Abstract:

Asphalt pavement technology has been driven by a desire to reduce the consumption of virgin oil ; products and improve the sustainability of vital ingredients required to produce pavement. The goal of ; the research study described in this report is to develop a strategy to select the type/quantity of recycled ; material, and PG grade for the virgin binder, of an asphalt mix to provide optimum performance in a ; given environment. This study compared the performance one mix design with five different quantities ; and combinations of recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) using an ; Asphalt Mixture Performance Tester (AMPT). Three different PG graded binders were utilized. ; Based on the measurements of dynamic modulus and phase angles from the AMPT, it was concluded ; that a high RAP mixture with a soft binder grade could perform similarly to a low RAP mixture with a ; harder binder grade. Mixtures using RAS have different performance characteristics than those using ; RAP only. These mixtures were less susceptible to changes in loading frequency and temperature.
