Aging affects the microstructures and mechanical behavior of asphalts. The percentage of bee structures and surfaceroughness were introduced to quantify microstructures of asphalts. The DMT modulus and adhesive force were measured to quantify the micro-mechanical properties of asphalts. A Parallel model was applied to determine asphalt composite phase mechanical response.
