Project description

This project will develop a database with Portland Cement Concrete (PCC) materials characterization data necessary for Idaho Transportation Department (ITD) use of American Association of State Highway and Transportation Officials Ware (AASHTOWare) Pavement Mechanistic-Empirical (Me) Design for PCC pavement design. This will be accomplished by characterizing materials used in PCC pavement by the Idaho Transportation Department. Types and proportions for main constituents of concrete paving mixtures across Idaho will be identified. Material from suppliers throughout the state will be gathered and tested for drying shrinkage, mechanical properties and indirect split tensile. A PCC-Me Database will be developed using the material testing results. The implementation of the new Pavement Me Design Guide will provide more economical pavement structures saving Idaho money.
