Characterization of Wisconsin Mixture Low Temperature Properties for the AASHTO Mechanistic-Empirical Pavement Design Guide. Final Report 2009-2011

摘要

This research evaluated the low temperature creep compliance and tensile strength properties of Wisconsin mixtures. Creep compliance and tensile strength data were collected for 16 Wisconsin mixtures representing commonly used aggregate sources and binder grades. Engineering and statistical analyses were performed on the data to provide recommendations for using measured mechanical properties in thermal cracking analyses with the Mechanistic- Empirical Pavement Design Guide (MEPDG), and to evaluate the thermal fracture resistance of Wisconsin mixtures.
