Project description

This research examined and documented the use of internal curing by superabsorbent polymer (SAP) to improve the durability of Tollway bridge decks. The project included laboratory studies to characterize material behavior and properties, and field testing to measure slab performance and observe behavior with full scale truck mixers.
