Description

Technical Field

[0001] This application relates to the field of road construction, and in particular to a carpet-type rubber pavement. Background Technology

[0002] Currently, over 80% of highways in my country are semi-rigid base asphalt pavements. While semi-rigid base asphalt pavements have advantages such as good slab-like structure and strong load-bearing capacity, they also have inherent drawbacks such as thermal shrinkage cracking, which reduces the service life of asphalt pavements. Flexible base pavements have good performance, but their cost is about 65% higher than that of semi-rigid base asphalt pavements. The maintenance of semi-rigid base asphalt pavements generates a large amount of waste asphalt mixture, and improper disposal can cause serious environmental pollution and resource waste.

[0003] Existing traditional asphalt pavement is generally composed of two or three layers of AC asphalt mixture. With increasing traffic volume and severe overloading, the anti-skid, drainage, and noise reduction properties of traditional pavement structures deteriorate rapidly after a period of use, leading to serious pavement damage and numerous safety hazards. Therefore, road repair and maintenance are necessary.

[0004] The existing technical solutions mentioned above have the following drawbacks: existing road repair and maintenance require on-site material mixing, paving and other processes, and the road restrictions can only be lifted after the material properties have stabilized, resulting in long road maintenance cycles and low maintenance efficiency. Utility Model Content

[0005] This application provides a carpet-type rubber pavement in order to reduce the maintenance cycle and improve the maintenance efficiency of the road surface.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A blanket-type rubber pavement includes a rubber base layer, an adhesive layer, and a sealing layer. The rubber base layer is laid horizontally on the working surface. An adhesive layer is provided at the bottom end of the rubber base layer and is fixedly connected to the rubber base layer. The adhesive layer is used to bond the rubber base layer to the working surface. The sealing layer is located on the side of the adhesive layer away from the rubber base layer. When the sealing layer is bonded to the adhesive layer, it is used for the rubber pavement to be transported in rolls. When the rubber base layer is used, the sealing layer is peeled off.

[0008] Furthermore, a wear-resistant layer is provided on the side of the rubber base layer away from the adhesive layer, and the wear-resistant layer is fixed to the rubber base layer.

[0009] Furthermore, an upper buffer layer is provided between the wear-resistant layer and the rubber base layer, and the upper buffer layer is fixed to both the wear-resistant layer and the rubber base layer.

[0010] Furthermore, a waterproof layer is provided between the upper buffer layer and the wear-resistant layer, and the waterproof layer is fixed to both the wear-resistant layer and the upper buffer layer.

[0011] Further, a lower buffer layer is arranged between the rubber base layer and the adhesive layer, and the lower buffer layer is fixed with the rubber base layer and the adhesive layer.

[0012] Further, a connecting piece is arranged between the rubber base layer and the upper buffer layer and the lower buffer layer, and the upper buffer layer and the lower buffer layer are provided with a plug-in slot, one end of the connecting piece is fixedly connected with the rubber base layer, and the other end is plugged into the plug-in slot.

[0013] Further, the end of the connecting piece away from the rubber base layer is provided in a semispherical shape, and the plug-in slot is provided in a necked slot matching the semispherical shape.

[0014] Further, the rubber base layer comprises an upper base layer and a hard base layer, the upper base layer is close to the upper buffer layer, the hard base layer is close to the lower buffer layer, the upper base layer and the hard base layer are fixedly connected, the hard base layer is provided with a metal mesh, and the hard base layer is used to enhance the folding resistance of the rubber base layer.

[0015] In summary, the application has the following technical effects:

[0016] 1. By arranging the rubber pavement comprising the rubber base layer, the adhesive layer and the plastic sealing layer, the adhesive layer is closed by the plastic sealing layer, so that the rubber pavement is rolled into a coiled material after being processed in the processing factory, and then the coiled material is transported to the construction site, when the rubber pavement is used, the plastic sealing layer is opened to expose the adhesive layer, and then the rubber pavement is laid on the working surface like a carpet, the rubber base layer is quickly laid and fixed on the working surface by the adhesive layer, the repair and maintenance of the road are quickly completed, the maintenance period of the road is reduced, and the maintenance efficiency of the road is improved.

[0017] 2. By arranging the wear-resistant layer and the waterproof layer, the waterproof performance of the rubber pavement is improved by the waterproof layer, the damage of the rubber pavement caused by water penetration and then icing is reduced, and then the wear-resistant layer is laid to enhance the wear-resistant performance of the rubber pavement, thereby prolonging the service life of the rubber pavement.

[0018] 3. By arranging the upper buffer layer and the lower buffer layer, the pressure borne by the rubber base layer is buffered by the buffer layer, the bending of the rubber base layer when stressed is reduced, and fatigue damage of the rubber base layer is avoided as much as possible.
