Aging of Bituminous Binders and Mixtures - Part II

Learn about the aging process of bituminous binders and mixtures in this comprehensive 31-minute video lecture. Explore short-term and long-term aging effects, including changes in stiffness and chemical composition. Discover the formation of various compounds during aging, such as asphaltenes, polar aromatics, and sulfoxides. Examine standardized testing methods like the Rolling Thin Film Oven (RTFO) and Pressure Aging Vessel (PAV). Investigate the influence of temperature and oxygen availability on aging. Gain insights into the elemental composition, Corbett fractions, molecular weight changes, and the relationship between oxidation compounds and viscosity in bituminous materials.
