Implementation of Composite Pavement Systems

In 2014, the Federal Highway Administration (FHWA), working in collaboration with the American Association of State Highway and Transportation Officials (AASHTO), selected the Strategic Highway Research Program 2 (SHRP2) Project R21 for funding under the SHRP2 Implementation Assistance Program (IAP). The IAP is designed to help highway and transportation agencies implement and deploy technologies and solutions developed under the SHRP2 program. To accomplish this, the FHWA administered a series of activities aimed at fostering the implementation of composite pavement systems: (1) Provision of technical assistance and support to State Highway Agencies (SHAs) in the planning, design, and construction of new composite pavement systems; (2) Development of a workshop on the design and construction of new composite pavement systems and delivery of the workshop to SHAs; (3) Sponsorship of a multi-state showcase event promoting new composite pavement systems and featuring a visit to a nearby project; (4) Conduct of a multi-state peer exchange providing a forum for SHAs to share their knowledge of and experience with new composite pavement systems; and (5) Provision of technical outreach through technical presentations on new composite pavement systems at national conferences and events. This report documents the various implementation activities that were performed and captures some of the critical lessons learned that can be used by SHAs as they move forward with adopting composite pavement systems.\n
