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.
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, user’s guide are available for download in a single ZIP formated file.
