The reutilization of waste generated by industrial processes has become a majorenvironmental objective in scientific and technical research. In the construction sector, there is a broad range of techniques for the exploitation of different types of waste, which can then be used as a replacement for raw materials. This paper presents the results of a study of vinasse, a by-product of biomass ethanol, andanalyzes its viability as a bitumen modifier in asphalt mixes. For this purpose, four AC-16S asphalt mixes were evaluated for moisture sensitivity, plastic deformation, stiffness, and fatigue. The mix formulas were the following: (Mix 1) 50/70 bitumen; (Mix 2) 50/70 bitumen modified with 10% vinasse; (Mix 3) rubber bitumen; (Mix 4) rubber bitumen modified with 10% vinasse. The results of this study showed that bitumen modified with vinasse improved the mechanical performance of the AC-16S mix and also contributed to the valorization of vinasse waste.
