Project description

The objective of this research is to evaluate accuracy of test methods for measurement of air content in fresh concrete in comparison to air content in the hardened concrete of the same type, and to determine the hardened air content and air void dispersion in concrete pavement. The results will recommend proper method and procedure to determine air content in fresh concrete, recommend values for concrete properties to be used in the Standard Specifications and the applicable Standard Special Provisions, and to report potential changes in practice and benefits in terms of performance and cost savings.
