Laboratory Study: Laboratory Testing of Bridge Deck Mixes
The purpose of this investigation was to develop bridge deck mixes that will improve field performance and minimize cracking potential compared to Missouri Department of Transportation's (MoDOT) current (B-2) bridge deck mix design. The mix designs developed in this study were tested and compared to the control B-2 mixes for strength, durability, permeability, and shrinkage potential. This paper presents laboratory test results from nine different concrete mix designs that will be considered by MoDOT's bridge deck quick action (QA) team to replace the current bridge deck mixes. The mixes differed mainly by the amounts and combinations of supplementary cementitious materials, which included Class C flyash, ground granulated blast furnace slag (GGBFS), silica fume, and ternary combinations of these materials. The research conducted should give MoDOT a bridge deck mix that is more economical, increases the service life, and reduces the maintenance costs of bridge decks in the future.
