• Abstract:
  The Washington State Department of Transportation (WSDOT) revised the concrete ; specification for bridge decks in 2011 to be more performance based with the desired effect of ; having less early-age shrinkage cracking. This report evaluates a sample of the bridges ; constructed with the revised performance based specification against a sample of bridges ; constructed with the traditional WSDOT specification. The evaluation consists of visual ; inspections, noting cracks and developing crack intensity diagrams for each bridge. These ; diagrams are then used to rank and compare the bridge decks. The outcome of this study is that ; the bridge decks constructed with the performance based specification have much less early-age ; shrinkage cracking then the traditional WSDOT specification.
