti-skid performance directly affects driving safety, especially at high speeds. In addition, if rainwater on the asphalt pavement is not discharged in time on rainy days, it will cause traffic accidents and affect its use effect.

[0004] After searching, a Chinese patent with authorization announcement number CN206887674U discloses a fine anti-skid asphalt pavement. This structure can effectively improve the anti-skid effect of the pavement by bonding an anti-slip block to the upper part of the gravel layer and the asphalt layer through an adhesive layer, while ensuring the anti-skid and anti-cracking functions of the pavement. By arranging a second drainage hole between the adhesive layer and the anti-slip block, and a first drainage hole between the gravel layer and the asphalt layer, a drainage hole is opened in the upper part of the drainage pipe near the concrete layer, and the drainage hole, the first drainage hole, and the second drainage hole are connected, the waterproof effect of the pavement can be effectively improved. The utility model has a simple structure and is easy to construct. It can quickly drain the surface water of the pavement, ensure that the anti-slip block will not detach from the pavement, enhance the anti-skid effect of the asphalt pavement, ensure the safety of vehicles, and reduce traffic accidents.

[0005] However, in actual use of this structure, when the vehicle is traveling at high speed and in humid conditions, rainwater flowing in through the second drainage hole must also pass through the first drainage hole and the leak hole before being discharged, resulting in slow drainage speed. If the anti-sliding block is made of small stones, it will be submerged by rainwater, making it difficult to destroy the water film, and thus water skiing is likely to occur. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fine anti-skid asphalt pavement to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A fine anti-skid asphalt pavement comprises a base layer, a foundation stone layer is fixedly laid on the top of the base layer, a waterproof layer is fixedly provided on the top of the foundation stone layer, and a drainage mechanism is fixedly provided on the top of the waterproof layer;

[0009] The drainage mechanism includes a water guide plate fixedly arranged on the top of the waterproof layer, drainage pipes are fixedly arranged on both sides of the water guide plate, drainage ports are opened on both sides of the drainage pipes, a surface layer is fixedly arranged on the top of the drainage pipe, an anti-slip layer is fixedly arranged on the top of the surface layer, drainage holes are opened on the surfaces of the anti-slip layer and the surface layer, a large-particle aggregate layer and a small-particle aggregate layer are fixedly arranged on the surface of the anti-slip layer, and the small-particle aggregate layer is arranged on one side of the large-particle aggregate layer.

[0010] By adopting the above technical solution: in order to quickly drain rainwater from the road surface, hydroplaning on rainy days is effectively prevented, thereby enhancing the anti-skid performance.

[0011] As a further description of the above technical solution: a protective mechanism is provided on the surface of the anti-slip layer, and the protective mechanism includes an anti-slip strip embedded in the anti-slip layer, and both sides of the anti-slip strip are set to an inclined shape. The anti-slip strip is made of rubber material, and a plurality of longitudinal reinforcing steel bars are fixedly provided on the top of the bedstone layer, and both sides of the water guide plate are set to an inclined shape, and stable gravel is fixedly provided between the water guide plate and the surface layer.

[0012] By adopting the above technical solution: in order to increase the contact area and friction with the tire, it also effectively plays a diversion effect, further improving the anti-skid effect.

[0013] As a further description of the above technical solution: one end of multiple longitudinal reinforcing steel bars passes through the waterproof layer and the water guide plate and extends to the outside of the water guide plate, one end of the longitudinal reinforcing steel bars is fixedly connected to the bottom of the surface layer, and transverse reinforcing steel bars are welded on one side of the longitudinal reinforcing steel bars. Both ends of the transverse reinforcing steel bars pass through the drain pipe and extend to the inside of the drain pipe. Limiting blocks are fixedly provided at both ends of the transverse reinforcing steel bars, a first adhesive layer is provided between the anti-slip strip and the anti-slip layer, and a second adhesive layer is provided between the surface layer and the anti-slip layer.

[0014] By adopting the above technical solution: in order to improve the overall stability, the overall use effect is enhanced.

[0015] The technical effects and advantages of this utility model are:

[0016] 1. By providing a drainage mechanism, compared with the existing technology, rainwater falls on the surface of the anti-skid layer, and a portion flows into the interior of the drainage pipe through the drainage holes. Moreover, when rainwater falls on the surface of the anti-skid layer, it can be quickly drained through the large-particle aggregate layer and stable gravel, reducing the impact of rainwater on the road surface and thus improving the anti-skid performance. In addition, both sides of the anti-skid strip are arranged in an inclined shape, which can quickly guide the drainage of accumulated water between the tire and the road surface, reduce the formation of water film, and improve the anti-skid performance. At the same time, rainwater flows into the interior of the drainage pipe through the diversion of the water guide plate, thereby draining water over a large area, preventing water accumulation on the road surface, and further reducing the formation of water film, thereby improving the anti-skid performance of the road surface.

[0017] 2. By setting up a protective mechanism, compared with the existing technology, the density of the road surface is ensured by laying a foundation stone layer on the top of the base layer, and the strength is ensured to meet the requirements through longitudinal and transverse reinforcement steel bars, which can effectively improve the stability of the road surface. The waterproof layer can effectively prevent moisture from penetrating into the base layer and foundation stone layer, avoiding softening and damage of the base layer. The close arrangement of small-particle aggregate layer and large-particle aggregate layer can increase the contact area between the tire and the road surface, increase friction, and enhance the anti-skid effect. When the vehicle tire rolls over the anti-skid strip, the anti-skid strip will be slightly deformed, the contact area with the tire will increase, and the friction will also increase, further improving the anti-skid effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The drainage mechanism includes a water guide plate 4 fixedly arranged on the top of the waterproof layer 3, a drainage pipe 5 is fixedly arranged on both sides of the water guide plate 4, a drainage port is opened on both sides of the drainage pipe 5, a surface layer 7 is fixedly arranged on the top of the drainage pipe 5, an anti-skid layer 8 is fixedly arranged on the top of the surface layer 7, and drainage holes 9 are opened on the surfaces of the anti-skid layer 8 and the surface layer 7, a large-size aggregate layer 10 and a small-size aggregate layer 11 are fixedly arranged on the surface of the anti-skid layer 8, and the small-size aggregate layer 11 is arranged on one side of the large-size aggregate layer 10, rainwater falls on the surface of the anti-skid layer 8, and a part of it flows into the interior of the drainage pipe 5 through the drainage holes 9, and when rainwater falls on the surface of the anti-skid layer 8, due to the large-size aggregate layer 10 The gaps between them also help to drain water, keep the road surface dry, and allow rainwater to flow downward onto the stable gravel 16. The stable gravel 16 has a large porosity and can quickly drain water, reducing the impact of rainwater on the road surface, thereby improving the anti-skid performance. Moreover, both sides of the anti-skid strip 12 are set to an inclined shape, which can quickly guide the accumulated water between the tire and the road surface to drain, reduce the formation of water film, and improve the anti-skid performance. At the same time, rainwater passes through the stable gravel 16 and then falls onto the water guide plate 4, and then falls into the interior of the drain pipe 5 through the inclined sides of the water guide plate 4, so that water can be drained over a large area, preventing water accumulation on the road surface, thereby reducing the formation of water film, thereby improving the anti-skid performance of the road surface.

[0027] Reference Figure 2-3As shown, the surface of the anti-skid layer 8 is provided with a protective mechanism, which includes an anti-skid strip 12 embedded in the anti-skid layer 8. Both sides of the anti-skid strip 12 are set to be inclined. The anti-skid strip 12 is made of rubber material. A plurality of longitudinal reinforcing steel bars 13 are fixed on the top of the base stone layer 2. Both sides of the water guide plate 4 are set to be inclined. Stable gravel 16 is fixed between the water guide plate 4 and the surface layer 7. The small-size aggregate layer 11 and the large-size aggregate layer 10 are closely arranged to increase the contact area between the tire and the road surface. At the same time, the protrusions of the small-particle aggregate layer 11 can better embed into the tire pattern and enhance the anti-skid effect, while the gaps between the large-particle aggregate layer 10 also help to drain water and keep the road surface dry, thereby effectively destroying the water film between the tire and the road surface and preventing hydroplaning. Secondly, since the anti-skid strip 12 is made of rubber material, it itself has a certain elasticity. When the vehicle tire rolls over the anti-skid strip 12, the anti-skid strip 12 will be slightly deformed, the contact area with the tire will increase, and the friction will also increase accordingly.

[0028] Reference Figure 4-5 As shown, one end of multiple longitudinal reinforcing steel bars 13 penetrates the waterproof layer 3 and the water guide plate 4 and extends outside the water guide plate 4, one end of the longitudinal reinforcing steel bar 13 is fixedly connected to the bottom of the surface layer 7, and a transverse reinforcing steel bar 14 is welded on one side of the longitudinal reinforcing steel bar 13. Both ends of the transverse reinforcing steel bar 14 penetrate the drainage pipe 5 and extend inside the drainage pipe 5. Both ends of the transverse reinforcing steel bar 14 are fixedly provided with a limiting block 15. A first adhesive layer 17 is provided between the anti-slip strip 12 and the anti-slip layer 8, and a second adhesive layer 18 is provided between the surface layer 7 and the anti-slip layer 8. By laying the foundation stone layer 2 on the top of the base layer 1, it is ensured that the road The density of the surface is improved, and the longitudinal reinforcement steel bars 13 and the transverse reinforcement steel bars 14 are welded together to ensure that the strength meets the requirements, which can effectively improve the stability of the road surface. The waterproof layer 3 can effectively prevent moisture from penetrating into the base layer 1 and the foundation stone layer 2, avoiding softening and damage to the base layer. The anti-skid strip 12 and the anti-skid layer 8 are firmly bonded together through the first adhesive layer 17 and the second adhesive layer 18, and the surface layer 7 and the anti-skid layer 8 are also firmly bonded together to prevent the road surface from being delaminated under the influence of factors such as vehicle load and temperature changes, thereby reducing the possibility of cracks.

[0029] Working principle of this utility model:

[0030] The utility model is a fine anti-skid asphalt pavement. When the device is in use, the base layer 1 is laid with a foundation stone layer 2 to ensure the density of the pavement. The longitudinal reinforcement steel bars 13 and the transverse reinforcement steel bars 14 are welded together to ensure that the strength meets the requirements, which can effectively improve the stability of the pavement. The waterproof layer 3 can effectively prevent moisture from penetrating into the base layer 1 and the foundation stone layer 2, thereby avoiding softening and damage to the base layer.

[0031] On sunny days, the close arrangement of the small-size aggregate layer 11 and the large-size aggregate layer 10 can increase the contact area between the tire and the road surface, thereby improving friction. At the same time, the protrusions of the small-size aggregate layer 11 can better embed into the tire pattern, thereby enhancing the anti-skid effect. The gaps between the large-size aggregate layer 10 also help to drain water, keep the road surface dry, and thus effectively destroy the water film between the tire and the road surface, thereby preventing hydroplaning. Secondly, since the anti-skid strip 12 is made of rubber material, it itself has a certain elasticity. When the vehicle tire rolls over the anti-skid strip 12, the anti-skid strip 12 will deform slightly, the contact area with the tire will increase, and the friction will also increase accordingly. Moreover, the first adhesive layer 17 and the second adhesive layer 18 firmly adhere the anti-skid strip 12 and the anti-skid layer 8 together, and the surface layer 7 and the anti-skid layer 8 are also firmly adhered together, thereby preventing the road surface from stratifying under the influence of factors such as vehicle load and temperature changes, thereby reducing the possibility of cracks.

[0032] When it rains, rainwater falls on the surface of the anti-skid layer 8, and part of it flows into the inside of the drainage pipe 5 through the drainage holes 9. When rainwater falls on the surface of the anti-skid layer 8, the gaps between the large-particle aggregate layers 10 also help to drain water, keeping the road surface dry, and then the rainwater flows downward onto the stable gravel 16. The stable gravel 16 has a large porosity and can quickly drain water, reducing the impact of rainwater on the road surface, thereby improving the anti-skid performance. Moreover, both sides of the anti-skid strip 12 are set to an inclined shape, which can quickly guide the accumulated water between the tire and the road surface to drain, reduce the formation of water film, and improve the anti-skid performance. At the same time, the rainwater passes through the stable gravel 16 and then falls onto the water guide plate 4, and then falls into the inside of the drainage pipe 5 through the water guide plate 4 with both sides set to an inclined shape, so that it can drain water over a large area, prevent water accumulation on the road surface, and then reduce the formation of water film, thereby improving the anti-skid performance of the road surface.

[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
