ABSTRACT: Bridge decks do best with minimal cracking. This means using a low paste content (< 27% by volume), good consolidation, minimal finishing, and early and thorough curing. Many contractors don’t know how to do this. Concrete overlays should not be used in new construction. Finally, even with good materials and construction, you need corrosion resistant reinforcement if the deck is subjected to deicing chemicals.
