چکیده انگلیسی


• RAS was successfully used in field trials with warm mix asphalt, RAP, and ground tire rubber.
• RAS was successfully used as a replacement for fibers and asphalt in stone matrix asphalt.
• RAS mixes demonstrated acceptable fatigue and fracture properties in laboratory tests.
• The addition of RAP to a RAS mix design decreased its fracture energy at low temperatures.
• Larger RAS particle sizes increased the amount of pavement transverse cracking.

Transportation agencies have become increasingly interested in modifying hot mix asphalt (HMA) pavements with recycled asphalt shingles (RAS), yet they share common questions about the effect of RAS on the performance of HMA. In this study, the field and laboratory performance of RAS mixes produced from seven different transportation agencies are investigated as part of Transportation Pooled Fund TPF-5(213). Field demonstration projects were conducted that evaluated multiple aspects of RAS that include RAS grind size, RAS percentage, RAS source, RAS in combination with warm mix asphalt technology, RAS as a fiber replacement for stone matrix asphalt, and RAS in combination with ground tire rubber. Field mixes from each demonstration project were sampled and tested for their permanent deformation, fatigue cracking, and low temperature cracking performance. Recovered asphalt binder from each mix was also evaluated. Pavement condition surveys were conducted for each project after completion.
