This study explores the effect of gossypol resin — an underutilized by-product of the cottonseed oil industry — on the cohesion behavior of 60/90 penetration-grade bitumen. Modified binders were prepared with 0%, 2%, 4%, 6%, and 8% gossypol resin by weight and analyzed for penetration, softening point, ductility, cohesion force, FTIR spectra, and storage stability. Results indicate that 4% gossypol resin addition yields optimal performance, increasing cohesion force by 70% and softening point by 7°C, while maintaining acceptable ductility. FTIR analysis confirmed molecular interactions between bitumen and gossypol functional groups. The findings demonstrate that gossypol resin serves as a promising bio-based modifier, offering a sustainable and technically effective method for improving bitumen cohesion in road construction applications.
