This thesis is a part of a research project (project numer: 0-2116) titled "Effects of Wet Mat Curing and Earher Loading on Long-Term Durabihty of Bridge Decks" sponsored by Texas Department of Transportation (TxDOT). The project investigates the long-term effects of wet-mat curing duration and "early" loading on the durability of bridge decks (Phelan et al., 2001). Research tasks for the project include: (a) casting and monitoring of model deck slabs located across the state, (b) laboratory testing and (c) dynamic testing of the test bridge deck slabs. This research project is focused on the effect of reduced wet mat curing time and earher loading on long-term durability of concrete bridge decks. Research findings potentially will be used to update current wet mat curing and time-to-loading requirements in appropriate TxDOT specifications.
