Aging Characteristics of RAP Binder Blends―What Types of RAP Binders Are Suitable for Multiple Recycling?

Recycled asphalt pavement (RAP) is commonly used due to its environmental and economic advantages; however, how RAP responds to oxidative aging has been a major concern in the development of a selection criterion for virgin and recycled asphalts. In this study, the authors seek to determine the chemical and rheological properties as a function of oxidative aging at pavement service temperatures in RAP and RTFO virgin asphalt blends for the case where all of the RAP is used in blending.
