With the continuous development of world highway transportation, how to make asphalt pavement not only ensure road performance, but also speed up progress and save costs has always been a concern of highway experts. The asphalt synchronous chip seal construction technology has solved the problem of the previous slurry The sealing layer has many shortcomings such as strict requirements on aggregates, construction being affected by the environment, difficulty in quality control, and high cost. The introduction of this construction technology is not only easy to improve the construction quality and save costs, but also has a faster construction speed than the slurry sealing layer. At the same time, because this technology has the characteristics of simple construction and easy quality control, it is very necessary to develop asphalt synchronous chip sealing technology in various provinces in the country.

The synchronous chip sealing truck is mainly used for the gravel sealing process in road surface, bridge deck waterproofing and lower sealing layer. Synchronous chip seal truck is a special equipment that can synchronize the spreading of asphalt binder and stone, so that the asphalt binder and stone can have the fullest surface contact in a short period of time and achieve the maximum adhesion between them. , especially suitable for spreading asphalt binders that require the use of modified bitumen or rubber bitumen.

Road safety construction is not only responsible for oneself, but also for the lives of others. Safety issues are more important than anything else. We introduce to you the safety instructions for the construction of asphalt synchronous sealing vehicles:
1. Before operation, all parts of the car, each valve in the piping system, each nozzle and other working devices should be inspected. Only if there are no faults can they be used normally.
2. After checking that there is no fault in the synchronous sealing vehicle, drive the vehicle under the filling pipe, first put all the valves in the closed position, open the small filling cap on the top of the tank, put the filling pipe in, start filling asphalt, and refuel When finished, close the small oil cap tightly. The asphalt added must meet the temperature requirements and cannot be filled too full.
3. After the synchronous sealing truck is filled with asphalt and gravel, start slowly and drive to the construction site at a medium speed. During transportation, no one is allowed to stand on each platform; the power take-off must be out of gear, and the burner is prohibited from being used while driving; all valves must be closed.
4. After being transported to the construction site, if the temperature of the asphalt in the tank of the synchronous sealing truck cannot meet the spraying requirements, the asphalt must be heated. During the asphalt heating process, the asphalt pump can be rotated to achieve uniform temperature rise.
5. After the asphalt in the tank reaches the spraying requirements, drive the synchronous sealing vehicle until the rear nozzle is about 1.5 to 2m away from the starting point of the operation and stop. According to the construction requirements, you can choose automatic spraying controlled by the front desk and manual spraying controlled by the background. During operation, no one is allowed to stand on the middle platform, the vehicle must drive at a constant speed, and it is prohibited to step on the accelerator.
6. When the operation is completed or the construction site is changed midway, the filter, asphalt pump, pipes and nozzles must be cleaned.
7. After the cleaning operation of the last train of the day is completed, the following closing operations must be completed.
