Performance of 20 chloride-contaminated, partially restored, waterproofed bridge decks was evaluated for three years. Annually, surface conditions were mapped, extent and location of delaminated areas were determined, waterproofing permeability was measured, and attempts were made to determine the rate of corrosion. Insufficient service life performance data were available to determine if sealing surface of partially restored chloride-contaminated decks will affect the rate of deterioration. Voids or blisters were found in the waterproofing system. Delaminations could not be distinguished from blisters. Results of corrosion measurements were inconclusive. The waterproofing membrane prevented penetration of surface moisture.
