Durability of Concrete Bridge Decks with Reduced Reinforcement

Dagher, H. / Hamilton, W. / Kulendran, S.

Abstract The premature deterioration of concrete bridge decks in regions where deicing chemicals are used has created a multi-billion dollar problem in the United States. In this paper, a simple method to extend the life of new concrete bridge decks is explored: the reduction of deck reinforcement. When a reinforcing bar corrodes, its volume will increase, and eventually, the surrounding concrete will crack. With less steel, there will be less material corroding and expanding, and a longer deck life may result. Rather than attempt a precise proof for this thesis, a number of supporting arguments are made. An approximate procedure to estimate the possible gains in deck life resulting from reduced reinforcement is described. The procedure is based on a smeared-cracking finite element model.
