Evaluation of Performance of A1010 Bridge Steel, RB10-016

In 2016, the Iowa Department of Transportation (DOT) plans to build a bridge in Woodbury County (County Road K-25 over 129) with a 4-span bridge partially constructed using ASTM A1010 bridge steel. A1010 steel is a relatively new to the market structural stainless steel. ASTM A1010 bridge steel is a nominal 12% chromium (10.5% minimum, 12.5% maximum) material that is reported to have enhanced corrosion resistance over that of traditional painted structural steels, weathering steels, and galvanized steels. A1010 steel has been successfully used in environmentally aggressive applications such as coal rail cars and coal processing equipment just to name a few. Although more expensive initially, it may be possible that bridges constructed using A1010 may have longer service lives and, therefore, lower overall lifecycle costs. The general goal of the work proposed here is to evaluate the fundamental behavior of girders fabricated using A1010 steel, to evaluate the potential for galvanic corrosion when various fastener types are used, and to evaluate the in-situ performance of the Woodbury County Bridge.
