As the core part of the entire asphalt mixing plant, the design of the control system has been introduced to you. The next two chapters are about its daily maintenance. Don't ignore this aspect. Good maintenance will also help the control system function, thereby promoting the use of the asphalt mixing plant.

The asphalt spreading truck must check its driving speed when carrying out asphalt penetration work, and feed back the speed signal to the controller to determine the amount of asphalt spreading. When the current speed is high, the controller controls the asphalt pump output to increase, and when the speed slows down, the controller controls the asphalt pump output to decrease to make the asphalt permeable layer uniform and in line with the construction requirements of the asphalt permeable layer project.

The emulsion bitumen produced by asphalt mixing equipment is very versatile, but precipitation occurs during storage. Is this normal? What causes this phenomenon?

When purchasing an asphalt mixing plant, the manufacturer's technical staff made important reminders about the lubrication requirements of the equipment, including the lubrication of each component, which cannot be ignored. In this regard, users have also formulated strict standards to regulate them, as follows:

(1) The essence of the synchronous gravel seal is an ultra-thin asphalt gravel surface treatment layer bonded by a certain thickness of asphalt film (1~2mm). Its overall mechanical characteristics are flexible, which can increase the crack resistance of the pavement and heal the pavement. It can reduce cracks in the road surface, reduce reflective cracks on the road surface, improve the anti-seepage performance of the road surface, and maintain waterproof properties for a long time. It can be used for road maintenance to extend the service life of the road surface to more than 10 years. If polymer modified binder is used, the effect will be better.

Asphalt spreading trucks can be used for the construction of upper and lower seals, permeable layers, asphalt surface treatment, asphalt penetration pavement, fog seals and other projects on the road surface. They can also be used for the transportation of liquid asphalt or other heavy oil.
