Evaluation of Silica Fume High Density Thin Bonded Overlays
In September 1999, Bridges 'A' and 'B' of contract TBO1=0035-I(110)044 were overlaid with a silica fume concrete surface. ODOT has been exploring ways to stop or slow chloride-induced corrosion of uncoated reinforcing steel in bridge decks. Silica fume concrete additive had demonstrated success in reducing chloride intrusion. After one year of testing, the ride quality decreased slightly, skid test results showed adequate friction characteristics, and both bridges were in condition based on reinforcing steel corrosion activity. Overall, the silica fume modified PCC overlays are performing well.
