Supported in part by the Oklahoma Department of Transportation, Floyd and Yadak worked closely with the contractor and the U.S. Army Corps of Engineers on the three-year project.
The Eufala dam is the first bridge in the state to use ultra-high performance concrete for connections of precast deck panels and for an overlay. UHPC is an innovative cementitious material with material properties and durability significantly exceeding that of conventional concrete. Floyd provided advice about the new material and the best methods to use during planning, pre-construction and application. He and Yadak measured compressive strength, removed cores from the bridge mockup and tested the UHPC.
