Infrasense Evaluates the Condition of Claiborne Pell Bridge Deck in Rhode Island
Infrasense has carried out evaluations of an approximately 2-mile section of bridge decks belonging to a signature Rhode Island bridge. A combination of ground-penetrating radar (GPR), high-resolution visual (HRV), and rapid automated sounding (RAS) methods were utilized for this expansive project. Rebar depth, concrete deterioration, and other signs of delamination were identified to provide recommendations for further rehabilitation. NEWPORT, R.I. /PRNewswire/ — The objective of this project was to evaluate the condition of two sections of the bridge deck of a ~2-mile-long signature bridge near Newport, Rhode Island. This evaluation involved using a combination of ground penetrating radar (GPR) and high-resolution visual (HRV) methods, along with rapid automated sounding (RAS) for additional delamination information. The GPR data was collected using a dual horn antenna vehicle-based system at normal driving speeds and in a series of lines spaced 3 feet transversely across the ...
