AASHTO has released the fourth edition of its "LRFD Bridge Construction Specifications," which supersedes the 2010 third edition and interim revisions, along with a video (below) highlighting the new publication.
These specifications, which state departments of transportation and other industry participants use to build roadway bridges, employ the load and resistance factor design methodology and are designed to be used in conjunction with AASHTO's separate publication on "LRFD Bridge Design Specifications."
This new edition includes a complete revision of the third edition's section on temporary works, plus significant updates to sections on pre-stressing, steel structures, bridge deck joint seals and concrete culverts.
The AASHTO Highways Subcommittee on Bridges and Structures oversaw its development.
The 566-page publication is
available to purchase through the AASHTO Bookstore in a looseleaf print version or as a downloadable PDF, at both AASHTO member and non-member prices. Customers can also purchase a set that includes both the print and PDF versions, and which includes additional savings.
