This project has investigated the effectiveness of a Portable Infrared Spectrometer (PIRS) device in estimating percent of Reclaimed Asphalt Pavement (RAP) and its contribution into oxidative aging of a new asphalt mixture immediately after production. Based on the findings from a limited demonstration study, the research team has developed a draft field procedure and implementation plan for Idaho Transportation Department (ITD) to incorporate PIRS testing of RAP into QC/QA of asphalt pavement construction. The team has also provided recommendations for validation and pilot implementation of the PIRS procedure on future paving projects. Lastly, the team has suggested incorporating the PIRS test into the pavement management program to monitor rate of deterioration and determine optimal timing for preservation treatments of asphalt pavements.
