TRC2204 - Materials and Testing for Drilled Shaft Concrete

Drilled Shafts are a common bridge foundation system used in Arkansas. Previous research has established best practices for mixture designs, mixing, placing, and testing drilled shaft concrete, but this work has not been implemented in Arkansas. Self-consolidating concrete can be used in drilled shafts to solve issues of aggregate segregation and consolidation. The purpose of this project is to determine a mix design for SCC that can be utilized across the state. Along with a new mix design, testing procedures are needed for SCC in the field, as well as specification for required QA/QC testing of drilled shaft concrete.
