Project description

Missouri Department of Transportation (MoDOT) has been very methodical and consistent with bridge deck ratings, it would be great to look at progression of silane bridge deck ratings since MoDOT moved to silane sealers 10-15 years ago. The research would determine if deterioration has slowed. MoDOT now uses 100% silane and have been told that decks with 100% silane only need to be sealed once and never again. This project will look at that claim to determine if it is accurate that MoDOT would never seal again, or if not if the frequency of reapplication can be reduced.
