Description
Technical Field
The invention belongs to the technical field of engineering mechanical equipment and construction methods required by road and airport construction, maintenance and repair and other pavement operations. In particular to a slurry seal vehicle and micro-surfacing paving equipment.
Background
Micro surfacing and slurry sealing technologies have become an important component in road construction and pavement maintenance and repair projects. The micro-surfacing and slurry sealing is that a slurry mixture is formed by continuously mixing stone grains or sand, stone powder, cement, water and additives with certain gradation with emulsified asphalt (high molecular polymer modified emulsified asphalt), then the mixture is quickly and uniformly spread on the road surface to be constructed, and then the processes of emulsion breaking, water separation, evaporation, solidification, forming and the like are carried out to form a sealing or rutting filler. The method can be used for performing preventive maintenance, early maintenance, rut filling and repairing, pavement appearance improvement and the like on the surface function of the road. The adhesive has the functions of adhesion, water resistance and the like in the lower sealing layer in the construction of the road surface and the airport runway. Effectively improves the road service performance and prolongs the service life of the road. Micro-surfacing, slurry seal paving equipment and a construction technical method have important influence on construction quality and performance.
A great deal of research at home and abroad shows that the improper treatment between pavement layers is one of the important reasons for causing the quality problem of micro-surfacing or slurry sealing pavement, because the original road surface layer and the slurry sealing or micro-surfacing surface layer are two materials and processes with different structures, if the interlayer binding force is insufficient, the load caused by road running is added alternately in four seasons in the natural environment, particularly heavy load and overload, and the extrusion and shear deformation between the layers are continuously accumulated, so that the problems of premature falling, cracks, rough surfaces, pushing, uneven pavement and the like of the slurry sealing or micro-surfacing pavement are caused.
In addition, the existing equipment design scheme shows that: the effective power of the equipment is limited, and the functionality is single, so that the prior micro-surfacing pretreatment process for the pavement needs to be carried out in advance by using separate equipment. Therefore, the mineral aggregate which is scattered in the construction process can not be cleaned in time, and the sliding shoe of the paving device is inevitably lifted and out of control to slide, so that the quality problems of material leakage, material running and the like can be caused, and the paving quality and effect are directly influenced.
Particularly, the method for performing a pretreatment process on the road surface before the existing micro-surfacing construction operation generally adopts simple water spraying to play a role in wetting and cooling; before construction, the road surface is pretreated by adopting non-special cleaning equipment and a shoulder-back portable blower alone. The engineering practice reflects: the technical method has very limited cleaning effect on road surfaces of deposited ash layers, asphalt oxide layers, unstable materials and the like of the original road surface; the watering amount is not scientifically and reasonably controlled, and redundant accumulated water is easily formed on the road surface and is not drained in time; obviously, the requirement of construction process design cannot be met. Therefore, the traditional micro-surfacing pretreatment construction process method is very labor-consuming, time-consuming, low in construction efficiency, large in occupied equipment and manpower, high in construction cost, uneconomical and not suitable for carbon peak reaching and carbon neutralization.
The above problems have not been solved effectively.

Therefore, the quality problems of material leakage, material leakage and the like caused by the fact that the sliding shoes of the paving device are lifted smoothly and slide out of control due to the fact that the sliding shoes of the paving device are caused by particle materials (such as scattered mineral materials during construction operation, residues left after milling and finishing the road surface and the like) on the road surface can be effectively solved; secondly, deposited ash layers, asphalt oxide layers, unstable materials and the like on the original pavement can be effectively removed; the water is sprayed again to moisten and cool the road surface, and the construction is carried out in high-temperature weather, so that the temperature of the ground road surface is reduced, the humidity of the road surface is improved, the demulsification speed is slowed down, and the bonding strength is improved.
