Asphalt binder reference cost

Find the latest average selling price of asphalt cement for both eastern and western Washington.

An asphalt cost price adjustment provision is included in all of our contracts that use hot mix asphalt. The prices published below are used to determine the credit or payment amount when there are qualifying changes in the reference cost of asphalt binder, as specified in the contract special provisions. This information is updated frequently, however, there is no set schedule. The reference cost posted is for the period immediately preceding the bid opening date.

We establish the asphalt binder reference cost 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. Asphalt binder reference costs are posted at the end of the period.
