What preparations should be made before using the modified emulsified asphalt equipment?

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of modified asphalt equipment in order to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Gaoyuan Road Construction will explain it in detail:
1. Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be suspended to ensure that the machine does not move around during operation.
2. Check regularly whether the mixer blades are deformed and whether the screws are loose.
3. Check whether the running direction of the mixing barrel is consistent with the arrow. If not, please replace the positive and negative poles of the wiring.
4. Before powering on, check for empty vehicle trial operation, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, you should stop and check.
5. If the machine is stopped for more than one hour after the asphalt mixing is completed, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing and even rusting of the pages and other links.

    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.
    The above are the relevant knowledge points of modified asphalt equipment. I hope the above content can be helpful to everyone. Thank you for your viewing and support. More information will be sorted out for you later. Please pay attention to our website updates.

    Emulsified modified asphalt equipment is classified according to the production process and can be divided into three types: intermittent emulsified modified asphalt equipment, semi-continuous emulsified modified asphalt equipment, and continuous emulsified modified asphalt equipment. During the production of emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are blended in a soap mixing tank, and then pumped into the asphalt into the colloid mill. After a can of soap is used up, the soap is redispensed, and then the production of the next can is completed.
    The emulsified modified asphalt equipment mentioned here includes hot water pumps and circulation pumps. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Pay attention to the sewage outlet at the bottom of the emulsified modified asphalt equipment pump. The water in the water tank is released through the filter valve. Some emulsified modified asphalt equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange bolts at the bottom. There are basically two methods of moisturizing emulsion pumps for emulsified modified asphalt equipment on the market, gear oil pumps or centrifugal water pumps. The gear oil pump can only drain the liquid in the pump through the connecting flange of the pipeline. The centrifugal water pump carries out sewage treatment through its own sewage outlet.
    When used in the production of emulsified modified asphalt equipment, depending on the modified material technology, the latex pipeline can be connected in front of the colloid mill or behind the colloid mill, or there may be no latex pipeline and it must be made manually. Add the required amount of latex into the soap jar.

    In modern highway maintenance work, how to repair asphalt pavement quickly and effectively has become one of the key issues. As an advanced repair technology, cold patching technology is very popular because of its convenient construction and remarkable effects.
    What is the cold patching process?
    Cold patching process, as the name suggests, refers to a technical method for repairing asphalt pavement without heating. This process uses a specially proportioned cold-patch asphalt mixture. This material can maintain good fluidity and adhesion even at lower temperatures, thus ensuring the quality of the repair.
    Advantages of cold patching process
    Fast construction: Cold patching materials can be directly applied to damaged areas without preheating, and are immediately open to traffic, greatly shortening repair time.
    All-weather construction: Whether in hot summer or cold winter, cold patching materials can be effectively constructed and are not affected by the weather.
    Easy to operate: Thanks to its good working properties, even small damaged areas can be repaired easily.
    Environmentally friendly: The construction process reduces environmental pollution and is in line with the concept of green construction.
    Application scenarios
    The cold patching process is suitable for various types of pavement repair work, especially those places where traffic needs to be restored quickly, such as urban main roads, highway ramps, etc. In addition, the cold patching process is also an ideal choice for remote areas or situations where professional heating equipment is lacking.
    In short, the cold patching process has occupied a place in the field of rapid repair of asphalt pavement with its unique advantages and has become an indispensable part of modern highway maintenance.
