Small asphalt caulking machine belongs to pavement machinery, which is mainly used for preventive maintenance of pavement diseases. It is generally used together with slotting machine, caulking machine, blower (or thermal spray gun). Caulking machine is the core equipment of caulking technology. Cracks are one of the main forms of early diseases of expressway, among which linear cracks such as transverse cracks and longitudinal cracks are common.

The caulking machine adopts hydraulic drive mode to provide power for asphalt mixer drive motor, asphalt pump drive motor and thermal oil circulation drive motor. Generally speaking, joint filling is a link of the whole pavement joint filling operation. Before joint filling, it is necessary to see whether it is necessary to expand the joint according to the situation of the joint, and then spread stone chips as appropriate after joint filling.

For some small joints, before grouting, the small joints should be expanded into construction joints with a depth of 40mm and a width of 12mm with a joint expander, and then repaired with a joint grouting machine after cleaning. After grouting, the preheated stone chips are evenly distributed on the seam dragged by the iron, so as to complete the repair of a crack.
