I-81 In-Place Pavement Recycling Project
During the 2011 construction season, the Virginia Department of Transportation (VDOT) completed an in-place pavement recycling project to rehabilitate a section of pavement on I-81 near Staunton, Virginia. The project consisted of a 3.66-mile section of southbound I-81 in Augusta County. VDOT employed three in-place pavement recycling techniques and a unique traffic management plan to accomplish the work. The recycling processes included full-depth reclamation (FDR), cold in-place recycling (CIR), and cold central-plant recycling (CCPR). This project marked the first time in the United States that these three recycling techniques were combined in one project on the interstate system. Materials for both the CIR and CCPR were produced using hydraulic cement and foamed asphalt. A combination of hydraulic cement and lime kiln dust was chosen for the FDR process. The purpose of this research portion of this construction project was threefold: (1) to allow VDOT personnel to gain experience with the specific laboratory mix designs, field evaluation, and quality assurance procedures; (2) to characterize the structural properties of the materials used in the recycling project; and (3) to document the performance of the entire rehabilitated section during its initial 3-year service period.
