Test Methods for Verification of Low-Temperature Cracking Resistance of Asphalt Binders and Mixtures

The objective of this research is to identify and, if necessary, refine binder and mixture tests capable of addressing low temperature and reflection cracking in Minnesota asphalt pavements. The tests should provide a distinction between brittle and ductile behavior at low temperatures to identify cracking susceptibility, be relatively simple to perform in standard agency and contractor laboratories, require minimal time to perform and return results, and be repeatable and reproducible.
