Crack Seal

Crack Seal is one of the most economical pavement maintenance tools for asphalt and concrete pavements. Crack Seal is a process in which a bituminous product is applied to open cracks and joints in a roadway surface. This process is the key to keeping water out of the pavement subbase which in turn will help provide long pavement service life.

Crack Seal should be used as soon as possible when normal cracking above 1/4 inch first appears in a paved surface.

Process

Cracks are cleaned with a stream of high pressure air. Using a double jacketed, pressurized crack sealing machine, one or two workers follow with wand like applicators directing the sealant into the opening of the crack leaving an overband on either side of the crack. This overband should be no more than 2.5 inches and very thin on top. Care must be taken not to over fill leaving a slippery surface in driving lanes, curves or approaches to intersections. Traffic may resume in 10 to 15 minutes depending on weather conditions.

Value Added Benefits

  • Less costly than most preventative maintenance tools
  • Prevents water intrusion
  • Ideal preparation for future bituminous treatments
