Crack Sealing is a process where using specialized equipment, aggregate is simultaneously premixed with a heated asphalt emulsion and sealing through a hose and nozzle into the pothole. Specifically, the steps take to fill the pothole when using pothole repairing equipment include:
Blowing water and debris from the pothole
Applying a tack coat of asphalt emulsion on the sides and bottom of the pothole
Spraying the emulsion and aggregate mixture into the pothole
Covering the repaired area with a thin layer of uncoated aggregate
Opening the repair to traffic as soon as workers and equipment are clear.
The Crack Sealing process requires no compacting after the cover aggregate is placed.
The Crack Sealing Machine offers potential for much greater productivity and efficiency and can operate in extreme cold weather. Effective road repair operations are possible in the winter month when adverse weather prevents traditional pothole repairs from lasting through the season.
