Abstract:

Rises in construction and asphalt binder costs, as well as the growing pressures on landfills, have contributed to the ; increased use of tear-off scrap shingles (TOSS) and manufacturer waste scrap shingles (MWSS) into hot-mixed ; asphalt (HMA) pavement mixtures. This research project was undertaken to address the responsible incorporation ; of recycled asphalt shingles (RAS) into HMA pavement mixtures to ensure environmental benefits are realized and ; pavement durability is retained or improved. ; The research consisted of a literature review, extensive laboratory testing and field evaluations of in service ; RAS/RAP HMA pavements. Binder testing established a strong correlation between the new asphalt binder to total ; asphalt binder ratio and the extracted high/low binder performance grade temperatures. Dynamic modulus testing ; on HMA mixtures proved to be an invaluable tool in comparing the effects of RAS and RAP on mixture properties ; across a wide range of temperatures. Field performance appeared to validate the laboratory findings in some ; instances.
