The Research Center is dedicated to inquiry and innovation at the Arizona Department of Transportation. The Research Center manages the department's research program and product evaluation program.
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.
The Approved Product List (APL) is updated every month. Changes to the APL must be approved by the ADOT Product Evaluation Committees: Materials Product Evaluation Committee (MatPEC) and Traffic Control Product Evaluation Committee (TCPEC).
The ADOT Library is closed. Reports published by ADOT and other Arizona agencies, both print and digital versions, have been transferred to the State of Arizona Research Library -- State Documents, located at 1901 W. Madison Street, Phoenix. ADOT staff will be notified when the collection has been processed and made accessible. Limited digital archives remain temporarily available on the ADOT site.
