dc.description.abstract
Bio-based binders offer a potential solution for the availability issues of bitumen, though their aging behaviour may differ mainly due to higher oxygen content. This study aims to understand the aging resistance of model bio-based binders produced from various vegetable oils (palm, linseed, sunflower, olive) and rosin esters (Rosin A, B, C). A commercial bio-based binder was used for comparison and design. FTIR-ATR show no differences through lab aging, while DSR results reveal varying impacts after lab aging. The types of rosin esters and vegetable oils significantly affect aging resistance. Although the specific chemical characteristics of the rosin esters influencing aging remain unclear, a strong correlation exists between the iodine numbers of vegetable oils, indicating that oils with iodine numbers higher than 150 are unsuitable for bio-based binders. This paper provides useful information about bio-based binder component properties helping at developing materials that resist aging.
