Abstract:As part of a national experiment sponsored by the FHWA under the Innovative Bridge Research and Construction (IBRC)
program, CDOT used self-consolidating concrete (SCC) to construct abutments, piers, and retaining walls on a bridge
replacement project. The purpose of this study was to determine the procedures and possible benefits associated with
flowing concrete. Based on the study presented in this report, it was determined that SCC was used successfully in the I-25
bridge replacement project in Trinidad. Unfortunately, the all-around lack of construction experience with SCC resulted in
numerous aesthetic problems that are atypical of the material. However, despite numerous visual defects that required
patching and repair, it is believed that each component has the required structural integrity necessary for safe highway
transportation projects.
