Approved Products List

The Approved Products List (APL) is updated every month. Changes to the APL are approved by the ADOT Product Evaluation Committees and are implemented by the first week following their action.

Please review Federal Highway Administration memorandums and documents for product Category I, II, III and IV certification requirements and approvals. A copy of the NCHRP Report 350 is available for review.
