During the long-term use of asphalt pavement, due to multiple impacts of repeated rolling of various heavy-load vehicles and environmental and other factors, the physical or chemical changes of asphalt pavement materials may be caused. After a long period of use, cracks, subsidence, peeling and numbness, and various other damages will occur. Failure to repair the vehicle in time will affect the normal driving of the vehicle, and it will also result in the occurrence of a larger area of ​​damage. Asphalt pavement maintenance vehicles are multifunctional special-purpose engineering vehicles used for daily maintenance of asphalt pavement, and are important supporting maintenance machinery for highway maintenance.
Asphalt road maintenance vehicles are machines for the construction of black roads. They are the main equipment for the construction of highways, urban roads, major airports and port terminals. In the method of asphalt penetration and the treatment of asphalt pavement, when transporting and spraying liquid asphalt (including hot asphalt and emulsified asphalt), asphalt pavement maintenance vehicles can be used for construction when building asphalt pavement or maintaining asphalt. In addition, it can also provide asphalt binders for loose soil in situ, and build asphalt stabilized soil pavement or pavement base.
The construction of a bituminous sprinkler for the adhesive layer of the waterproof layer of the bottom layer of the asphalt pavement of the high-grade highway, and the asphalt covering and spraying in the highway maintenance can also be used to implement the anti-jamming capability of the layer paving equipment.
Intelligent asphalt pavement maintenance vehicles are used to build high-grade highway asphalt pavement bottom layer through oil, waterproof layer, adhesive layer spray. Can be sprinkled with high-viscosity asphalt, heavy-duty asphalt, modified emulsified asphalt, and emulsified asphalt. For the county and township roads, the layered paving process intelligent asphalt pavement maintenance vehicles can also be constructed. Automobile chassis, asphalt tanks, asphalt irrigation systems, thermal oil heating systems, hydraulic systems, combustion systems, control systems, pneumatic systems, etc., form the main body of this model.
work process:
1. The frying oil sand working process is lifted by a lifting machine and rolled into a rolling drying drum. After being heated and dried, the stone powder in the sand is blown by a blower. After the sand is dried to a specified temperature, the sand is delivered to the forced mixer and Asphalt is fully stirred and oil sands can be produced.
2. The asphalt spray working process will heat the asphalt to the specified temperature and then pump it through the asphalt pump. Spray the asphalt on the pavement to be repaired by hand-held spray gun.
