Will AASHTO’s National Transportation Product Evaluation Program (NTPEP) datamine test data be acceptable for my application?

NTPEP test data are acceptable if the ADOT specification for your product category requires NTPEP testing. Please review the specifications to determine whether this applies to your product. When applying, please specify where that data is stored in the NTPEP datamine. For product categories with requirements not covered by the NTPEP testing, please provide independent test data from an accredited lab.

ADOT’s Tentative Five-Year Construction Program touts safety, innovation and collaboration

Safety, innovation and collaboration are the three main priorities I have as the director for the Arizona Department of Transportation. Our 2024-2028 Tentative Five-Year Construction Program addresses these priorities as we work to improve and maintain the state’s highway system during the next five years.

May I submit a Certificate of Compliance (COC) or Certificate of Analysis (COA) instead of test data for my product?

COCs and COAs do not substitute for the required test data. In addition, having a product on the APL does not exempt a vendor from submitting a COC or COA prior to the product's use in construction.
