dc.descriptionTechnical Report-
dc.description.abstractThis effort was undertaken as a part of the Service Life Modeling of Aging Navigation Structures 6.1 basic research program. Due to the increasing required service life of our infrastructure, additional evaluation tools are necessary to determine whether concrete mixture designs will meet the higher levels of design requirements and useful life. Additionally, these tools may be used as predictive damage analysis techniques to evaluate when critical damage will occur, and potential remedies are applied to bring structures back into operation parameters. This report features non-destructive test methods, coring and petrography, and service-life-based sorption measurements to evaluate two existing navigation structures. Concrete sections and samples were evaluated for damage using multiple methodologies, and comparisons were made to attempt to correlate damage depth and mechanisms with the sorption data.en_US
