Abstract:

Advancements and increased use of accelerated bridge construction (ABC)

often result in the use of newly developed, or modified, technologies and/or

construction techniques that are sometimes untested in this new application.

For designers and engineers to confidently make use of these technologies and

construction methodologies, evaluation of their performance relative to design

assumptions, short- and long-term durability, and other performance-based

metrics is required in laboratory tests.

One particular technology that has been transferred and utilized in several ABC

projects are grouted reinforcing steel couplers. One specific project in particular,

the Keg Creek Bridge on US 6 in Iowa, utilized grouted reinforcing steel couplers

to connect drilled shafts to prefabricated pier columns and then the pier columns

to prefabricated pier caps.
