2 Long-Term Aging of Asphalt Mixtures for Performance Testing and Prediction: Phase III Results cores from in-service and test track pavements from eight states in the United States and the province of Manitoba in Canada. Although the original NCHRP Project 09-54 deliverables represent significant contributions to the study of asphalt mixture aging, several critical shortcomings have become evident.
