Nondestructive Evaluation of Pre- and Post-Tensioned Tendons: Void Detection and Corrosion Monitoring

Recent inspection of a precast segmental post-tensioned bridge in Florida indicated that voids are a leading cause of corrosion. A novel nondestructive evaluation technique using time domain reflectometry (TDR) to detect, locate, and identify voids and the extent of defects has been developed and demonstrated. Experimental results from both small-scale laboratory tests and field implementation are reported.
