Understanding and Improving Heterogeneous, Modern Recycled Asphalt Mixes

The research goal will be to focus on high-type mixes (Missouri Department of Transportation (MoDOT) Sec. 403 mixes), although findings will provide useful insight for all asphalt mixes used in Missouri. A comprehensive suite of binder and mixture tests will be carried out in order to link mix designs and materials to eventual field performance (rutting, cracking, and moisture damage predictions). This project will allow the study team to evaluate the potential performance of modern crumb rubber mixes, reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) mixtures, and rejuvenators in Missouri.
