Crack sealing (rout and seal) and crack filling (no routing) are crack treatment activities that have been used to treat pavement having low to moderate crack density. A pavement that has a large number of cracks or severely deteriorated cracks generally indicates a pavement in an advanced state of disrepair. Under such circumstances, crack sealing or filling is ineffective. It should be noted that crack sealing is a longer term treatment while crack filling is considered more of a short term treatment.
Provide unit applicators, used for heating and installing the hot-poured crack sealant materials, that are mobile and equipped with a double-boiler, agitator-type kettle with an oil medium in the outer space for heat transfer; a direct-connected pressure-type extruding device with a nozzle shaped for inserting in the crack to be filled; positive temperature devices for controlling the temperature of the transfer oil and sealant; and a recording type thermometer for indicating the temperature of the sealant.
Crack sealing machine can be operated by two people with safety. Allow the sealant to circulate through the delivery hose and return to the inner kettle when not in use, due to the applicator unit design. If you have any question about the crack sealing machine, welcome to contact us.
