Factors Affecting the Durablity of Concrete Bridge Decks: Summary
With the objective of determining factors which contribute to cracking of concrete bridge decks, projects were undertaken to explore the effects of different concrete strike off machines, effects of different timing of application of finish floating and texturing, effects of different methods and timing of concrete curing, and effects of different water contents in the concrete. Variations in the amount and location of the top layer of deck longitudinal reinforcing steel were investigated. Reinforcement placing and support techniques resulting in a flexible mat were compared to those resulting in a rigid mat. Flexible forms, absorbent forms, and forms with large gaps were compared with tight, rigid forms. Effects of air entrainment and a water reducing agent were investigated. The effects of thickening decks were studied, as were the advantages of using shrinkage compensated cement in the deck concrete. The effects of traffic were evaluated.
