As part of the SHRP2 Tuesdays Webinar Series, TRB will conduct a webinar on April 22, 2014 from 2:00 pm to 3:30 pm ET that will explore the SHRP 2 project High-Speed Nondestructive Testing Methods for Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings. There is no fee to attend this webinar or other webinars in the SHRP 2 Series; however, participants must register in advance. A certificate for 1.5 Professional Development Hours (PDH) will be provided to attendees who register and attend the webinar as an individual.

Register now.

The webinar will summarize 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)
• Greta Smith, American Association of State Highway and Transportation Officials (AASHTO)

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: Implementation strategies, tactics, and opportunities
• PART 4: AASHTO's perspective regarding the project
• PART 5: Question and answer session

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

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

• Select nondestructive testing technologies that improve inspection and detection and reduce traffic disruption;
• Describe test procedures and protocols to successfully implement those technologies; and
• Identify the types of implementation assistance that are available to agencies wishing to implement the nondestructive testing tunnel lining technologies.
