Materials Evaluation Program
Submit payment for Aggregate Source Approval (ASA) and Qualified Products List (QPL) evaluations.
For QPL applications, the MEP will prompt the user to pay a preliminary Phase 1 Evaluation fee. QPL submittals for HMA Mix Designs are exempt from the Phase 1 Evaluation fee. This fee will cover the cost of the initial application review, consultation with Subject Matter Experts, and if WSDOT chooses to proceed, the cost of developing an official letter and cost sheet for the full evaluation.
The requesting party will then be able to submit electronic payment for the full evaluation fee. Upon receipt of payment, the MEP will notify the QPL or ASA Engineer to proceed with the full QPL or ASA evaluation.
