Aging Phenomenon in Asphalt Concrete Pavements: A Literature Review

摘要

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)
