2015 INTERIM REVISIONS TO THE AASHTO INSTRUCTIONS AND INFORMATION LRFD BRIDGE DESIGN SPECIFICATIONS

iii

INSTRUCTIONS AND INFORMATION

General AASHTO has made interim revisions to the AASHTO LRFD Bridge Design Specifications, Seventh Edition (2014).

This packet contains the revised pages. They are not designed to replace the corresponding pages in the book but rather to be kept with the book for quick reference.

Affected Articles

Underlined text indicates revisions that were approved in 2014 by the AASHTO Highways Subcommittee on Bridges and Structures. Strikethrough text indicates any deletions that were likewise approved by the Subcommittee. A list of affected articles is included below.

All interim pages are printed on pink paper to make the changes stand out when inserted in the third edition binder. They also have a page header displaying the section number affected and the interim publication year. Please note that these pages may also contain nontechnical (e.g. editorial) changes made by AASHTO publications staff; any changes of this type will not be marked in any way so as not to distract the reader from the technical changes.

Please note that in response to user concerns, page breaks are now being added within sections between noncontiguous articles. This makes it an option to insert the changes closer to the affected articles.
