Abstract:
Bridge substructure repairs that were completed using self-consolidating concrete (SCC) are described. The Virginia Department of Transportation (VDOT) has successfully used SCC on bridge repair projects for about 5 years. Placement and testing requirements for SCC are similar to those for conventional concrete, the required formwork provides initial protection against moisture loss, and the finish can be as smooth as the formwork surface. Completed repairs show that SCC can be successfully placed, and the finished product has minimal cracking.
