SBS modified bitumen membranes are applied in asphalt or bitumen modification processes through a blending technique. The SBS polymer is mixed with bitumen at elevated temperatures, enhancing the material’s elasticity, durability, and resistance to temperature fluctuations. This modified bitumen can then be used in various applications, such as roofing and paving. The application process typically involves heating the modified bitumen for optimal flow, followed by spreading it onto the substrate to form a seamless, waterproof layer.
