Crack router：Rotary impact excavator, can automatically track the crack, easy to operate.
Crack sealing machine：It has a double insulation layer and thermal mixer, which can control the temperature on full screen to ensure that the instrument can accurately reflect the specific temperature of the pavement sealant to facilitate staff to carry out investigation on the situation of the road, also ensure constant temperature of delivery tube. Crack sealing machine can also maintain temperature of the sealant in the lance tip , the material pump system can pump the sealant material into the box, which can protect the hose performance, also improve the heating efficiency of the heating compartment.
During the selection of the sealant , pay attention to those who join a variety of asphalt rubber polymer component, this sealant has strong adhesion, flexibility, scalability and other advantages, it does not dissolve in water, even at very high temperature will not melt and flow, which ensure the maintenance to be stability and robustness of the road. However, our current research the asphalt pavement potting material is not perfect, the selection of sealant can reference to foreign technical specifications selection and use.
