SBS polymer modified asphalt is applied in the bitumen modification process through a blending technique. The SBS polymer is typically added to hot asphalt at temperatures around 160-180°C, allowing for effective dispersion and interaction. This process enhances the asphalt’s elasticity, temperature resistance, and overall performance. The modified asphalt can then be used in various applications, such as road construction and maintenance, providing improved durability and resistance to cracking and deformation.
