• Abstract:
  Like many other state highway agencies, the Virginia Department of Transportation is extensively working to consider how to best incorporate recycled materials—such as recycled plastic, reclaimed asphalt pavement (RAP) at higher contents with and without the use of recycling agents (RAs), and other materials—into their roads while maintaining or improving durability. The purpose of the study was to determine if recycled plastic-modified (RPM) asphalt mixtures and high RAP (HRAP) mixtures with RAs require deviation from current practice. The first objective of this research was to evaluate whether the design, production, and paving of RPM asphalt mixtures require a change in current practice. The second objective was to ascertain if the production and paving of RPM mixtures result in the generation of hazardous emissions to the environment. The third objective of the study was to assess if higher RAP content mixtures (RAP content > 30%) containing RAs can be designed, produced, and paved to meet relevant performance specifications. Finally, the study evaluated the short-term performance of RPM mixtures and HRAP mixtures containing RAs.
