Develop/Improve American Association of State Highway and Transportation Officials Concrete Coefficient of Thermal Expansion Test

The project concerns ruggedness and precision evaluation and assistance in the deployment of American Association of State Highway and Transportation Officials Coefficient of Thermal Expansion Testing Equipment for Concrete Cores and Cylinders. It involves participation in Ruggedness and Precision Studies on the Various Coefficient of Thermal Expansion Equipment Options; Pine, Gilson, Manual (endpoint and length-change curve evaluation). It also calls for addressing the needs of the Mechanistic-Empirical Design Guide for accurate characterization of the thermal properties of the concrete—as affected by the materials and mixture proportions—for Concrete Pavement Road Map Track 2 research on the design guide and Subtrack MD 2.8 of Concrete Pavement Road Map Track 1—Portland Cement Concrete Mixture Thermal Tests: Coefficient of Thermal Expansion advancement and other thermal testing if needed. Coefficient of Thermal Expansion has been found to be a very important factor in the performance of concrete pavement, and having more accurate Coefficient of Thermal Expansion values for the actual mixture will improve the accuracy of performance predictions and evaluations of concrete pavement sections. During ruggedness testing, specimens will also be used to look at concrete materials and age effects and to compare the Texas/California slope data versus the current American Association of State Highway and Transportation Officials' endpoint technology.
