For the application of asphalt crack sealant, please refer to the following steps:

Preparation: Place the joint sealant into the heating equipment and heat it until melted, typically to 190-200°C. Ensure the joint sealant is evenly heated during the process and avoid localized overheating. Filling the Joint: Pour the melted joint sealant into the sealant machine, start the machine, and inject the sealant into the cracks. The sealant should fill up to the crack height, ensuring fullness. Curing: Once the joint sealant has cooled, it will achieve the curing effect. The cooling time generally varies with weather conditions and requires patience until the joint sealant is completely cooled. Reopening Traffic: After the joint sealant has fully cooled, traffic can be reopened. It is generally recommended to allow the joint sealant to dry before allowing vehicles to pass to avoid any impact on the sealant.

Additionally, the following points should be noted during use:

Before repairing asphalt pavement cracks, the cracks should be cleaned and dried to ensure the interior is clean and dry. When using asphalt crack sealant for repairs, select the appropriate construction method and materials based on the size and depth of the cracks. During the repair process, pay attention to safety to avoid accidents. After traffic is reopened, strengthen the observation and maintenance of the repaired area to ensure the quality of the repair and the safety of the road surface.
