TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R06G-RR-1: Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings identifies techniques that appear to provide useful information for evaluating tunnel linings.
The results of Renewal Project R06G were incorporated into an electronic repository for practitioners, known as the NDToolbox, which provides information regarding recommended technologies for the detection of a particular deterioration.
This work was sponsored by the Federal Highway Administration in cooperation with the American Association of State Highway and Transportation Officials. It was conducted in the second Strategic Highway Research Program, which is administered by the Transportation Research Board of the National Academies.
The team sincerely thanks the following individuals for allowing the team to test in their tunnel facilities and for their assistance:
The team also thanks the expert panel for this project. The panel members were:
Mapping Voids, Debonding, Delaminations, Moisture, and Other Defects Behind or Within Tunnel Linings
In conjunction with the R06G Report, three separate products were created: a user’s manual, which provides information on three nondestructive testing (NDT) technologies for tunnel inspection; analysis software called Tunnelcheck; and a brief user’s guide to the software.
The user's manual, software, and user's guide are available for download in a single ZIP formated file (121 MB).
