Surface Chloride Levels in Colorado Structural Concrete

The Colorado Department of Transportation (CDOT) is investigating updates to its reinforcing steel corrosion protection strategies for structural concrete. In order for this to result in an efficient and economical policy, the Bridge Design and Management Branch needs to know how surface chloride levels vary at different structures around the state, with respect to differences in local climate, traffic volume, and location on the bridge. To be meaningful, chloride samples need to be taken from exposed locations on bridges with concrete similar to current concretes (built after 1978), take at a shallow depth sufficient to eliminate seasonal chloride variations. Data can be used to determine the appropriate corrosion protection strategies across the state.
