Project description

Nondestructive evaluation (NDE) technologies have the potential to inform bridge deck managers of conditions that cannot be obtained by simple visual analysis of bridge decks or from a single summary score like the National Bridge Inventory rating. NDE tests for bridge decks are usually time-consuming and labor-intensive evaluations due to the large size of structures, especially for point test methods such as impact-echo and ultrasonic tests. Automated NDE techniques using robotics have been proposed and developed in recent years.
