EVALUATION OF THE USE OF LASER ULTRASONICS FOR THE RAPID, NONCONTACT INSPECTION OF CONCRETE AND ASPHALT
This report documents the investigation of the use of a laser system for the detection of voids, delaminations, and defects in asphalt and mesh reinforced concrete structures. The goals of the research were to discover whether laser systems could: generate and receive ultrasound in concrete asphalt; verify that such a system obtains the same information as conventional ultrasonic tests; see if laser system could obtain more information than conventional tests; and consider how laser ultrasonics would be used in the field.
