APPLICATIONS OF THE IMPACT-ECHO METHOD FOR DETECTING FLAWS IN HIGHWAY BRIDGES

Engineers involved in the evaluation, repair, and rehabilitation of concrete bridges have long had a need for nondestructive test methods which can provide information about the internal condition of a structure without the need to drill holes into the structure. The impact-echo method -- a versatile and powerful technique that can detect internal flaws in a wide variety of reinforced prestressed concrete bridges -- is rapidly becoming an extremely useful tool for engineers involved in condition assessment situations. This paper provides a brief explanation of the impact-echo method and describes a variety of case studies where the method has been used effectively for condition assessment of bridges.
