Title: Corrosion-Resistant Steel for Longer Service Life and Lower Maintenance in Steel Girders
Project No.: 105168
Target Date: 06/30/2019

The Virginia Department of Transportation (VDOT) has transitioned from using coated steels in bridge-deck construction to uncoated, corrosion-resistant alloyed steel to reduce maintenance costs associated with corrosion in bridge decks.  This change has demonstrated that a primary factor for selecting bridge-deck steel should not be initial cost, but instead, the decision should be based on up-front costs plus future costs associated with steel maintenance operations. This project will compare the design requirements and fabrication of corrosion resistant steel girders with painted steel girders. This includes alloyed steel and galvanized weathering steel, both of which can improve the steel’s corrosion resistance and thus reduce maintenance costs. Upon the study’s completion, it is anticipated that its results will provide VDOT with a competitive product when compared to painted steel girders, which requires periodic repainting over the life of the structure.
