Description

Technical Field

[0001] The invention relates to the technical field of road engineering, in particular to an asphalt road structure at a junction of a basement top plate and a non-top plate and a construction method. Background Art

[0002] In the field of road engineering, especially the road construction involving the junction of the basement top slab and the non-top slab, there is often a thorny problem: cracks and cracks caused by uneven foundation settlement. This situation is particularly common in asphalt roads, whose width covers the junction of the basement top slab area and the natural foundation road surface (non-top slab area).

[0003] Specifically, the basement roof area is usually filled and reinforced with backfill soil to form a stable road foundation. However, the adjacent non-roof area, the natural foundation pavement, is built directly on natural soil, and its geological conditions and bearing capacity may be significantly different from the backfill soil. This inconsistency of materials on both sides can easily lead to uneven settlement of the foundation at the junction under the long-term vehicle load and natural environmental factors of the road.

[0004] Uneven settlement can cause a series of problems, the most notable of which is the appearance of cracks and fissures on asphalt road pavement. These cracks not only affect the appearance and driving comfort of the road, but more importantly, they reduce the road's bearing capacity and durability, and may even threaten driving safety. Therefore, how to solve the problem of uneven settlement of asphalt roads at the junction of the basement top plate and the non-top plate has become a technical problem that needs to be solved urgently in the current road engineering field.

[0005] Although some solutions have been proposed in the prior art to solve this problem, they often have the disadvantages of complex construction, high cost or poor effect. Therefore, the present invention aims to provide a more effective, economical and easy-to-implement road structure and construction method thereof to completely solve the above quality problems. Summary of the invention

[0006] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide an asphalt road structure and a construction method at the junction of a basement top plate and a non-top plate.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the asphalt road structure at the junction of the basement top plate and the non-top plate includes:

[0008] Stabilized base layer, shear layer, penetration layer asphalt, load-bearing layer, tack layer asphalt, pavement granular layer, first force transmission layer, second force transmission layer;

[0009] The stable base is arranged above the junction of the basement roof and the non-roof; the shear-resistant layer covers the upper surface of the stable base, and the shear-resistant layer is provided with steps, and the steps are parallel to the length direction of the asphalt road; the penetration layer asphalt is flipped over the upper surface of the shear-resistant layer, the load-bearing layer covers the upper surface of the penetration layer asphalt, and the upper surface of the load-bearing layer remains horizontal; the first force transmission layer and the second force transmission layer are respectively arranged on both sides of the shear-resistant layer, the penetration layer asphalt and the load-bearing layer, and the first force transmission layer is arranged above the roof, the first force transmission layer is provided with multiple groups of first force transmission rods in the horizontal direction, and the first force transmission rods are inserted into the steps, and the second force transmission layer is provided with multiple groups of second force transmission rods in the horizontal direction, and the second force transmission rods are inserted into the load-bearing layer; the tack layer asphalt covers the upper surface of the load-bearing layer, and the pavement granular layer covers above the tack layer asphalt.

[0010] Main working principle: First, the stable base is set above the junction between the basement top plate and the non-top plate. The main function of this layer is to fill and support, ensuring that the foundation of the entire road structure is stable and can evenly distribute the weight and load of the upper structure. The shear layer covers the upper surface of the stable base, and its design has steps that are parallel to the length direction of the asphalt road. The main function of the shear layer is to enhance the shear resistance of the structure and prevent shear failure caused by uneven settlement of the foundation or load changes. The design of the steps helps to further increase the stability of the structure and provides a basis for the subsequent setting of the force transfer layer. The permeable asphalt covers the upper surface of the shear layer, and its main function is to penetrate and bond to the shear layer below to form a continuous and tight interface. This helps to enhance the integrity and durability of the road structure. The load-bearing layer covers the upper surface of the permeable asphalt and keeps its upper surface level. The load-bearing layer is the main load-bearing layer of the road structure, which can withstand vehicle loads and pedestrian loads and transfer them evenly to the shear layer below. The first force transfer layer and the second force transfer layer are respectively set on both sides of the shear layer, the permeable asphalt and the load-bearing layer. The first force-transfer layer is located above the top plate, and multiple groups of first force-transfer rods are arranged in the horizontal direction, and these force-transfer rods are inserted into the steps of the shear layer. The second force-transfer layer also has multiple groups of second force-transfer rods arranged in the horizontal direction, and these force-transfer rods are inserted into the load-bearing layer. The main function of the force-transfer layer is to transfer and disperse the load, ensuring that the load can be evenly and effectively transferred to the entire road structure, reducing the damage caused by excessive local load. The tack layer asphalt covers the upper surface of the load-bearing layer, and its main function is to bond and fix the pavement granular layer above. The pavement granular layer is the surface layer of the road structure, which directly bears the wear and impact of vehicles and pedestrians. The design of these two layers helps to enhance the wear resistance and skid resistance of the road, and improve driving safety and comfort.

[0011] In summary, the asphalt road structure at the junction of the basement top plate and the non-top plate ensures the stability and durability of the road structure through reasonable layer design and force transmission mechanism. The layers work closely together to jointly bear and disperse the load, reducing the risk of damage caused by uneven foundation settlement or load changes.

[0022] Preferably, the height of the step is not less than 100 mm.

[0023] Preferably, the step extends along to the periphery of the top plate.

[0024] The construction method for the junction between the basement top plate and the non-top plate of the asphalt road structure based on any one of the above-mentioned junctions between the basement top plate and the non-top plate comprises the following steps:

First, the stable base 1 is set above the junction between the basement top plate and the non-top plate. The main function of this layer is to fill and support, to ensure that the foundation of the entire road structure is stable, and to evenly distribute the weight and load of the upper structure. The shear layer 2 covers the upper surface of the stable base 1, and is designed with steps 20, which are parallel to the length direction of the asphalt road. The main function of the shear layer 2 is to enhance the shear resistance of the structure and prevent shear failure caused by uneven settlement of the foundation or load changes. The design of the steps 20 helps to further increase the stability of the structure and provides a basis for the subsequent setting of the force-transfer layer. The permeable asphalt 3 covers the upper surface of the shear layer 2, and its main function is to penetrate and bond to the shear layer 2 below to form a continuous and tight interface. This helps to enhance the integrity and durability of the road structure. The bearing layer 4 covers the upper surface of the permeable asphalt 3 and keeps its upper surface level. The load-bearing layer 4 is the main load-bearing layer of the road structure, which can bear vehicle loads and pedestrian loads and transfer them evenly to the shear layer 2 below. The first force-transfer layer 7 and the second force-transfer layer 8 are respectively arranged on both sides of the shear layer 2, the penetration layer asphalt 3 and the load-bearing layer 4. The first force-transfer layer 7 is located above the top plate, and multiple groups of first force-transfer rods 70 are arranged in the horizontal direction, and these force-transfer rods are inserted into the steps 20 of the shear layer 2. The second force-transfer layer 8 is also arranged in the horizontal direction. Multiple groups of second force-transfer rods 80 are inserted into the load-bearing layer 4. The main function of the force-transfer layer is to transfer and disperse the load, ensure that the load can be evenly and effectively transferred to the entire road structure, and reduce the damage caused by excessive local loads. The tack layer asphalt 5 covers the upper surface of the load-bearing layer 4, and its main function is to bond and fix the road granular layer 6 above. The road granular layer 6 is the surface layer of the road structure, which directly bears the wear and impact of vehicles and pedestrians. The design of these two layers helps to enhance the wear resistance and skid resistance of the road, and improve driving safety and comfort.

[0045] In summary, the asphalt road structure at the junction of the basement top plate and the non-top plate ensures the stability and durability of the road structure through reasonable layer design and force transmission mechanism. The layers work closely together to jointly bear and disperse the load, reducing the risk of damage caused by uneven foundation settlement or load changes.

[0046] In some optional embodiments, a first sleeve 71 and a second sleeve 81 are respectively provided in the first force transmission layer 7 and the second force transmission layer 8. These sleeves are provided at one end of the force transmission rod inserted into the shear layer 2, and play a role in fixing and protecting the force transmission rod, preventing the first force transmission rod 70 and the second force transmission rod 80 from being broken during deformation in the concrete, thereby further enhancing the stability and durability of the road structure, thereby improving the overall stability and shear resistance of the road structure at the joint.

[0047] In some optional embodiments, a first filling groove 72, a first plain concrete layer 73, a second filling groove 82, and a second plain concrete layer 83 are respectively provided in the first force transmission layer 7 and the second force transmission layer 8. The design of these filling grooves and plain concrete layers enables the force transmission rod to be better combined with the load-bearing layer 4, thereby improving the force transmission efficiency. At the same time, the plain concrete layer also plays a role in strengthening the connection between the force transmission rod and the load-bearing layer 4, further improving the overall stability of the road structure.

[0048] In some optional embodiments, asphalt hemp is provided in both the first filling groove 72 and the second filling groove 82. The asphalt hemp is provided under the force transmission rod, which plays the role of waterproofing, isolation and buffering, prevents the erosion and damage of the force transmission rod by moisture and impurities, and reduces the friction and wear of the force transmission rod during the force transmission process.

[0049] In some optional embodiments, a first foam rod 74 and a second foam rod 84 are respectively provided in the first filling groove 72 and the second filling groove 82, and polyurethane foam fillers are filled above the foam rods. The design of these foam rods and fillers plays a role in further fixing the force transmission rod, strengthening the connection between the force transmission layer and the load-bearing layer 4, and improving the overall rigidity and earthquake resistance of the road structure.

[0050] In some optional embodiments, the height of the step 20 is not less than 100 mm. This design ensures that the step 20 plays an effective anti-shear role in the anti-shear layer 2, while avoiding the adverse effects of the step 20 being too high or too low on the stability of the road structure.

[0051] In some optional embodiments, the step 20 extends along the periphery of the top plate. This design enables the step 20 to be better combined with the top plate, thereby enhancing the integrity and stability of the road structure at the joint.

[0052] In summary, this specific embodiment significantly improves the stability and durability of the asphalt road structure at the junction of the basement roof and the non-roof through multi-level and multi-faceted structural design, reduces cracks and fissures caused by uneven foundation settlement or load changes, optimizes load distribution, and extends the service life of the road. At the same time, these designs also improve the seismic resistance and waterproof performance of the road structure, providing a strong guarantee for its application in actual engineering.
