Highway Research Center (Auburn University)
Self-consolidating concrete; prestressed concrete; bridges
This research project consists of implementing the research previously conducted by Auburn University for ALDOT on self-consolidating concrete's application in the precast & prestressed concrete industry on an actual ALDOT project. In the demonstration project, a bridge would be constructed using girders made from SCC and conventional concrete for side-by-side comparison. Phase I of the project consisted of developing a draft special provision for the use of SCC, selecting a test bridge, evaluating new fresh property test methods from previous research, monitoring the fabrication of the girders, and monitoring the pre-erection structural performance of the girders. Phase II of the project consisted of monitoring the construction of the demonstration bridge, load testing of the bridge, monitoring in-place structural performance of the bridge, and making recommendations for the final revisions to ALDOT's SCC spec.
