TRB’s SHRP 2 Tuesdays Webinar: Mapping Defects In or Behind Tunnel Linings (R06G)

As part of the SHRP2 Tuesdays Webinar Series, TRB conducted a webinar on April 22, 2014 from 2:00 pm to 3:30 pm ET that explored the SHRP 2 project High-Speed Nondestructive Testing Methods for Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings.

View recorded webinar.

The webinar summarized SHRP 2 Project R06G, which identified nondestructive testing (NDT) technologies for evaluating the condition of various types of tunnel linings and tunnel lining finishes. The project then evaluated the applicability, accuracy, precision, repeatability, ease of use, capacity to minimize disruption to vehicular traffic, and implementation and production costs of the identified technologies. The project also advanced hardware and software development for the most promising technologies and proved the validity of the selected technologies to detect flaws within or verify conditions of the targeted tunnel components.

Webinar Presenters

• Andrew Wimsatt, Texas A&M University
• Matthew DeMarco, Federal Highway Administration (FHWA)

Moderated by: Andrew Horosko, Transportation Research Board

Webinar Outline

• PART 1: Brief overview of SHRP 2 mission, objectives of the Renewal focus area, and related SHRP 2 research
• PART 2: The results and experience gained from identification and testing of the nondestructive testing technologies
• PART 3: Plans for implementation
• PART 4: Question and answer session

The first 60 minutes of the webinar were for presentations and the final 30 minutes were reserved for audience questions.

Learning Objectives
At the end of this webinar, participants were able to:

• Select nondestructive testing technologies that improve inspection and detection and reduce traffic disruption, and
• Describe test procedures and protocols to successfully implement those technologies.
