The crack sealing equipment is mainly used for preventive maintenance of road diseases and is generally used in conjunction with a slotting machine, a joint filling machine, a hair dryer (or a thermal spray gun). The function of the crack sealing machine is to heat the cracks after grooving and cleaning the cracks and use a filling gun to evenly pour the sealant into the grooves to complete the joint repair work. YG asphalt crack sealing equipment can be divided into asphalt crack sealer machine, hand-push crack filling machine. Click the message box below to get the Crack Sealing machine price.
Working Principle of the Crack Sealing Machine:
The asphalt sealing equipment adopts an automatic heating control system. It can not only greatly reduce the emission of pollutants, but also effectively improve the efficiency of the filling. In addition, the pavement asphalt filling machine also adopts an intelligent control system, which makes operation flexible, accurate flow output, and ensures smooth and beautiful pouring. YG asphalt crack filling machine plays an important role in road maintenance. Click the message box below to get the price of asphalt sealing equipment.

Construction Requirements of Asphalt Crack Sealing Equipment:
- Construction temperature: The construction temperature is one of the reasons that cause the sealant to fall off. Wet pavement and temperature below 4°C will reduce the adhesive force of the sealant and easily fall off. The overall temperature of the road surface is low. After the sealant is filled, the temperature drops quickly, the sealant shrinks significantly, and the temperature stress between the sealant and the groove wall is relatively large, which will reduce the bonding force between the sealant and the road surface.
- Crack humidity: The pavement should be dry when filling the joints. If wet, it will reduce the adhesion of the sealant and the pavement, causing part of the sealant to fall off.
- Keep clean: Before filling the joints, use an air compressor to remove the dust and sundries in the cracks after the groove and the loose objects around them, and keep the cracks clean.
- Range of filling joints: the rutting is serious, especially the pavement that forms network cracks, this method is not suitable for treating cracks.

How to Prolong Road Life?
Pavements are often defective and damaged due to the effects of rolling, impact, wear, and weather changes on the road. The damaged road surface has a detrimental effect on the vehicle’s driving speed, load capacity, fuel consumption, mechanical wear, driving comfort, as well as traffic safety, and environmental protection.
Road damage is divided into many types, road cracks are just one type. In order to prolong the life of the road and keep it in good condition, it is necessary to take appropriate engineering and technical measures according to different requirements. On the one hand, it is necessary to repair damaged parts in time, and always keep the road intact, smooth, clean, and beautiful. On the other hand, periodic preventive repairs are carried out, which can improve the quality of the road.
