Service Life Design
Many state DOTs and other transportation agencies have recognized the importance of implementing service life design for typical highway bridges; however, no specification or standard had previously been developed in the U.S. This ultimately led to the initiation of NCHRP Project 12-108, which was led by Modjeski and Masters.
Modjeski and Masters developed the Guide Specification for Service Life Design of Highway Bridges to provide practical guidance to designers and owners on design decisions that affect the durability of highway bridges. Our work included the development of the guide specifications and accompanying case studies demonstrating its application. The document was constructed so that it can be used immediately by designers, while still allowing for future improvements as the findings of new research become available. Now adopted by AASHTO, this new specification will enable practical application of service life design provisions resulting in improved service life expectancy of bridges across the United States.
