Polymers are known to produce beneficial effects on asphalt mixtures, and lignin biopolymers could further improve them while contributing sustainability circularity. In this research, conventional emulsion was replaced with liquid waste containing from the wood industry in half-warm mix (HWMA) at varying substitution levels of 0% (control), 5%, 10%, 15%, 20%. Additionally, 100% reclaimed pavement (RAP) used as aggregate. The impact mixtures’ adhesion, cohesion, water resistance analyzed. Indirect tensile strength tests evaluated HWMA’s moisture damage ductility. Rolling bottle boiling were conducted assess binder-aggregate affinity. Moreover, a Life Cycle Assessment (LCA) performed compare environmental benefits HWMA those Hot Mix Asphalt (HMA). findings revealed that substituting up 15% enhances mixture’s only substitutions 5% mixtures enhanced resistance. Environmental impacts significantly reduced for all studied, Global Warming Potential (GWP) showing 33.5% reduction compared HMA.
