dc.description.abstractDurability of bridge deck concrete may be defined as the ability of concrete to remain fully functional over an extended period under prevailing service conditions for the purpose for which it was designed. The durability of concrete structure is closely related to its permeability. The permeability dictates the rate at which aggressive agents can penetrate to attack the concrete and the steel reinforcement. Also, the most destructive weathering agent is the freezing and thawing of water in the concrete. During cold weather, pavements and bridge decks are subjected to freezing and thawing. For the purpose of removing the snow and ice, de-icing agents are applied, which causes the surface disintegration in the form of scaling and consequently, the chemicals accelerate the corrosion of reinforcement. This thesis is a part of a research project titled "Effects of Wet Mat Curing and Earlier Loading on Long-Term Durability 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. This thesis outlines the effect of curing on the chloride-ion Permeability and freeze-thaw resistance of different mix designs.
