Investigation of the impacts of aging and RAP percentages on effectiveness of asphalt binder rejuvenators

Completion Date: 2016

Funding Agency: The New Jersey Department of Transportation (NJDOT)

Abstract: The objectives of this project included: (a) evaluating the ability of different asphalt binder rejuvenators, originating from various sources, to lower the Performance Grade (PG) of aged binders contained in RAP materials, (b) investigating the impact of asphalt binder aging time and RAP material percentages on the ability of five asphalt binder rejuvenators in restoring low and high temperature grades of aged RAP binders; and, (c) evaluating the impact of different rejuvenators on mechanical properties over a broad range of temperatures and frequencies.
