Abstract Infrared (IR) technology was recommended as part of the SHRP2 Technologies to Enhance Quality Control on Asphalt Pavements (R06C) product. As part of that recommendation, field projects were completed to demonstrate the use and effectiveness of an IR asphalt pavement scanner for control of asphalt mixture temperature uniformity, and to confirm the short and long-term benefits of the IR technology. A total of ten field demonstration projects and eight workshops were completed. The purpose of this report is to provide a summary of the field demonstration projects and workshops. 17. Key Words 18.
