Abstract

The multiscale evaluation of asphalt composites is a method whereby material behaviors are viewed as a consequence of mechanisms that are active at different length scales within the asphalt concrete mixture. Evaluations in this line of study involve identifying the functional mechanisms at the specific length scales where they are most active. This framework may offer additional insights into key behaviors of asphalt concrete as well as provide information on the link between constituent material behaviors and bulk mixture properties. In this chapter, the multiscale study of asphaltic composites is presented, along with the implications of this method on the oxidative aging phenomenon in asphalt concrete.
