Description

Technical Field

[0001] The utility model relates to the technical field of pavement maintenance, in particular to a composite sealing layer used for asphalt pavement maintenance. Background Art

[0002] Composite seals for asphalt pavement maintenance are a technology used to enhance and extend the life of asphalt pavement. This seal typically includes a combination of multiple materials designed to provide additional protection, waterproofing, crack resistance and wear resistance, including fiber reinforcements, adding fiber materials (such as polymer fibers) to the seal to improve the pavement's crack resistance. These fibers can effectively prevent the expansion of cracks, thereby extending the life of the pavement, as well as the combination of modified asphalt and microscopic fillers in the seal.

[0003] A crack-resistant rubber asphalt composite seal layer disclosed in the Chinese utility model patent application disclosure specification CN206736657U includes a composite seal layer laid on a concrete pavement and a micro-surfacing located on the upper part of the composite seal layer; it is characterized in that: the composite seal layer includes at least two layers of single-particle crushed stone layers; and the particle size of the upper crushed stone layer is not larger than the particle size of the lower crushed stone layer; and a rubber asphalt seal layer is provided between two adjacent layers of crushed stone layers; and a rubber asphalt seal layer is provided between the bottom crushed stone layer and the concrete pavement. The composite seal layer structure of the utility model has strong adhesion to the original pavement, good embedded structure, and good structural stability. The crack resistance of the AR-CS structure is improved by increasing the amount of rubber asphalt and the thickness of the crushed stone seal layer. The road performance of the micro-surfacing of the surface layer is improved by material selection and process optimization. This embodiment uses high-viscosity emulsified asphalt as a binder to improve the durability of the micro-surfacing.

[0004] However, the utility model lacks liquefaction repair capability, and cannot achieve the function of using sand, gravel and asphalt to flow and repair various ground damages only by heating. It cannot avoid the situation where the transmission repair method is difficult to repair small or deep cracks. Secondly, the utility model lacks rapid transportation and unloading capabilities for laying during construction, and cannot achieve the function of transporting the sealing layer in the form of finished products and quickly using it to improve maintenance efficiency. The traditional sealing layer may need to be laid layer by layer, which consumes manpower and material resources. Utility Model Content

[0005] The utility model aims to provide a composite seal layer for asphalt pavement maintenance to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Preferably, an I-shaped frame is wound around the bottom of the watch case, and binding ropes are fixedly provided at both ends of the I-shaped frame.

[0014] Preferably, a rotating shaft is fixedly arranged inside the I-shaped frame, and a rotating disk is fixedly arranged at one end of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. This composite seal layer for asphalt pavement maintenance is provided with a heat-conducting component and a repairing component. When used by a worker, the seal layer is first laid on the road section that needs maintenance, and the case is heated by a heating device. The heat is transferred to the flexible frame through the heat-conducting soft plate. The flexible frame heats the hot-melt film and the hot-melt asphalt. At this time, the hot-melt film ruptures, and the hot-melt asphalt flows into the damaged part of the ground in liquid form. At the same time, the sand and gravel filler flows into the damaged road surface along with the hot-melt asphalt along the leak, thereby achieving the effect of sand and gravel asphalt flowing to repair various ground damages only by heating, avoiding the situation where the transmission repair method is difficult to repair small or deep cracks.

[0017] 2. This composite seal layer for asphalt pavement maintenance is provided with a case, an extension component, a reinforcement layer, an I-frame, a turntable, a binding rope, a thermally conductive soft plate, and a flexible frame. When the staff uses it, since the asphalt filler, compression rubber, high-strength fiber, thermally conductive soft plate, flexible frame, and reinforcement layer are all flexible materials, the whole is still flexible after production. The case is wrapped around the I-frame and trapped with binding ropes for transportation. When it reaches the designated maintenance location, the turntable drives the I-frame to rotate, and the seal layer is extended into a plane, thereby realizing the seal layer being transported in the form of a finished product and being quickly used to improve the maintenance efficiency, avoiding the situation where the traditional seal layer needs to be laid layer by layer, which consumes manpower and material resources.
