Summary Report on Aging of Asphalt-Aggregate Systems
The report contains a literature study that provides increased understanding of the aging phenomenon in asphalt-aggregate mixtures and identifies aging procedures which show promise for development as performance-related accelerated aging tests. The author considers two stages of aging: short term, which occurs during mix preparation; and long-term aging, which occurs during the subsequent life of the pavement. Extended heating procedures show the most promise for short-term aging, and pressure oxidation and/or extended heating effects of aging in mixtures include resilient modulus, indirect tensile test, and dynamic modulus test. Tests on recovered asphalt will also be necessary and microviscosity, microductility, and chemical fractional tests on the recovered asphalts will be considered.
