Description

Technical Field

[0001] The utility model relates to the technical field of pavement structures, in particular to an anti-cracking asphalt pavement structure. Background Art

[0002] Existing asphalt pavements are prone to melting at high temperatures and cracking at low temperatures in high and low temperature environments due to the lack of necessary anti-cracking structures on the pavement, which affects the flatness and aesthetics of the asphalt pavement. In addition, general asphalt pavements lack shock-absorbing structures inside, so when pressed by vehicles, the pavement is easily subjected to strong pressure and is easily damaged. Summary of the invention

[0003] In order to solve the above problems, the utility model provides the following solutions:

[0004] A crack-resistant asphalt pavement structure comprises an asphalt layer, an anti-cracking layer, a reinforcement layer, a crushed stone layer and a subbase layer; the crushed stone layer is laid on top of the subbase layer, the reinforcement layer is laid on top of the crushed stone layer, the anti-cracking layer is arranged on top of the reinforcement layer, and the asphalt layer is laid on top of the anti-cracking layer; the crack-resistant layer comprises an anti-cracking frame, the anti-cracking frame has embedded plates arranged at intervals, two adjacent embedded plates are connected to a plurality of reinforcement nets, a hard spring is arranged between the two reinforcement nets, and both ends of the hard spring are respectively fixed to the embedded plates; the asphalt layer fills the space between the embedded plates and covers the top of the embedded plates.

[0005] Furthermore, the reinforcement layer is cast by high-strength concrete, and a plurality of reinforcing ribs are arranged at equal intervals in the reinforcement layer.

[0006] Furthermore, a waterproof cloth layer is provided between the reinforcement layer and the gravel layer.

[0007] Furthermore, a shock-absorbing layer is provided between the asphalt layer and the embedded plate.

[0008] Furthermore, the shock-absorbing layer is a non-woven fabric layer wrapped around the embedded plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. The asphalt layer is equipped with an anti-cracking layer to increase the horizontal stress damping. When the road surface undergoes horizontal deformation, the deformation stress is offset by the reinforcement net and hard spring to avoid the problem of road surface cracking due to horizontal stress.

[0011] 2. A non-woven fabric layer is arranged between the asphalt layer and the embedded plate to reduce the impact of the asphalt pavement on the anti-cracking frame and effectively increase the life of the pavement. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] 1. Asphalt layer; 2. Embedded board; 3. Reinforcement mesh; 4. Hard spring; 5. Reinforcement layer; 6. Reinforcement ribs; 7. Gravel layer; 8. Base layer; 9. Non-woven fabric layer; 10. Waterproof fabric layer. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical scheme and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the embodiments. In order to thoroughly understand the present invention, some specific details will be involved in the following description. In the absence of these specific details, the invention of the present invention can still be realized, that is, the description and statement herein can more effectively introduce the nature of their work to other technicians in the field. In addition, it should be noted that it should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the actual protection scope. All raw materials used in the following examples are commercially available products.

[0015] Example 1: Figure 1 As shown, an anti-cracking asphalt pavement structure includes an asphalt layer 1, an anti-cracking layer, a reinforcement layer 5, a crushed stone layer 7 and a base layer 8; the crushed stone layer 7 is laid on the base layer 8, the reinforcement layer 5 is laid on the crushed stone layer 7, the anti-cracking layer is arranged on the reinforcement layer 5, and the asphalt layer 1 is laid on the anti-cracking layer; the anti-cracking layer includes an anti-cracking frame, the anti-cracking frame is provided with embedded plates 2 arranged at intervals, two adjacent embedded plates 2 are connected with a plurality of reinforcement nets 3, a hard spring 4 is arranged between the two reinforcement nets 3, and the two ends of the hard spring 4 are respectively fixed to the embedded plates 2; the asphalt layer 1 fills the space between the embedded plates 2 and covers the top of the embedded plates 2.

[0016] The reinforcement layer 5 is cast from high-strength concrete, and multiple reinforcing ribs 6 are arranged equidistantly in the reinforcement layer 5. A waterproof cloth layer 10 is also arranged between the reinforcement layer 5 and the gravel layer 7. A shock-absorbing layer is arranged between the asphalt layer 1 and the embedded plate 2. The shock-absorbing layer is a non-woven fabric layer 9 wrapped around the embedded plate 2.

[0017] The asphalt layer of the utility model increases the horizontal stress damping by the anti-cracking layer. When the road surface is deformed horizontally, the deformation stress is offset by the reinforcement net 3 and the hard spring 4, thereby avoiding the problem of cracking of the road surface due to horizontal stress. A non-woven fabric layer 9 is arranged between the asphalt layer 1 and the embedded plate 2 to reduce the impact of the asphalt road surface extrusion on the anti-cracking frame, effectively increasing the life of the road surface.

[0018] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
