Project Details

Project Description: 

The contractor will evaluate (but is not limited to) the following: chloride concentration; humidity; industrial pollutant levels; temperature; time of wetness; and geometric factors, such as horizontal and vertical clearance, that may cause poor weathering steel performance. It is envisioned that project success will rely heavily on field performance evaluation of a sample of weathering steel bridges from across the entire United States. The contractor is expected to apply simple and meaningful test protocols, which can be used to define the macroenvironments and microenvironments, that influence weathering steel performance. In addition, the contractor shall document the relevant bridge geometric factors.

Goals

To better understand the macroenvironments or microenvironments and the geometric design variables that influence the corrosion performance of weathering steel.
