Aging Phenomenon in Asphalt Concrete Pavements: A Literature Review
The properties of the asphalt cement binder in asphalt concrete (AC) significantly affect flexible pavement performance. These properties change as a function of service time. The GA airport performance and longevity part of this study confirmed the significant contribution of asphalt aging to the loss of flexible pavement serviceability. A comprehensive literature review was conducted to consider the various factors that influence asphalt aging and techniques for alleviating the problem. Two major effects dominate asphalt cement aging: (1) loss of volatile components and oxidation in the construction phase - primarily during mixing - (short-term aging) and (2) progressive oxidation of the in place mixture in the field (long-term aging). Many efforts have been directed to better understand the aging phenomenon and laboratory simulation of field asphalt cement aging. Laboratory aging studies have primarily been conducted with asphalt cement, ignoring the effect of the aggregate on the AC aging phenomenon.
