    We need to prepare a lot of work when using modified asphalt equipment. What kind of work do we need to prepare? Next, let me briefly introduce the relevant knowledge points.
    1. Heat transfer oil heats and insulates the modified asphalt equipment and nozzle. After spraying, the asphalt pump and nozzle do not need to be cleaned with diesel. Use high-pressure air to press the asphalt in the pipeline and spray pipe back to the tank, and then blow the nozzle; use heat transfer oil to keep warm, so that the pipeline and nozzle are smooth and unobstructed. 2. Various asphalts can be spread: high-viscosity asphalt, hot asphalt, emulsified asphalt, etc.; the spreading width can be freely adjusted, each nozzle can be controlled separately, and the maximum spraying width is up to 6m. Flexible handheld spray guns can be used to spray asphalt on corners. 3. Excellent thermal insulation performance, average cooling ≤1-2℃/h. 4. Convenient loading and unloading function. In addition to filling asphalt from the asphalt tank port, hot asphalt can be sucked out by itself, and external asphalt can also be pumped and transferred. 5. The modified asphalt equipment is evenly spread, and the nozzle design can be used for triple overlapping spraying.

    What are the methods for repairing cracks in asphalt pavement? Asphalt pavement is a widely used pavement material in modern road construction, with high strength and durability. However, as time goes by and the frequency of use increases, cracks will inevitably appear in asphalt pavement. So, what are the methods for repairing cracks in asphalt pavement?
    What are the methods for repairing cracks in asphalt pavement?
    1. Oil filling repair method
    This repair method is mainly for smaller cracks or cracks. First, clean the damaged part, then soften the asphalt pavement with a liquefied gas tank, and then pour the thick asphalt into the cracks, and flatten it with a soldering iron, and then carry out normal pavement maintenance. The oil filling repair method is one of the methods for repairing cracks in asphalt pavement, and it is also one of the most commonly used repair methods.
    2. Emulsified asphalt seal repair method
    This method is mainly for minor cracks or loose cracks. Use a machine to apply a layer of emulsified asphalt on the ground, then sprinkle some stone chips, and finally roll it. This repair method can be constructed on rainy days, with a fast construction speed, and can handle minor crack problems.
    3. Cold-patch asphalt mixture repair method
    Cold-patch asphalt mixture is one of the asphalt pavement repair materials with good adhesion, wear resistance, and skid resistance. This material is suitable for the repair of various asphalt pavements. It is easy to use and can be quickly opened to traffic after repair, reducing construction time. The color of the cold-patch asphalt mixture is also very different from the original pavement, which can be clearly distinguished and convenient for construction operations.

    Asphalt spreader is used to spread the penetration oil, waterproof layer and bonding layer of the bottom layer of asphalt pavement of high-grade highway. It can also be used for the construction of county and township highway oil roads with 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 enable the construction project to proceed smoothly. So what problems should the asphalt spreader pay attention to when working? The technicians of Gaoyuan Road Construction Machinery Equipment Co., Ltd. give you tips:
    1). 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 be kept at a working 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 filling port must be closed tightly to prevent the asphalt liquid from overflowing during transportation.
    2). During use, 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.
    3). 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 the work is completed every day, if there is any remaining asphalt, it must be returned to the asphalt pool, otherwise it will solidify in the tank and cannot work next time.
    4). In addition, the emulsifier must also pay attention to daily maintenance:
    1. The emulsifier and delivery pump and other motors, agitators, and valves should be maintained daily.
    2. The emulsifier should be cleaned after work every day.
    3. The speed regulating pump used to control the flow should be regularly tested for accuracy, and adjusted and maintained in time. The asphalt emulsifier should regularly check the matching clearance between its stator and rotor. When the minimum clearance specified by the machine cannot be reached, the stator and rotor should be replaced.
    4. If the equipment is out of use for a long time, the liquid in the tank and pipeline should be emptied (the emulsifier aqueous solution should not be stored for a long time), the hole covers should be tightly closed, kept clean, and the running parts should be filled with lubricating oil. When it is used for the first time or when it is used again after a long period of inactivity, the rust in the tank should be removed, and the water filter should be cleaned regularly.
    5. Regularly check whether the terminal in the electric control cabinet is loose, whether the wires are worn during shipment, and remove dust to avoid damage to the machine parts. The frequency converter is a precision instrument. Please refer to the instruction manual for specific use and maintenance.
    6. There is a heat transfer oil coil in the emulsifier water solution heating stirring tank. When injecting cold water into the water tank, the heat transfer oil switch should be turned off first, and then the switch should be turned on to heat after adding the required amount of water. Pouring cold water directly into the high-temperature heat transfer oil pipeline can easily cause the weld to crack.

    1. Different production processes
    Emulsified asphalt and asphalt are both extracted from petroleum, but their production processes are different. Asphalt is separated from crude oil by high-temperature treatment, and then processed through a series of complex processing processes such as distillation and fluidized hydrogenation. Emulsified asphalt, on the other hand, is made by adding an emulsifier, mechanical shearing or ultrasonic “emulsification” reaction, dispersing oil and water to form an emulsion, and then adding an appropriate amount of acid catalyst.
    2. Different usage scenarios
    Asphalt is suitable for paving in different places such as roads, bridges, airport runways, and parking lots. Emulsified asphalt is particularly suitable for use under more stringent conditions such as deep road repair and bridge deck waterproofing. Because emulsified asphalt produced by emulsification technology has better performance and can better adapt to complex usage environments.
    3. Different characteristics
    Asphalt is a black, viscous substance with fluffy fibers, a high melting point, high hardness, and easy aging. In comparison, emulsified asphalt is lighter in color, light gray or milky white, with moderate viscosity and uniformity, good adhesion, good water and weather resistance, and not easy to age.
    4. Different use effects
    Although asphalt works well on the road surface, it also has certain difficulties in construction and maintenance. Emulsified asphalt is more convenient to use and can be easily mixed with other materials during construction, so it is widely popular and has better use effects.
    In summary, there are obvious differences between emulsified asphalt and asphalt in production process, usage scenarios, characteristics, and use effects, and appropriate materials need to be selected according to different needs.
