This research was conducted as part of the Strategic Highway Research Program (SHRP)
A-003A contract at Oregon State University to validate the findings of SHRP contracts
A-002A and A-003B with regard to aging of asphalt-aggregate mixtures. One short-term
and four long-term aging methods were used to simulate aging of asphalt-aggregate mixes
in the field. Four aggregates and eight asphalts for a total of 32 different material
combinations were tested using different aging methods. Results of the aging studies are
compared with the A-002A and A-003B studies of asphalt binder or asphalt mixed with
fine aggregate. This research concludes that aging of asphalt mixes cannot be predicted
by tests on asphalt binder alone since results show that aggregates have considerable
influence on aging. / Graduation date: 1995
