ADOT performs pavement design using the following methods:

1. The 1993 AASHTO Guide for Design of Pavement Structures*
2. The Structural Overlay Design for Arizona (SODA) procedure*

*Upon approval, ADOT uses "AASHTO’s Mechanistic – Empirical Pavement Design Guide" in parallel with the design methods mentioned above.
