Continuous Long-Term Health Monitoring using Ultrasonic Wave Propagation

This report presents the findings of a research project on using ultrasonic testing to continuously monitor reinforced concrete bridge decks for the onset of delamination. The report first presents a review of current nondestructive testing techniques used in practice and research, and deficiencies of these methods. Then the novel method developed in this project to identify early delamination in reinforced concrete bridge decks is presented. This method uses a unique sensor setup compared to current ultrasonic testing methods and utilizes the waves leaked into the concrete from the rebar that is excited with ultrasonic waves.
