1. Slotted
Using a dedicated road cutting machines to perform that operation,cracks in accordance with label,according to the width and depth of cracks,adjust road cutting machine slot width and depth,midline aligned cracks cut uniform U-shaped groove,cracks at least two side walls of each removal of 3 mm,the new adhesive surface exposed.It is emphasized that,when the asphalt pavement surface layer does not have sufficient strength to withstand the impact of slotting cutting machine,not suitable for processing notching,but rather directly to the next step of the process,which is caulk.
2. Sealing
Pouring glue heated to a temperature sink,pressure nozzle with a crack sealing machine with Calibrating after the can seam glue evenly poured into the tank,to ensure the temperature does not fall pouring glue,the discharge pipe should be fitted with heating function.Pouring nozzle needle can be used,recommended small slippers dragged into the cracks on both sides of 5 cm width of the seal coat paste,rack each work should be continuous perfusion,such as cracks filled letters unfinished required to fill and seal again.
3. Open the traffic
10-20 minutes after the opening of the cooling air temperature according to traffic conditions,in order to prevent the wheels from pouring glue stick, sometimes sprinkled sand on it after pouring.
We are Shanghai Doan Machinery Technology Company, and our company is also additives imported imported cold patch cold pouring sealant joints with new road pavement paste stickers affixed to plastic joints cracking concrete grassroots quick fix glue waterproof anti-corrosion materials road bridge anti-rutting agent emulsified asphalt and other products,for you to choose.
