Modified bitumen membranes are applied in asphalt or bitumen modification processes by incorporating polymer additives, such as SBS (styrene-butadiene-styrene) or APP (atactic polypropylene), into the bitumen. This enhances the material’s elasticity, durability, and resistance to temperature fluctuations. The modified bitumen is then heated and applied using techniques like torching, self-adhesive methods, or hot mopping. This ensures a strong bond to the substrate, providing a waterproof and flexible roofing or paving solution.
