Slotted irrigation joints are mainly used to deal with the cracks in the road and large cracks in large and medium repair, for the prevention of pavement disease prevention. Through the slotting machine on the cracks after slotting, with a hot spray gun or hair dryer tank slag and dust blowing, and then filling the sealant filling the sealant to the cracks, thus repairing cracks and to ensure the overall performance of the road,Anti rain series asphalt sealant Can extend the service life of the road. Slotting repair method is suitable for small and medium-sized cracks, but also domestic and foreign common crack treatment methods, the use of major equipment, including slot machines and filling machine, with a hot spray gun or hair dryer assistance. The material used for the repair is made of a sealant material (modified asphalt polymer) specifically designed for crack repair. Generally slotted to note that the slot size of at least 1 cm wide, 1 ~ 3 cm deep, slot depth, width ratio should not exceed 2: 1, the depth ratio is better.
With the slotted irrigation joints treatment of road cracks repair method Construction process: First, the preparatory work: check the slotting machine and filling machine, to ensure that its technical condition is good; according to the specific situation of road cracks to determine the sewing design; And then add the sealant to the sealant heating tank,Concrete Trowel buying online the sealant heating, stirring to 193 ℃, can not exceed 204 ℃; heating during the filling machine will be trailer in the back of the truck, and sealant, isolation pier, safety signs , Slot machines and shoulder-back hair dryer or hot spray gun mounted on the truck, dragged to the scheduled construction site, half of the road half of the closed as a construction area.
Slot: According to the design of the slot size, pre-adjust the slotting slot depth, and then slot operation. Operation, according to the type of crack width, timely adjustment slot size, to meet the minimum requirements of irrigation joints. Clear the tank: with a hair dryer or hot spray gun will be inside the slag and cracks on both sides of the dust at least 10cm within the clean sweep, clean, dry, suitable for the temperature of the irrigation joints. Filling: (Note: If the temperature is lower than 5 ℃ when the sewing, filling machine must be equipped with a hot spray gun on the out of the slot heating, if the temperature does not heat the tank, will reduce the road crack sealant Cohesive force; if the temperature is higher than 5 ℃ when the patch, can not be heated, the general effect of heating after the patch is better.) In the sealant to the construction temperature, with a filling gun to seal the glue evenly into the tank,Stable quality rural road maintenance facilities And the filling machine gun with a scraper head, you can scrap the material away, so that the two sides of the cracks in the same width and thickness of the seal band. Open traffic: with road crack sealant irrigation, the road crack sealant is fully cooled and the slag on the road clean, in order to open the traffic, the general cooling time of 15 minutes or so, the specific open traffic time according to the temperature Flexible mastery.
