Sealcoating – Oil and Chip

Asphalt roadways with significant cracking have been a maintenance challenge.  Reflective cracking occurs quickly with ordinary surface treatments, making maintenance an ongoing need.  Removal and replacement of the roadway can be a successful but a costly alternative.

The process begins with cleaning the roadway surface, utilizing high- speed air blowers and/or mechanical sweepers.  So the pavement cracks of ¼ inch wide or wider can be filled with a hot-applied rubberized crack sealer.  Then hot oil and polymers are applied to the surface.  Immediately following the oil application, aggregate is evenly placed using a chip spreader.  Afterwords a pneumatic roller is used to compact the aggregate in place.  After curing, loose stones are swept from the pavement surface.  The final step is the application of  asphalt emulsion known as “fog seal”.  The fog seal provides an attractive appearance while improving surface cohesion.

The chip seal system remains flexible at cold temperatures and maintains integrity at high temperatures to help reduce reflective cracking.  The finished surface requires very little maintenance and is extremely durable.
