Like many states, the State of Washington has struggled with performance and serviceability of cast‐in‐place concrete bridge decks. WSDOT recently hired Washington State University (WSU) to study bridge deck cracking. These materials describe WSDOT’s deck cracking issues and the research from WSU, focusing on the performance concrete mix design and the recently‐completed pilot project.
