Evaluation of Cold Central Plant Recycling (CCPR) for Airport Use

The Airport Pavement R&D section is collaborating with the Airport Asphalt Pavement Technology Program on a project to evaluate a recycled pavement technology called Cold Central Plant Recycling (CCPR) for airport use. This method involves milling old asphalt pavement and processing it in a plant without applying heat, unlike traditional asphalt methods. During CCPR, a new liquid asphalt binder and a small amount of cement are added before the materials are reapplied to the roadway or runway. The project team includes pavement experts from the University of California, Davis, the National Asphalt Pavement Association, the Virginia Department of Transportation, and paving contractor Allan Myers Inc. The CCPR pavement will be installed at the National Airport Pavement Materials Research Center, where the FAA will use the Heavy Vehicle Simulator for Airfields to simulate aircraft wheel loads on the pavement.
