Title: Core-Free Ultrasonic Technique For Evaluation of Concrete Pavements
Abstract: When deciding the most efficient way to rehabilitate concrete pavement, it is important to non-destructively evaluate the condition of the concrete. This paper presents the results of laboratory and field studies, aimed at examining the applicability of ultrasonic technology in evaluating concrete pavements. Various ultrasound tests have been proposed for concrete pavements. So far, however, ultrasonic testing has not found a wide application for testing of concrete pavements. This is mainly due to limitations in the equipment proposed. For example, most techniques require the use of fabricated specimens, or field cores. The method currently being developed would be a core free evaluation of the concrete pavement, on site. The results of laboratory testing and field testing of a closed off section of I-35 W demonstrate the potential of this technology with respect to concrete depth, dowel location, and concrete condition evaluation.
