Research Center

The Research Center is a catalyst for innovation at the Arizona Department of Transportation. The Research Center engages in three major functions: administering the department's research program, managing the product approval program and maintaining a transportation library.


Projects administered by the Research Center focus on research that can be applied to improve ADOT processes and products. Research projects address the full range of topics of interest to the department.

Product Evaluation Program

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