Development of the Crack sealing machine

Crack sealing machine belongs to road machinery, mainly used for preventive maintenance of road diseases. It is generally used in conjunction with slotting machine, grouting machine, hair dryer (or hot spray gun). Grouting machine is the core equipment of grouting technology.

The function of the Crack sealing machine is to heat the crack after the slotting and cleaning steps, and use a grouting gun to evenly pour the sealant into the groove to complete the patching work. We all know that cracks are one of the main forms of early diseases on highways, with the most common being transverse cracks, longitudinal cracks, etc. Our crack filling technology mainly focuses on the treatment of these diseases, covering crack filling materials, equipment, and processes. Grouting machine is the core equipment of grouting technology.

Crack sealing machine is a relatively mature technology abroad, and the development of grouting machines is also relatively mature. The most influential grouting machine manufacturers include American companies, Canadian companies, German companies, Canadian companies, American companies, German companies, etc. The most influential among them is the American company, which is the only influential company in the world that produces both road maintenance equipment and various road maintenance materials. Its products are also used in China. The products of these companies have basically been serialized, and their product drivers, heating, flow control, etc. are different from each other.

With the rapid development of Chinese highways, especially high-grade highways, the requirements for maintenance technology and equipment are also increasing. In addition to the maintenance department importing some highway crack treatment machinery and materials from abroad, some domestic enterprises have also begun their own product development work.

The majority of road crack treatment operations carried out by domestic maintenance departments are manual and semi mechanized. The introduction and independent development of these equipment undoubtedly promote the reform of China's road maintenance system and the mechanization of road maintenance.
