Comprehensive Bridge Deck Deterioration Mapping of Nine Bridges by Ground Penetrating Radar and Impact Echo

Iowa Department of Transportation (IDOT), like many other State Departments of Transportation (DOTs), is faced with the need of identifying and deploying means for rapid, nondestructive and accurate condition assessment and performance monitoring of bridge decks. Finding the right technologies will make a tremendous difference in the financial resources spent for their renewal. The data collected from nondestructive testing (NDT) of bridge decks should complement other information in understanding of its lifecycle costs, deterioration mechanisms, and the effectiveness of preservation techniques at various stages of the aging process, and most importantly, prevent premature and unexpected failure. One of very important objectives in the design of the testing program will be to ensure that the NDT methods used can cover the entire lifespan of a concrete bridge deck. There are two main objectives of the proposed bridge deck evaluation: (1) Demonstrate capabilities of NDT, Ground Penetrating Radar (GPR) and IE in particular, in condition assessment and monitoring of bridge decks, and (2) Evaluate and describe condition of the nine bridge decks proposed by IDOT. Such an evaluation will be of benefit to the IDOT for both future selection of technologies of the highest interest, and for raising the confidence level regarding the long term application of the selected technologies in project and network level bridge deck evaluation.
