N2 - This paper presents a case study of inspection and evaluation of a concrete bridge located in southeast Texas. A significant level of deterioration of concrete columns in the bridge has generated public concerns regarding its structure integrity. Many environment-related factors (including erosion, abrasion, wetting/drying, carbonation, freezing-thawing, chemical attack, and microbial-induced deterioration) could all contribute to the deterioration. In this study, a visual inspection and a number of field tests were performed on columns of the bridge. Nondestructive evaluation (NDE) - including hammer sounding, rebound hammer, ultrasonic pulse velocity, covering thickness, and half-cell corrosion potential analyses - were performed in the comprehensive study to determine cause(s) of concrete degradation and TO ascertain the degree of deterioration.
