(1) slotted. First start the slotting machine, the engine speed to adjust to the maximum, and then lift the T-clutch handle, move the knife head lift switch will crack tracking indicator alignment cracks, pull back slot machine, can automatically along the crack path Slotting operation. For the slit line can be marked for the mark.

(2) clearance. The use of hot air gun to produce high-pressure air on the grooved cracks to clean up,Use High Quality Vibratory Roller especially the water wet cracks, the use of hot air gun can remove dust and debris, but also on the crack drying and a certain degree of heating, Strengthen the bonding materials and cracks in the bonding operation.

(3) irrigation joints. Start filling machine, to the hopper by adding high-elastic sealant, and then set the control box on the filling material temperature, open the control box on the burner switch,classic seal coats working principle heating 45 minutes, the material can reach the set temperature, then the Remove the heating hose, trigger the trigger on the gun, you can to the cracks in the filling material, the material can be adjusted according to the actual speed of the situation. And finally with the sealant in the slot about 30mm stick around.

(4) cooling. After filling, let the sealant cool for 20 minutes to release.

Application results.

After the cracks were treated for half a year, the road sections were tested and the results were as follows.

(1) the seepage test on the irrigation joints and found good water sealing effect, the road surface water is difficult to infiltrate the basement.

(2) from the core pulling and excavation situation,cement driveway crack repair the slurry only into the cracks in the gap, and did not enter the intact asphalt layer, indicating that the expected results.

(3) From the deflection test, the deflection value after grouting is obviously smaller than that before grouting, and the deflection value is close to that of the intact section, which shows that the grouting fill-up joint has played a reinforcing role, and the top- Modulus has also been improved.
