Short-Term Field Evaluation of Spray-on Rejuvenators for Asphalt Pavement Preservation

Short-Term Field Evaluation of Spray-on Rejuvenators for Asphalt Pavement Preservation

Spray-on rejuvenators are pavement preservation treatments intended to mitigate oxidative aging of asphalt binder in the nearsurface region of asphalt pavements. Although several highway agencies have evaluated these treatments, reported performance outcomes vary, and the Virginia Department of Transportation (VDOT) has limited documented experience with their use. Prior to this study, VDOT did not have an established specification or standardized evaluation framework for spray-on rejuvenators. This study was conducted to evaluate the feasibility and short-term field performance of spray-on rejuvenators under Virginia conditions and to support the development of guidance for potential future implementation. The scope included a comprehensive review of published literature, agency specifications, and state-of-practice documents, along with field trials conducted in the Lynchburg and Northern Virginia districts. Following completion of the Lynchburg District field trials, a special provision was developed to guide spray-on rejuvenator application practices and was implemented for the Northern Virginia District field trials.
