Crack sealing technology is used to avoid the rainwater infiltration and delay the pavement damage in the asphalt pavement with crack, through filling the sealing materials into the crack.

1.Technological procedures:

2.Construction Process:

3.1 Using the slotting machine KD-25 to cut the irregular crack into regular groove with width less than 1cm,depth 1-3cm. The rate of the depth and width should be less than 2:1 as small as possible.

3.2 Using the blower to clear the pavement

3.3 Using RD-940 for drying

3.4 Using GD5X-350 for sealing

3.5 Crack sealing effect
