Asphalt spreaders are used to spread the penetration oil, waterproof layer, and bonding layer of the bottom layer of high-grade highway asphalt pavement. It can also be used for the construction of county and township highway oil roads that implement layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.
Knowing how to properly operate and maintain the asphalt spreader can not only extend the service life of the equipment, but also ensure the smooth progress of the construction project.

So what should be paid attention to when working with an asphalt spreader?
Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreader, check the four thermal oil valves and the pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Test the asphalt pump and circulate for 5 minutes. If the pump head shell is hot, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not turn or make noise. In this case, the valve needs to be opened to continue heating the asphalt pump until it can operate normally. During the working process, the asphalt liquid must maintain an operating temperature of 160~180℃, and it cannot be filled too full (pay attention to the liquid level pointer during the injection of asphalt liquid, and check the tank mouth at any time). After the asphalt liquid is injected, the refueling port must be closed tightly to prevent the asphalt liquid from overflowing during transportation.
During use, the asphalt may not be pumped in. At this time, it is necessary to check whether the interface of the asphalt suction pipe is leaking. When the asphalt pump and pipeline are blocked by solidified asphalt, a blowtorch can be used for baking, and the pump must not be forced to turn. When baking, care should be taken to avoid directly baking the ball valve and rubber parts. Shandong Asphalt Spreader Manufacturer
When spraying asphalt, the car should be driven at a low speed. Do not step on the accelerator hard, otherwise it may cause damage to the clutch, asphalt pump and other components. If 6m wide asphalt is spread, pay attention to obstacles on both sides at any time to prevent collision with the spreading pipe. At the same time, the asphalt should be kept in a large circulation state until the spreading work is completed.
After each day's work is completed, any remaining asphalt must be returned to the asphalt pool, otherwise it will solidify in the tank and cannot be used next time.
