Samenvatting
This synthesis documents the types of specifications and practices used by state trans-portation agencies to produce high performance concrete for bridges. The report also identifies specifications and practices reported as having improved concrete performance and those that have been less successful. Information used in this study was acquired through a review of the literature, a survey of state departments of transportation (DOTs), and follow-up interviews with selected state DOTs.
