\t\t\t\tAbstract:<\/strong><\/p>\n

Reclaimed\u00a0Asphalt Pavements (RAP) and Recycled Asphalt Shingles (RAS) are increasingly used in asphalt concrete\u00a0(AC) pavements\u00a0due to\u00a0their lower\u00a0initial cost and potential sustainability benefits. Despite these benefits, the use of these materials poses significant challenge\u00a0as the recycled\u00a0binder available in these materials\u00a0is\u00a0highly oxidized due to\u00a0aging. This makes asphalt binder brittle\u00a0and becomes a driving factor for cracking related distresses. In order to improve the performance of\u00a0AC mixtures\u00a0with\u00a0RAP and RAS recycled\u00a0materials, rejuvenators are used to\u00a0modify the oxidized binder rheology\u00a0and chemistry. Rejuvenators can be used in virgin binders to reduce the impact of increased stiffness or can be mixed directly with RAP\/RAS stockpiles.<\/p>\n
