Rebar and the Alvord Lake Bridge (2013)
- dugditches 11y agoThe biggest issue is the bridge decks. Epoxy rebar is a gaff. Any knicks or marks damage the coating. Stainless steel is gaining speed but is very expensive. And recently Carbon Fibre bar has been entering the market.
- mannykannot 11y agoI vaguely remember an item on TV about how the Oregon DOT was protecting some of its historic bridges by spraying zinc on to the concrete and then applying a voltage between it and the rebar to counter or reverse the corrosion. This paper mentions the technique. http://www.oregon.gov/ODOT/HWY/REGION2/docs/area5/Cathodic%20protection.pdf http://www.oregon.gov/ODOT/HWY/REGION2/docs/area5/Cathodic%2...
