This report summarizes performance monitoring activities and evaluation in conjunction with the experimental use of shrinkage compensating bridge deck concrete (Class s). Two bridges of similar design but constructed using Class AA concrete were monitored for comparison purposes. due to the absence of significant shrinkage cracking on the comparison bridge decks and the presence of minor shrinkage cracking on the Class S bridge deck, no conclusions were apparent at this time. Further study may quantify the reduction of shrinkage cracking due to the use of shrinkage compensating concrete in bridge decks.
