• Abstract:
  The primary objective of this research was to demonstrate the benefits of NDT technologies for effectively detecting ; and characterizing deterioration in bridge decks. In particular, the objectives were to demonstrate the capabilities of ; ground-penetrating radar (GPR) and impact echo (IE), and to evaluate and describe the condition of nine bridge ; decks proposed by Iowa DOT. The first part of the report provides a detailed review of the most important ; deterioration processes in concrete decks, followed by a discussion of the five NDT technologies utilized in this ; project. In addition to GPR and IE methods, three other technologies were utilized, namely: half-cell (HC) potential, ; electrical resistivity (ER), and ultrasonic surface waves (USW) method. The review includes a description of the ; principles of operation, field implementation, data analysis, and interpretation; information regarding their ; advantages and limitations in bridge deck evaluations and condition monitoring are also implicitly provided.. The ; second part of the report provides descriptions and bridge deck evaluation results from the nine bridges. The results ; of the NDT surveys are described in terms of condition assessment maps and are compared with the observations ; obtained from the recovered cores or conducted bridge deck rehabilitation. Results from this study confirm that the ; used technologies can provide detailed and accurate information about a certain type of deterioration, electrochemical ; environment, or defect. However, they also show that a comprehensive condition assessment of bridge decks can be ; achieved only through a complementary use of multiple technologies at this stage,. Recommendations are provided ; for the optimum implementation of NDT technologies for the condition assessment and monitoring of bridge decks.
