This thesis compares asphalt mixture properties before and after one year of field aging. Simple mixtures, one aggregate source for coarse, fine, and dust proportions, were developed and tested using four mixture tests to isolate asphalt-aggregate interaction. The results found asphalt-aggregate interaction effects and mixing temperature had considerable effects on mixture aging after 1 year. Differences in mass loss, rut depth, and indirect tensile strength that existed before aging became more pronounced after aging. This thesis’ results agree with the literature reviewed and generates new knowledge for mixture design and materials selection considerations for improved pavement performance. It is recommended that mixture conditioning be used with an appropriate mixture conditioning protocol to more accurately categorize mixture ingredients effects on aging.
