This study evaluated the laboratory and field performance of asphalt mixtures containing reclaimed asphalt pavement (RAP) with the use of a compaction aid and a bio-based recycling agent. Two dense-graded mixtures with a nominal maximum aggregate size (NMAS) of 9.5 mm were designed using a PG 64-22 virgin binder. These mixtures differed in RAP content: one with 30% RAP (control, with compaction aid) and another with 45% RAP (incorporating a bio-based recycling agent). Initial volumetric mix designs (VMD) were developed following the Virginia Department of Transportation (VDOT) specifications. The optimum binder and recycling agent contents were then adjusted based on the VDOT provisional balanced mix design (BMD) framework to meet the cracking threshold determined by the Indirect Tensile Asphalt Cracking Test (IDEAL-CT) while maintaining rutting resistance in the Asphalt Pavement Analyzer (APA). Following laboratory design, both mixtures were produced at an asphalt plant and placed at the National Center for Asphalt Technology (NCAT) Test Track for long-term evaluation under heavy truck traffic. After approximately 24 million equivalent single axle loads (ESALs), both sections exhibited rut depths below 10 mm and less than 5% surface cracking, well below the 20% cracking limit established for the Test Track. Ride quality and surface texture also remained stable throughout the monitoring period. Overall, the results highlight the effectiveness of a bio-based recycling agent in achieving balanced performance and enabling higher RAP utilization within a BMD framework.
