Acoustic emission is one of an ensemble of methods for the condition assessment of fracture critical bridge members. This inspection method provides a unique input to risk-informed maintenance management and planning and to prescribe maintenance follow up actions with major financial implications. Knowledgeable bridge owner/operators over the last thirty years have used acoustic emission in over 500 bridge applications worldwide; wherein acoustic emission experts provide input into
their engineering and economic planning consistent with established codes and standards. This paper outlines the acoustic emission approach and its application in bridge risk-informed maintenance management.
