Abstract
Bitumen pavements play a critical role in modern transportation infrastructure, providing durable and reliable surfaces for roads and highways. However, traditional bitumen modifiers often rely on non-renewable resources and may contribute to environmental degradation. In response to the need for sustainable alternatives, this study explores the potential of utilizing sawdust (SD) and charcoal ash (CA) as bitumen modifiers. SD and CA were blended with bitumen grade 60/70 with 0% (control) and varied amounts of proportion using combination of SD and CA. Moreover, the sustainable modified bitumen mixture was assessed using the Marshall stability, indirect tensile strength and loss abrasion test. Specifically, adding 7SD0.5CA performs the best in stability as a sustainable modified bitumen mixture. The correlation between stability, tensile strength and loss abrasion for SD and CA modified bitumen mixture was significant, with a strong Coefficient of Determination (R2) of average 0.96 for all testing parameters. According to this study’s findings, the correlation of SD and CA content may improve the performance and engineering characteristics with respect to sustainable modified bitumen.
