A010 Applicability and Limitations of Impact Echo in Bridge Deck Condition Monitoring P. Shokouhi * (The University of Texas at El Paso (UTEP)) N. Gucunski (Rutgers University) & A. Maher (Rutgers University) SUMMARY Near Surface 2006 — Helsinki Finland 4 - 6 September 2006 One of the most common problems in concrete bridge decks is a corrosion-induced deck delamination. A number of nondestructive testing (NDT) techniques have been utilized to map delaminated zones in concrete bridge decks (Scott et al. 2003). Impact echo (IE) an ultrasonic seismic method has proved successful in detection of delaminations in concrete bridge decks at
