Abstract:

In September 1999, Bridges "A" and "B" of contract TBOI-0035-1(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 has demonstrated success in reducing chloride intrusion. After one year of testing, the ride quality decreased slightly, skid test results show an adequate amount of friction characteristics, and both bridges in good condition based on reinforcing steel corrosion activity. Overall, silica fume modified PCC overlay is performing well.
