【Background technique】

After the asphalt road has been used for a period of time, the asphalt mixture will be aged and deteriorated, the road surface is prone to cracks, and the rainwater will continuously invade into the cracks, resulting in the subsidence of the road foundation, and the bearing capacity of the asphalt mixture road will become lower and lower. This makes the asphalt mixture pavement appear broken, collapse and other diseases, which seriously affects the traffic safety. One of the most important aspects of the maintenance of asphalt pavement is the early maintenance of asphalt pavement cracks and timely filling, which is of great significance to prolong the service life of asphalt pavement and improve the bearing capacity.

The traditional way of maintaining asphalt roads is to use a slotting machine to open the cracks into regular grooves with a depth of 0-50mm and a width of 8-50mm, and then pour the asphalt mixture into the joint filling machine, and pour the asphalt mixture into the joint filling machine. The tank needs to be cleaned before feeding. Traditionally, a blower is used to blow the old asphalt material in the tank clean. This treatment method has serious environmental pollution, and the old asphalt material cannot be blown cleanly, requiring further manual processing, and the work efficiency is low.
