NYSDOT Seasonal Research Project
Modeling Mechanistic Properties of Unbound Materials for New York State
The Cornell Local Roads Program is conducting research on the seasonal variation of unbound pavement materials properties in New York State. This project will increase the applicability of the seasonal pavement materials models that were developed for the New York State Department of Transportation (NYSDOT) in an earlier research project Seasonal Variations of In Situ Materials Properties.
The models from that project were designed to help NYSDOT implement the new AASHTO mechanistic-empirical pavement design guide (DARWin-ME™) while still being applicable with the existing NYSDOT Comprehensive Pavement Design Manual (CPDM). This project will expand on earlier research results, creating models of seasonal change in unbound (subbase and subgrade) layer moduli applicable across approximately 90 percent of the area of New York State.
