Remote Sensing Techniques for Bridge Deck Evaluation

The medical field has been very successful in utilizing non-invasive diagnostic techniques to identify conditions in the human body. The popularity and acceptance of Ultrasonic, X-ray, Magnetic Resonance Imaging, Thermographic, Tomography and various other similar innovative techniques have grown many folds since their initial application many years ago. Unfortunately, the engineering field has lagged way behind in applying similar technologies to perform non-destructive evaluation of structural conditions mainly because of the bulky and expensive nature of some of these equipments. However, as the technologies and manufacturing techniques have matured over the years, the uses of non-destructive techniques for engineering evaluations have seen a significant growth in the last few years. This paper presents a case study in application of a non-destructive remote sensing technique to evaluate the condition of a bridge deck. The investigation included combined applications of Infrared Termoghraphy and Ground Penetrating Radar. A comparison of existing deck core results obtained earlier and IR/GPR results from this investigation indicated good correlation. The paper also presents a methodology to establish an equivalent 28-day compressive strength (f’c) for old concrete for use in the rehabilitation design of the structure and a procedure for evaluating the quality of the concrete.
