The asphalt binder reference cost is established by WSDOT from the selling price of asphalt cement furnished by Poten and Partners, Inc. for the Pacific Northwest:

  • Western reference cost is based on the selling price for the Seattle, Washington area
  • Eastern reference cost is based on the selling price for the eastern Washington area including northern Idaho

The asphalt binder reference cost will be the average of the selling price for each Friday during the specified period.
