Guide Specification for Service Life Design of Highway Bridges
The
majority of instances of explicit consideration of service life design has been limited to signature bridges
and other projects where extended service lives (in other words, greater than 100 years) are specified by the owner.
Many state departments of transportation and other transportation agencies have recognized the
importance of implementing service life design for typical highway bridges; however, no specification or
standard has been developed to date in the U.S.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 269: Guide Specification for Service Life Design of Highway Bridges provides a new guide specification on the service life design of
highway bridges for adoption by AASHTO, including a set of case studies that demonstrate its application.
