Abstract
The Kentucky Transportation Cabinet (KYTC) has both open and closed bridge expansion joints and associated details that are problematic. Several state highway agencies (SHA) have joints that they believe are superior performers to other types and have prepared guidance documents for their use. A literature search indicated that several previous research studies, including national surveys, addressing SHA joint practices have been conducted over the past 10 years. For up-to-date information, a new set of surveys were developed and distributed to all the SHAs by email through the AASHTO Subcommittee on Maintenance-Bridge Technical Working Group chairman in June 2010. There were two sets of surveys: 1)design and construction; and 2) maintenance that were submitted to two separate entities within each SHA.
