Why chip seal?
  • To keep water from penetrating the road structure on paved surfaces.
  • To fill and seal cracks and raveled surfaces of old pavement.
  • To provide an anti-glare surface during wet weather and an increased reflective surface for night driving.
  • To rejuvenate the pavement surface-minimizing the effects of aging.
  • To provide a highly skid-resistant surface, particularly on wet pavements.
  • The process moves along very quickly and traffic can drive on the newly chipped road almost immediately minimizing lengthy delays.
  • The cost of chip seals is 15%-20% of the cost of pavement overlays.
  • Chip seal is expected to provide 5-10 years of wear life depending on traffic volumes before additional work is needed.
What is the process for chip sealing?
  • Streets are evaluated for their maintenance needs.
  • Crews come in and patch any of the failing areas of roadway.
  • Another crew then cleans and fills any large cracks with crack seal- a special hot applied rubberized filler.
  • Now the chip seal process begins. An emulsified mixture is applied to the road using a special spray truck
  • Immediately after spraying this liquid asphalt, a layer of crushed gravel is applied by a spreader.
  • Next, the gravel is compacted and embedded into the asphalt by rubber-tired and steel drum rollers.
  • The new chip-seal surface can require up to two days to cure properly. After it has fully cured, the loose gravel is swept off the surface and a fog seal is applied to the road surface to seal the surface and give it that finished look.
  • Once fog sealed, the paint striping, legends, and crosswalks can be replaced completing the process.
