Abstract
Corrosion of reinforced concrete piles located in a marine environment is of great concern, as it can reduce the load capacity of the piles and shorten their effective life. The Hampton Roads bridge and tunnel, located where the James River discharges into the Chesapeake Bay, was constructed with precast prestressed concrete piles, which have been exposed to a marine environment for 53 years. In the early 1980s, the Virginia Department of Transportation installed protective jackets on the piles to address the effects of chloride contamination and corrosion damage of the piles. The jackets were constructed by placing reinforcing mesh and a fiberglass stay-in-place form around an existing pile, and grouting the annular space with a mortar fill. The objective of these jackets was to prevent or mitigate corrosion activity by blocking water, oxygen, and chlorides from reaching the pile reinforcement. A study was undertaken to evaluate the effectiveness of the protective jackets through the use of visual evalua...
