Background
In recent years, with the rapid development of the economy of China, the transportation industry enters the rapid development era. However, municipal road construction in China starts relatively late, technical strength is relatively weak, and under the comprehensive action of traffic load and natural environment, early-stage damage phenomena such as cracks, settlement, rutting, oil spill and the like appear in advance only a few years after a road surface (particularly an asphalt road surface) is put into operation, so that the service performance of the road surface is greatly reduced. The early damage of the road surface is developed into the biggest problem in road construction in China, and maintenance and repair work is urgent and is developed into one of the important work carried out by the transportation department.
In the middle and later stages of the 90 s of the 20 th century, the advanced concept and technology of preventive maintenance are introduced from Shanghai. The preventive maintenance technology is essentially a mandatory maintenance measure, when the pavement structure does not generate diseases or the disease phenomenon just occurs, maintenance is carried out in advance to kill the diseases in the cradle, and the initiative of maintenance is mastered so as to delay the damage of the pavement. At that time, the preventive maintenance technologies introduced in Shanghai include slurry seal, micro surfacing and the like, and now with the rapid development of science and technology, the preventive maintenance technologies are continuously updated, and a plurality of new technologies, new processes and preventive maintenance technologies of new materials are generated. The current technology of asphalt macadam seal is simple and widely used.
The rubber asphalt macadam seal is a thin seal formed by rolling and spreading a layer of single-particle-size macadam immediately after a base layer or a surface layer is sprayed with a layer of rubber asphalt, can seal fine cracks of the base layer or the surface layer and prevent water from invading a pavement, meanwhile, the rubber asphalt has excellent elasticity, and compared with a common macadam seal, the rubber asphalt seal mainly has the advantages of good waterproof performance, strong radiation crack resistance, good durability and the like, and is generally widely used as a waterproof layer and a stress absorption layer of the pavement.
At present, a construction technology of a high-elasticity rubber asphalt composite gravel seal is provided, the composite seal is composed of a multi-layer synchronous gravel seal structure, the gravel particle size is reduced from bottom to top in sequence, the coarse particle size is used as a support, the fine particle size is used as a caulking material and is embedded into a gap of the coarse particle size to form a good embedding and extruding type structure, the composite gravel seal can be used as a newly-built or reconstructed pavement surface layer to directly bear traffic, the traffic can be opened in the same day, the composite gravel seal has excellent anti-reflection crack performance, the manufacturing cost is low, the construction period is short, and the composite gravel seal gradually becomes a main method for old road reconstruction.
However, at present, no corresponding composite gravel seal layer paving device exists, a plurality of synchronous gravel seal layer vehicles are often adopted for layered paving, and the vehicles cannot be integrally formed, so that the construction cost is high, and the problems that the construction machinery is difficult to dispatch, the asphalt temperature loss is large, and the construction effect is poor exist.
