• Abstract:
  The percent of reclaimed asphalt pavement (RAP) used in hot mix asphalt (HMA) is currently established either by arbitrarily setting maximum percent limits, or alternatively, by evaluating both the virgin and recovered binder properties. The first approach is based on engineering judgment and historical experience but is not quantitative. The second assumes that there is a linear change in binder properties between 0% and 100% RAP. It also consumes extensive amounts of time and solvents in the process of obtaining and testing the binder properties. The purpose of this research program is to develop a fundamentally sound, easily implemented non-solvent based test method for assessing performance-based binder properties using standard gyratory-compacted asphalt concrete mix samples.
