• Abstract:
  The main purpose of the proposed research is to develop a mix design procedure for high RAM mixtures with both rejuvenators and fractionated RAM materials for Iowa DOT and local public agencies by thoroughly understanding complex interactions between fractionated RAM and rejuvenators. Main objectives of this research are to: 1) examine the effects of various rejuvenators and different methods of RAP stockpile fractionation on the volumetric mix design properties, 2) evaluate long-term oven aging of both 4 laboratory and field rejuvenated/fractionated high RAM mixtures and 3) develop specifications for evaluating asphalt mixtures with rejuvenators and high fractionated RAM contents.
