Transportation research record, 2001•journals.sagepub.comThe principal reason concrete bridges deteriorate is that the reinforcement is damaged by
chloride-induced corrosion. Effective maintenance, for the most part, involves activities
designed to keep chlorides away from the reinforcement. Six maintenance activities help
accomplish this goal: flushing debris and chlorides from decks and pier caps annually,
repairing and sealing joints, sealing cracks, patching potholes, replacing the membrane if
replacing an asphalt overlay, and installing low-permeability overlays.
