AASHTO made specific changes to the following specification sections within that publication: Section 3 General Requirements; Section 4 Analysis and Design Requirements; Section 5 Analytical Models and Procedures; and Section 6 Foundation and Abutment Design.

AASHTO said it is necessary to have those 2022 updates – as well as the interim revisions issued in 2012, 2014, and 2015 – in order to have all current specification information on hand.
