Dept. of Transportation. Bureau of ResearchUnited States. Federal Highway AdministrationUS Transportation CollectionThis report describes work on laboratory and field performance reviews of an ultrasonic shear wave imaging device called MIRAfor application to plain and reinforced concrete infrastructure components. Potential applications investigated included bridgedeck delamination detection, deck thickness profiles, and detection of internal steel bars and dowels. Based on the observedperformance of the unit, three classification categories of applications were defined: field ready, potentially ready, andchallenging. In general, the MIRA device is not well suited to provide full-coverage rapid scans over an entire structure. RatherMIRA is more suited for targeted inspection or failure analysis to determine general geometric and internal features of concreteelements because MIRA is able to be quickly deployed for spot inspections with little site preparation. A user\ue2\u20ac\u2122s manual wasproduced to assist in introducing new users to the proper operation and interpretation of the MIRA device
