CHIP SEAL

Chip Seal Fact Sheet

 

“Chip Sealing” is a common pavement maintenance practice that extends pavement life and provides a good driving surface.  Since some you may not be familiar with the chip seal construction method, this fact sheet answers some frequently asked questions.

 

How are Chip Seals Different from Asphalt Overlays?

 

The difference is in the construction method.  Hot Mix Asphalt pavement is produced by heating liquid asphalt and mixing it with aggregate, with the mix then spread and compacted to form a durable road structure and riding surface.  Chip Sealing uses the same ingredients as asphalt concrete paving, but the construction method is different.  With chip seals, a thin film of heated asphalt liquid is sprayed on the road surface, followed by the placement of small aggregates ("chips").  The chips are then compacted to orient the chips for maximum adherence to the asphalt, and excess stone is swept from the surface.  The ingredients of hot mix asphalt and chip seals are the same; only the construction methods are different.

 

Why Use Chip Seals?

 

  1. Chip seals provide you the opportunity to maintain the roads for very low cost.

  2. By extending the time between asphalt overlays, chip seals result in lower costs over the long term.

  3. By placing a chip seal sooner than an asphalt overlay would be placed, the traveling public benefits from roads maintained in better condition.

  4. Chip Seals eliminate the need to crack seal.

  5. Chip seals enhance safety by providing good skid resistance.

  6. Chip seals provide an effective moisture barrier for the underlying pavement against water intrusion by sealing cracks in the pavement.

  7. Chip seals prevent deterioration of the asphalt surface from the effects of aging and oxidation due to water and sun.

  8. TDOT has successfully used chip seals for over 25 years to maintain state routes.

  9. Chip seals are used only on low traffic routes, less than 2500 vehicles per day.

  10. Chip seals virtually eliminate black ice.
