Learn about the aging processes of bituminous binders and mixtures in this 37-minute video lecture. Explore short-term and long-term aging effects, and how they impact the stiffness of materials. Delve into the chemical components of bitumen, including asphaltenes, polar aromatics, aromatics, and saturates. Understand the formation of ketones and sulfoxides during aging. Discover standardized testing methods such as the Rolling Thin Film Oven (RTFO) test (ASTM D2872-19, 2019) and the Pressure Aging Vessel (PAV) test (ASTM D6521-19, 2019) used to simulate and evaluate aging in bituminous materials.
