Using Reclaimed Asphalt for Pavement Preservation Surface Treatments

At the end of 2020, the Federal Highway Administration (FHWA) released a new report that outlines the success of using Reclaimed Asphalt Pavements (RAP) in pavement preservation treatments. The FHWA documented case studies, best practices, applicable tests, costs and specifications for RAP in pavement-preservation treatments, such as chip sealing, slurry sealing and microsurfacing.

Greg Duncan, senior engineer at Applied Pavement Technology, Inc., recently presented a webinar with the FHWA and described how agencies and practitioners have adapted typical practices to get similar performance with RAP as compared to virgin aggregates with preservation treatments.
