Description

Technical Field

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

[0002] Ruts are wheel indentations left by vehicles driving on the road surface. Ruts on asphalt pavements are one of the most important forms of pavement structure damage at present. The pavement structure of existing roads has poor anti-rutting performance. After long-term use, the anti-deformation ability becomes weaker, and the supporting and protective performance is reduced, affecting the comfort and safety of driving. For this reason, application number: 202221129179.7 discloses an anti-rutting pavement structure, which belongs to the technical field of road construction, and includes a base layer, a first reinforcing rib mesh is fixed above the base layer, a lower layer is fixed on the first reinforcing rib mesh, a buffer layer is arranged on the lower layer, a first bonding layer is fixed between the lower layer and the buffer layer, a second reinforcing rib mesh is arranged above the buffer layer, and an upper layer is fixed above the second reinforcing rib mesh; the pavement structure has the effect of improving the anti-rutting performance of the pavement and improving the comfort and safety of driving;

[0003] The anti-rutting pavement structure disclosed in the above patent can improve the anti-rutting performance of the pavement by buffering the pavement through the buffer layer and reinforcing the pavement with the reinforcement mesh, but it still has some shortcomings: 1. Its drainage effect is not ideal. Although the adhesive layer can prevent water from entering the buffer layer, the water accumulates on the upper layer for a long time, which will still damage the long surface layer of the pavement and further affect the pavement structure; 2. The buffer layer uses the elastic force of rubber strips and anti-rutting agents for buffering, but its elastic force is relatively small, which leads to an unsatisfactory buffering effect and the anti-rutting performance cannot be significantly improved; it cannot meet the use requirements. Based on the above situation, improvements are made, so we propose an anti-rutting pavement structure. Utility Model Content

[0030] The buffer layer 3 includes rubber sand 304, a plurality of elastic pressure-resistant balls 301 embedded in the rubber sand 304, a first elastic rubber strip 303 is bonded and fixed between two adjacent elastic pressure-resistant balls 301, a plurality of second elastic rubber strips 302 are bonded and fixed to the outer sides of the elastic pressure-resistant balls 301, the plurality of first elastic rubber strips 303 and the plurality of second elastic rubber strips 302 are all embedded in the rubber sand 304, and the combined elastic force of the rubber sand 304, the first elastic rubber strip 303 and the second elastic rubber strip 302 can be used to effectively buffer and unload the extrusion force of the pavement structure, thereby realizing unloading protection of the pavement structure, wherein the first elastic rubber strip 303, the elastic pressure-resistant balls 301 and the second elastic rubber strip 302 are all made of non-water-absorbing elastic materials;

[0031] The same drainage structure is arranged on the bonding layer 1, the base layer 100, the anti-rutting layer 5 and the asphalt layer 7, and the drainage structure is used for drainage operations, wherein the drainage structure includes a plurality of first water holes 11 opened on the bonding layer 1, a plurality of water grooves 9 are opened on the top of the base layer 100, the bottom inner wall of the water grooves 9 is inclined to the right, and the inner wall of the water grooves 9 is coated with a waterproof layer 10, a plurality of second water holes 4 are opened on the top of the anti-rutting layer 5, a plurality of third water holes 8 are opened on the top of the asphalt layer 7, and the third reinforcing rib net 701 is cross-connected with the plurality of third water holes 8; the utility model can effectively drain the pavement structure through the arrangement of a series of structures, effectively reduce the situation where rainwater soaking into the pavement structure causes damage to the pavement structure, improve the stability of the pavement structure, and cooperate with the effective buffering and reinforcement of the pavement to effectively protect the pavement, thereby effectively improving the anti-rutting performance of the pavement.

[0032] Working principle: When in use, the coarse gravel 603, the fine gravel and the rubber sand 304 all have good water permeability. In rainy weather, rainwater can enter the water channel 9 through the third water hole 8, the coarse gravel 603, the second water hole 4, the rubber sand 304, the fine gravel and the first water hole 11 in sequence, and be discharged into the municipal drainage system through the water channel 9. By draining the rainwater in time, the situation that the rainwater soaks into the pavement structure and causes damage to the pavement structure can be effectively reduced, thereby improving the stability of the pavement structure in use;

[0033] When the pavement structure is subjected to the extrusion pressure of the vehicle, under the extrusion pressure, the asphalt layer 7 and the second reinforcement layer 6 will be sequentially squeezed to the anti-rutting layer 5, and the anti-rutting layer 5 squeezes the rubber sand 304, the second elastic rubber strip 302 and the elastic anti-pressure ball 301 in the buffer layer 3. Under the extrusion pressure, the rubber sand 304, the second elastic rubber strip 302 and the elastic anti-pressure ball 301 are deformed, and at the same time, the two adjacent elastic anti-pressure balls 301 stretch the corresponding first elastic rubber strip 303.

By buffering and unloading the force with the combined elastic force, the unloading protection effect of the pavement structure is effectively improved.

[0034] By cross-coordinating the reinforcing ribs and the vertical reinforcing ribs in the first reinforcement layer 2 and the second reinforcement layer 6 and combining them with the setting of the third reinforcing rib network 701, the pavement structure can be further reinforced, and the strength of the pavement can be further improved. By effectively draining and dredging the pavement structure, coordinating reinforcement and effectively buffering and unloading force, the pavement can be effectively protected and its anti-rutting performance can be effectively improved.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
