dc.description.abstract
The rising demand and increasing environmental concerns necessitate the urgent exploration of alternative, sustainable resources as partial or full replacement for bitumen. One of the promising approaches is the use of bio-based alternatives as bitumen substitutes. This study utilised solubility science to assess the fundamental physicochemical compatibility between bitumen and two bio-based additives. Tall oil (bio-additive-1) and waste cooking oil (bio-additive-2) were employed as bio-sourced additives. The Hansen solu-bility parameters (HSP) of bitumen, its subfractions and bio-additives were measured. Frequency sweep tests and bending beam rheometer (BBR) tests were also carried out. Bio-additive-1 showed better performance and efficiency compared to bio-additive-2 in improving the low-temperature performance and durability of bio-bitumen. The HSP of bio-additive-1 was closer to those of bitumen and its subfractions compared to bio-additive-2, which likely contributes to increased compatibility. The overlapping ratios of Hansen spheres and bitumen subfractions were positively correlated with the rheological properties of the bio-bitumen.
