Abstrakt: | The pressing demand for sustainable advancements in road infrastructure has catalyzed extensive research into environmentally conscious alternatives for the maintenance and restoration of asphalt concrete pavements. This paper offers a comprehensive review and analysis of bio-based rejuvenators as a promising avenue for enhancing the longevity and sustainability of asphalt. Through a multifaceted exploration, it delves into various aspects of this innovative approach. Providing a thorough overview of bio-based rejuvenators, the study highlights their renewable and environmentally friendly characteristics. It conducts an in-depth examination of a wide spectrum of bio-derived materials, including vegetable oils, waste-derived bio-products, and biopolymers, through a comprehensive survey. The paper evaluates how bio-based rejuvenators enhance aged asphalt binders and mixes, effectively mitigating the adverse impacts of aging. Furthermore, it investigates how these rejuvenators address environmental concerns by identifying compatibility issues, assessing long-term performance, and evaluating economic feasibility. Finally, the paper outlines potential advancements and research pathways aimed at optimizing the utilization of bio-based rejuvenators in asphalt concrete, thereby contributing to the sustainable evolution of road infrastructure.
