Civil infrastructure systems such as highways and bridges represent the skeleton of any nation. The condition of the transportation infrastructure in the United States is aging and deteriorating, and requires huge financial and human resources for its rehabilitation and maintenance. If a damaged element remains undetected, the structural integrity and serviceability of the bridge would get worse over time. Therefore, monitoring bridge conditions is extremely crucial for keeping bridges in good condition. A bridge deck is one of the main elements of the superstructure of a bridge. A bridge deck evaluation includes an inspection report, recommendations for repairs and estimated budgetary costs for each of the repairs. It will also prioritize the repairs, so that with fund limitation, the most pressing issues can be done first. Several Non-Destructive Testing (NDT) techniques have been developed to evaluate bridge condition accurately and effectively. NDT techniques have the potential to quickly and reliably provide the needed information about under-the-surface conditions and material properties of bridge deck. But independent evaluations are needed to determine their best use and to validate their effectiveness under a variety of conditions. In this study, a review of different types of NDT techniques for bridge decks, their applications, performance, limitations, equipment and test procedures are presented. Also, recommendations regarding the best techniques for a particular application are provided. The outcome of this study is to get a better understanding of strengths and limitations of bridge inspection techniques in defects and mechanical properties of concrete bridge decks evaluation. The results can be beneficial for transportation agencies to select inspection methods properly and effectively.
