Increasing Bridge Deck Service Life

Increasing Bridge Deck Service Life
The Indiana Department of Transportation is funding this project with an objective of developing a bridge deck that has a service life of 75-100 years. To potentially improve the durability and performance of bridge decks, new types of alternative materials are evaluated. The alternative materials considered in this research are four different types of solid stainless steel (316LN, Duplex 2205, Duplex 2304, XM-28), MMFX II microcomposite steel, dual coated steel with zinc and epoxy, zinc-clad steel, and hot-dip galvanized steel.

The research addresses: 1) the bond behavior between alternative corrosion-resistant reinforcing steel and concrete, 2) the cracking performance, and 3) the corrosion resistance of alternative reinforcement.  A total number of 48 lap-spliced beam specimens, 12 slab specimens, and 112 modified macrocell specimens were designed, constructed, and tested to evaluate the structural and material performance of these new materials.
