Fractures are one of the main forms of early diseases in highways, among which linear cracks such as transverse and longitudinal cracks are the most common. The seam filling technology is a treatment technology for these diseases, covering the seam filling materials, seam filling equipment and seam filling technology. The seam filling machine is the core equipment of seam filling technology. The function of the seam filling machine is to heat the cracks after the cracks are troughed and cleaned, and evenly pour the sealant into the groove with a seam filling gun to complete the seam filling work.

Small seam filling machine is suitable for simple road maintenance. The small seam filling machine adopts a liquefied gas heating system, which circulates thermal oil to quickly melt asphalt or seam filling glue, and achieves the effect of crack treatment through the pressure of the asphalt pump. Through pressure injection, the material and the seam wall are closely combined, and the flexible universal wheel is turned to track the cracks, making the seam filling effect beautiful. Since the seam filling material uses asphalt or seam glue, it is easy to solidify when the temperature is low. The seam filling machine is equipped with a Yamaha generator set to provide the power of the whole machine. The seam filling machine adopts a constant temperature control system at the discharge pipe to avoid burning and aging of the material. , ensure smooth delivery
