Abstract:

The Maryland Department of Transportation State Highway Administration (SHA) is currently using Ground Penetrating Radar (GPR) for assessing the condition of bridge decks (such as surface condition, rebar cover depth and location, and deck thickness). In the last year SHA initiated a task to survey eighty (80) bridge decks using 3D GPR. The equipment for the task included the 3DRadar DX 1821 and DXG1820 antenna array, a MkIV Geoscope, and 3dr Examiner Pro software. The equipment was procured from 3D-Radar (Chemring) and the Maryland Environmental Service (MES) provided the data collection and initial analysis. The university team provided overall project management and kept continuous interaction with SHA throughout the duration of the project in order to meet the project objectives and to obtain administrative and technical feedback. The technical reports reflecting the GPR data analysis for the 40 bridge decks were completed by the team. It was concluded that GPR can be used to monitor changes in bridge deck condition immediately after construction for quality assurance and acceptance testing, and provide the base line for potential time series analyses. This will enable long term rigorous performance monitoring of bridge decks for planning, maintenance, and rehabilitation activities.
