This publication captures the results from TRB Session 462: Relationship of Laboratory Mix Aging to Asphalt Mixture Performance, which was held during the 95th Annual Meeting of the Transportation Research Board in 2016. Numerous new or improved asphalt mixture testing and procedures are currently being evaluated to try to show relationships to mix field performance. One critical aspect of this work, that needs to be developed, is a lab aging method that will accurately reflect the mix aging in the field. This circular provides four papers on different aspects of addressing this issue. These range from handling the mix at the production facility, to varying the lab mix conditioning, toward capturing real world situations. It also includes the comparison of mix and binder properties from two field projects which shows the relationship to changes with aging of the pavement.
