Over the past years, a remarkable number of bridges have been collapsed or failed worldwide, underlying the growing importance of condition assessment of bridge structures within the context of health monitoring of structures and their life cycles become important to prevent such events. If utilised correctly, advanced Non-Destructive Techniques (NDTs) have proved to be effective in detecting imperfections such as bridge deck delamination, crack formation, and rebar corrosion. This paper presents the benefits of using Augmented Reality (AR) technology, applied combined, with visual inspection, Ground Penetrating Radar (GPR), Laser Distance Sensors (LDS), Infrared Thermography (IRT), and Telescopic Camera (TC). Using this approach, a bridge was investigated for weaknesses such as cracks and rebar corrosion. The methodology implemented in this paper can enhance structural engineers and/or asset manager's decision making, related to applying advanced NDT to dynamically affected bridges.
