Final Report
Description:

Asphalt aging is a complex process that derives from permanent compositional changes in the asphalt binder which result from its interaction with the atmosphere under prevailing environmental conditions. Hence, both constructed pavement properties and local environmental conditions determine the evolution of aging with time. The properties of asphalt binder change as it ages, leading to hardening of the asphalt pavement. These changes are believed to be a major contributor to pavement failure by cracking. Understanding the factors that drive binder aging and their impact on pavement performance, within the context of local climatic conditions and mix design methods, is important to assess current state practices and to guide the development of improved specifications for binder and aggregate selection. The broad objective of this research project is to develop an understanding of asphalt binder aging mechanisms. Isolating the most influential variables involved and analyzing the aging process within the context of geospatial conditions relevant to the State of New Mexico i.e., climate, typical materials, and construction practices.
