• Abstract:
  Performance Engineered Mixtures (PEMs) have been the primary focus of concrete mixture research on a national level for years. Tennessee has facilitated several projects over the years to move facets of PEM forward, including Enhancing Freeze-Thaw Resistance of Tennessee Concrete Mixes through Improved Air Void Testing (RES2020-09) and Determining Concrete Chloride Permeability Rapidly and Effectively (RES2013-41). Both research projects proved the viability of the Super Air Meter (SAM) and Surface Resistivity (SR) devices to some degree. This project served as a continuation of the data collection to attain a broader understanding of concrete mixtures utilized in Tennessee statewide. The resulting dataset has assisted TDOT’s Materials Control team in making determinations about where these devices the respective methods will fit in the sampling and testing program. This research project also served as an opportunity to develop and implement hands-on training with our Independent Assurance (IA) team members.
