This specimen is believed to be from TxDOT Research Project 5-6652-01, which investigated the shear behavior of spliced post-tensioned girders with ungrouted tendons. Spliced girders are built from multiple precast segments joined with post-tensioning after placement.

The project had a related predecessor (0-6652) that studied similar behavior in girders with grouted tendons. Both projects contributed to updated TxDOT design guidelines for long-span bridge applications where rapid construction and high shear performance are required.
