Abstract:The Louisiana Department of Transportation and Development (LADOTD) has been gradually
introducing high performance concrete (HPC) into their bridge construction programs. The
Rigolets Pass Bridge is a 62-span bridge with a total length of 5,489 ft. (1,673 m). HPC was used
in two of the 62 bridge spans. These spans each utilized four 131.2-ft. (40-m) long BT-78 girders
at 12-ft. 7-in. (3.83-m) spacing. In conjunction with the Rigolets Pass Bridge Project, the state
initiated a research program with the objective of monitoring the structural behavior of one of
the two HPC bridge spans. The research program was jointly performed by the Tulane University
Department of Civil and Environmental Engineering, CTLGroup, and Henry G. Russell, Inc.
under the sponsorship of the Louisiana Transportation Research Center (LTRC) in cooperation
with LADOTD.
