Long-Term Aging of Recycled Asphalt Binders: A ... - ResearchGate
WebIn asphalt industry, rejuvenators are either used at an initial virgin state of the binder to reduce mix ageing or blended at a later stage in recycled materials to improve the properties of aged mix. The current study focuses on evaluating the performance of asphalt mixes prepared by blending rejuvenators in already aged binders. Web26 de set. de 2024 · Bitumen samples were aged by two different conditioning methods to simulate accelerated long-term aging. A more rigorous conditioning was performed using extended pressure aging vessel (PAV) at 16, 24, 40 and 72 h, whereas a more in-service aging was performed using thin-film (100 µm) oven aging (TFOA) at 70 °C for 3,15, 28, … Web19 de mar. de 2024 · As asphalt materials are exposed to very high temperatures before construction, such as in the transportation stage or the storage stage, short-term aging of asphalt material occurs. At these stages, diffusion or blending between RAP (reclaimed asphalt pavement) binder and virgin binder may occur. In this study, recycled blends, … dutch microcar
