Abstract:
The increasing environmental concerns and depletion of petroleum-based resources have prompted the search for sustainable alternatives in construction materials. This study explores the potential of bio-based binders as eco-friendly substitutes for traditional bitumen in flexible pavement mixtures. The growing demand for sustainable infrastructure and the environmental impacts of petroleum-based products have led to increased interest in bio-based alternatives for road construction materials. This study investigates the use of bio-based binders as substitutes for traditional bitumen in flexible pavement mixtures, aiming to reduce reliance on non-renewable resources and mitigate the negative environmental effects associated with conventional asphalt production. Various bio-based binders, including vegetable oils, lignin, and animal fats, are evaluated for their compatibility with bitumen, performance under diverse climatic conditions, and potential to improve pavement durability and flexibility.Comparative analysis is conducted between bio-based and conventional bitumen, highlighting the performance benefits and challenges associated with using renewable binders. Experimental tests, including Marshall Stability, rutting resistance, and fatigue behavior, are employed to evaluate the suitability of bio-based binders in flexible pavements. The findings indicate that bio-based binders not only reduce environmental impact but also improve the lifespan of pavements by enhancing their resilience under various traffic and climatic conditions. This study underscores the potential of bio-based materials to revolutionize pavement engineering, contributing to a more sustainable and resource-efficient infrastructure.The incorporation of waste vegetable oil (WO) and algae oil (AO) significantly affects the physical and rheological properties of bitumen. The addition of these bio-based oils enhances penetration and ductility, improving flexibility and workability at optimal concentrations (8–16%). However, excessive oil content leads to reductions in viscosity, thermal stability, Marshall Stability, and tensile strength ratio, potentially compromising durability and load-bearing capacity.
