Polymer modified bitumen (PMB) is created by blending bitumen with polymers, enhancing its performance characteristics. The process involves heating the bitumen to a specific temperature, then adding the polymer, which can be styrene-butadiene-styrene (SBS) or ethylene-vinyl acetate (EVA). This mixture is then stirred to ensure uniform dispersion. PMB is applied in asphalt production by incorporating it into the asphalt mix, improving elasticity, resistance to deformation, and overall durability, making it suitable for high-stress applications.
