Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
For concrete bridge decks, the use of salt in cold weather areas is known to result in damage, such as freeze or thaw damage (microcracks) and surface breaking cracks. In this paper attention is directed to an ultrasonic method to scan for surface-breaking cracks and to determine the crack depth in concrete bridge decks.
