Assessment of highway bridge coatings has been primarily through visual inspection
and destructive testing. This project sought to produce the first quantitative,
non-visual nondestructive evaluation tool for bridge coatings for United States Department of Transportation (USDOT)
Small Business Innovative Research (SBIR) Project DTRT57-15-C-10043. This Phase
IIB project was conducted from September 25, 2015 to December 25, 2018.
The Phase II project DTRT57-11-C-10010 was conducted from February 22, 2011 to
August 21, 2014. The Phase I project DTRT57-09-C-10040 was conducted from
July 21, 2009 to January 21, 2010.

The technical objective of the project was to develop a nondestructive evaluation
(NDE) tool for quantitative assessment of highway bridge coatings. During the
project three significant innovations for the measurement of highway bridges and
other structures were developed. These innovations provide new ways to inspect
and assess structures, providing types of information that did not previously
exist. These three significant innovations are 1) an entirely new method to
assess and inspect coatings, 2) an entirely new method to assess large concrete
structures, and 3) an entirely new method to assess stress distributions in steel
structures.
