Abstract

The widespread use of traditional bitumen, derived from finite crude oil resources, has led to growing concerns over its environmental impact, long-term availability, and cost. These challenges underscore the urgent need for sustainable, alternative binders in infrastructure applications such as road construction. Although previous research has explored bio-based and recycled waste materials as potential substitutes, these alternatives often fail to meet compatibility, durability, and performance standards.

To overcome these obstacles, this study employs a multifaceted methodology encompassing rheological, chemical, and mechanical analyses, along with environmental assessments. The objective is to develop an alternative binder synthesized from bio-based and waste materials that offers comparable or improved durability and performance. Our findings suggest that the alternative binder presents a viable replacement for traditional, petroleum-based bitumen. This innovation not only enhances the sustainability and circularity of road materials but also mitigates the construction industry's dependence on non-renewable oil resources.
