Construction Guide
Jiatong Road Caulking Glue Construction Method: Mainly through slotting and caulking to seal pavement cracks, the existing treatment method ~ caulking or caulking construction steps are: slotting, cleaning, caulking (needle type or sealing type)
Slotting: Use a special slotting machine for this operation. According to the crack marking, according to the width and depth of the crack, adjust the slotting width and depth of the slotting machine, and cut a uniform U-shaped groove in line with the center line of the crack. At least 3 mm is removed from both sides of the crack to expose the new bonding surface. It should be emphasized that when the surface layer of the asphalt pavement does not have sufficient strength to withstand the cutting impact of the slotting machine, it is not suitable to perform slotting, but should directly enter the next process, that is, caulking. Use Giti caulking glue to caulking: Heat the road caulking glue to the caulking temperature, use the pressure nozzle with a scraper on the caulking machine to evenly caulk the can caulking glue into the groove. To ensure that the temperature of the road caulking glue does not drop, the discharge pipe should be equipped with a heating function. Needle nozzles can be used for caulking. The caulking work of each crack should be continuous. If there are cracks that have not been completely sealed, they need to be sealed again.
Open traffic: Open traffic after cooling for 10-20 minutes according to the temperature conditions. In order to prevent the wheels from sticking to the caulking glue, sometimes some fine sand should be sprinkled on it after pouring the road caulking glue.
