The ability to evaluate infrastructures without altering or damaging the structure is becoming increasingly important and useful for infrastructure maintenance. The technique to analyze and test materials for weaknesses without causing destruction is referred to as non-destructive evaluation or testing (NDT&E). Specifically, a common method of this type of inspection is called ground penetrating radar (GPR), which is desired in many construction applications. With the use of electromagnetic energy, GPR has the capability to locate buried objects in materials because of the differences in electrical and magnetic properties that are encountered. Valuable data can be obtained on these subsurface objects, allowing for an understanding on the properties and making proper judgment on the structure possible. This study explores the approaches in which GPR has been implemented for the assessment of the bridge deck in the southeast United States. Through different data acquisition and processing techniques, results show that GPR is very successful in collecting information to verify the state and condition of these materials.
