Description

Technical Field

[0001] The utility model relates to the technical field of pavement structures, in particular to a high-strength crack-resistant pavement structure. Background Art

[0002] With the rapid development of modern social economy, the volume of transportation is increasing. Whether it is the increase in the number of heavy trucks in road transportation or the frequent travel of vehicles on urban roads, higher bearing requirements are put forward for the pavement structure.

[0003] When heavy vehicles pass through frequently, the road surface will be subjected to huge vertical pressure. Due to the limited bearing capacity of traditional pavement structures, the pavement materials will gradually be compressed under this pressure. For example, the asphalt binder in the asphalt pavement may be squeezed out, and the interlocking structure between the aggregates will be destroyed, causing depressions in the road surface. This vertical deformation is particularly obvious in the wheel track of the road. Over time, the depression will become deeper and deeper, seriously affecting the flatness of the road. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-strength crack-resistant pavement structure.

[0005] The utility model adopts the following technical solution: a high-strength crack-resistant pavement structure, including a first roadbed bone plate, the four corners of the upper surface of the first roadbed bone plate are fixedly connected to support steel bars, the upper surface of the first roadbed bone plate is fixedly connected to a plurality of longitudinal reinforcement blocks, the interior of the longitudinal reinforcement blocks is fixedly connected to a plurality of transverse reinforcement ribs, and the upper surface of the support steel bars is fixedly connected to a second roadbed bone plate.

[0006] Through this technical solution, the longitudinal reinforcement blocks on the first roadbed slab and the transverse reinforcement ribs within them work synergistically to enhance the slab's longitudinal and transverse strength. The longitudinal reinforcement blocks strengthen its longitudinal integrity, while the transverse reinforcement ribs prevent the blocks from breaking laterally, thereby improving the durability and load-bearing capacity of the first roadbed slab. The second roadbed slab is connected to the supporting steel columns, further creating a stable double-layer roadbed structure. This provides more uniform support for subsequent pavement layers and reduces the possibility of road surface damage caused by uneven foundation settlement.

[0007] As a further improvement of the above solution, a high modulus asphalt concrete layer is provided on the upper surface of the second roadbed bone plate.

[0008] Through the above technical solution, the high strength of the high modulus asphalt concrete layer helps to disperse the stress generated by vehicle loads and reduce the risk of excessive local stress on the road surface, thereby extending the service life of the road surface and reducing maintenance costs.

[0009] As a further improvement of the above solution, a reinforcement layer is provided on the upper surface of the high modulus asphalt concrete layer, and the material of the reinforcement layer is glass fiber cloth and polyester glass fiber cloth.

[0010] Through the above technical solution, when the road surface is subjected to tensile stress, such as stress caused by temperature changes or vehicle braking and acceleration, the reinforced layer can effectively resist the tensile force, prevent the generation and expansion of road cracks, and improve the overall crack resistance of the road surface.

[0011] As a further improvement of the above solution, an anti-cracking mortar layer is fixedly connected to the upper surface of the reinforcement layer.

[0012] Through the above technical solution, the anti-cracking properties of the anti-cracking mortar layer itself can prevent the further development of tiny cracks that may appear in the road surface during use, play a role in protecting and reinforcing the road surface, and improve the overall quality and service life of the road surface.

[0013] As a further improvement of the above solution, a wear layer is fixedly connected to the upper surface of the anti-cracking mortar layer.

[0014] As a further improvement of the above solution, the material of the wearing layer is modified asphalt.

[0015] Through the above technical solution, the wearing layer is made of modified asphalt with excellent wear resistance. It directly bears the wear of vehicle tires, effectively reducing the wear rate of the road surface, maintaining the smoothness and roughness of the road surface, and improving driving safety.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model enhances the longitudinal and transverse strength of the roadbed bone plate by arranging longitudinal reinforcement blocks on the first roadbed bone plate and transverse reinforcement ribs inside the first roadbed bone plate to prevent deformation and fracture. This design improves the overall bearing capacity of the pavement from the basic structure. The first roadbed bone plate and the second roadbed bone plate connected by the supporting steel column jointly construct a stable double-layer roadbed structure, which can better bear the weight and stress of subsequent road surface layers and ensure the stability of the road surface structure during long-term use. At the same time, the high strength of high modulus asphalt concrete also helps to disperse stress and prevent excessive stress concentration in local areas of the road surface from causing cracks.

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 The high-strength and crack-resistant pavement structure of this embodiment includes a first roadbed bone plate 1, and the four corners of the upper surface of the first roadbed bone plate 1 are fixedly connected to support steel bars 2. The upper surface of the first roadbed bone plate 1 is fixedly connected to several longitudinal reinforcement blocks 3, and the interior of the longitudinal reinforcement blocks 3 is fixedly connected to several transverse reinforcement ribs 4. The upper surface of the support steel bar column 2 is fixedly connected to a second roadbed bone plate 5. The longitudinal reinforcement blocks 3 on the upper surface of the first roadbed bone plate 1 increase the strength of the roadbed bone plate in the longitudinal direction, and the transverse reinforcement ribs 4 inside the longitudinal reinforcement blocks 3 further enhance the overall strength of the longitudinal reinforcement blocks 3 to prevent them from deformation or fracture in the transverse direction. The second roadbed bone plate 5 fixedly connected to the upper surface of the support steel bar column 2 constructs the second layer foundation of the pavement structure, and together with the first roadbed bone plate 1, bears the weight and stress of the subsequent pavement layer.

[0027] A high modulus asphalt concrete layer 6 is provided on the upper surface of the second roadbed bone plate 5. The high modulus asphalt concrete layer 6 located on the upper surface of the second roadbed bone plate 5 has a high modulus, which means that it has a high deformation resistance. At the same time, the high strength of the high modulus asphalt concrete also helps to disperse stress and prevent excessive stress concentration in local areas of the road surface, which may lead to cracks.

[0028] A reinforcement layer 7 is provided on the upper surface of the high modulus asphalt concrete layer 6. The reinforcement layer 7 is made of glass fiber cloth and polyester glass fiber cloth. The reinforcement layer 7 is located on the upper surface of the high modulus asphalt concrete layer 6. Its material is glass fiber cloth and polyester glass fiber cloth. These materials have high tensile strength. When the road surface is subjected to tensile stress, the reinforcement layer 7 can withstand part of the tensile force and prevent the expansion of road cracks. For example, when the road surface generates tensile force due to temperature changes or vehicle loads, the glass fiber cloth and polyester glass fiber cloth can disperse the tensile force to the entire reinforcement layer 7 like a mesh structure, thereby reducing the generation and expansion of road cracks.

[0029] The upper surface of the reinforcement layer 7 is fixedly connected with an anti-cracking mortar layer 8. The anti-cracking mortar has good adhesion and flexibility, can fill the tiny gaps that may appear on the road surface, and when the road surface is subjected to external force, it absorbs part of the energy through its own deformation ability to prevent further development of cracks.

[0030] A wear layer 9 is fixedly connected to the upper surface of the anti-cracking mortar layer 8 .

[0031] The material of the wear layer 9 is modified asphalt. The wear layer 9 mainly bears the direct wear and friction of the vehicle tires. The characteristics of the modified asphalt make it have good wear resistance. At the same time, the wear layer 9 can also resist the erosion of natural factors such as rain and sunlight, protect the underlying pavement structure, and extend the service life of the entire pavement structure.

[0032] The implementation principle of a high-strength, crack-resistant pavement structure in the embodiment of the present application is as follows: a plurality of longitudinal reinforcement blocks 3 are fixedly connected to the upper surface of a first roadbed slab 1, and a plurality of transverse reinforcement ribs 4 are fixedly connected to the interior of the longitudinal reinforcement blocks 3. The longitudinal reinforcement blocks 3 increase the longitudinal strength of the roadbed slab, and the transverse reinforcement ribs 4 further enhance the overall strength of the longitudinal reinforcement blocks 3, preventing them from deforming or breaking in the transverse direction. A second roadbed slab 5 is fixedly connected to the upper surface of a supporting steel bar column 2. The second roadbed slab 5 and the first roadbed slab 1 together form the foundation of the pavement structure, and can jointly bear the weight and stress of subsequent pavement layers. A high-modulus asphalt concrete layer 6 is provided on the upper surface of the second roadbed slab 5. Because the high-modulus asphalt concrete layer 6 has a high modulus, it has a high resistance to deformation. At the same time, its high strength helps to disperse stress, preventing excessive stress concentration in local areas of the road surface that may cause cracks. When the road surface is subjected to tensile stress, such as when tensile force is generated by temperature changes or vehicle loads, the glass fiber cloth and polyester glass fiber cloth can disperse the tensile force throughout the reinforcement layer 7 like a mesh structure. With its high tensile strength, the reinforcement layer 7 can withstand some of the tensile force and prevent the expansion of road cracks. The anti-cracking mortar has good adhesion and flexibility, and it can fill the tiny gaps that may appear in the road surface. The wear layer 9 is made of modified asphalt and is mainly used to withstand direct wear and friction from vehicle tires. The characteristics of modified asphalt give it good wear resistance. At the same time, the wear layer 9 can also resist erosion from natural factors such as rain and sunlight, protecting the underlying road surface structure, thereby extending the service life of the entire road surface structure.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
