Abstract:
The Oregon Department of Transportation has completed a bridge rehabilitation project using titanium bars. Girders on three of the four bridge spans of an overpass near Mosier, OR, were strengthened using a total of 70 titanium near surface mounted bars, a solution based on research conducted at Oregon State University. In addition to high tensile strength, ductility, and environmental durability, titanium offers high shear strength and resistance to mechanical damage, high maximum service temperature, and thermal expansion compatibility with concrete.
