Recycled Asphalt Shingles in Asphalt Mixtures with Warm Mix Asphalt Technologies

The objective of this research was to develop a design and evaluation procedure that provides acceptable performance of asphalt mixtures incorporating warm mix asphalt (WMA) technologies and recycled asphalt shingles (RAS), with and without reclaimed asphalt pavement (RAP), for project-specific service conditions. This research addressed the following issues: 1. Minimizing the risk of designing and producing mixes containing WMA technologies and RAS with poor constructability and durability; 2. Minimizing the risk of designing and producing mixes containing WMA technologies and RAS that are susceptible to premature failure; 3. Evaluating type, source, quality, and characteristics of RAS, with and without RAP; 4. Binder design and selection, including evaluation of the composite binder; and 5. The current range of asphalt mix production temperatures. The project final report will be published in the NCHRP Report series in the second half of 2018.
