When adding materials, be sure to open the emulsified oil valve of the emulsified asphalt equipment first, and then open the asphalt valve to prevent the motor stator from seizing. The inner diameter gauge of the emulsified asphalt equipment is generally adjusted to the 0 position at the original factory. Adjust the gap to the right. The change of one small grid on the inner diameter gauge is 0.01mm. It can be adjusted to the ideal gap anytime and anywhere as needed.

    The function of slurry seal is to use appropriately graded stone chips or sand, fillers (cement, lime, fly ash, stone powder, etc.) and emulsified asphalt, admixtures and water, and mix them in a certain proportion to form a flowing asphalt mixture, which is evenly spread on the road surface to form an asphalt seal. This seal is mainly used for roads in rainy areas, especially when the gaps in the asphalt surface layer are large and easy to seep water, the slurry seal can effectively solve this problem.
    In addition, after the base layer is laid, if the asphalt surface layer cannot be laid in time and traffic needs to be opened, the slurry seal also plays a key role. It can temporarily close the road surface to prevent rainwater from penetrating, while protecting the base layer from damage. The slurry seal has strong fluidity and can better adapt to various road conditions to ensure construction quality and efficiency.
    Compared with the viscous seal, the slurry seal has higher adaptability and flexibility. Due to its poor fluidity, the viscous seal is more difficult to spread evenly during construction, and it is more likely to flow in a humid environment, affecting the construction effect. The slurry seal, due to its strong fluidity, can better cover the entire road surface and ensure the uniformity and integrity of the seal.
    In practical applications, the slurry seal also has the advantages of fast construction speed and low cost. Due to its good fluidity, less equipment and manpower are required during construction, which greatly shortens the construction period. In addition, the material cost of the slurry seal is relatively low, which effectively controls the overall construction cost.
    Therefore, when choosing the seal material, the slurry seal has become a more ideal choice due to its excellent performance and economy. Whether it is for road maintenance in rainy areas or for base protection, the slurry seal can play an important role in ensuring the safety and service life of the road.

    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.
