6 Field-Observed Cracking Of Paired Lightweight And Normalweight Concrete Bridge Decks, Tara L. Cavalline, Jeremy T. Calamusa, Amy M. Kitts, Brett Q. Tempest

Engineering Technology Faculty Publications

Research has suggested that conventional lightweight concrete can offer durability advantages due to reduced cracking tendency. Although a number of publications exist providing the results of laboratory-based studies on the durability performance of lightweight concrete (with lightweight coarse aggregate) and internally cured concrete (using prewetted lightweight fine aggregate), far fewer field studies of durability performance of conventional lightweight concrete bridge decks in service have been performed. This study was commissioned to provide insight to a highway agency on whether enhanced durability performance, and therefore reduced maintenance and longer lifecycles, could be anticipated from existing lightweight concrete bridge decks that were …
