The technical requirements for SBS (Styrene-Butadiene-Styrene) modification of asphalt or bitumen include the following: a minimum SBS content of 3-5% by weight of the binder, compatibility with the base asphalt, and a specific processing temperature range (typically 180-200°C) to ensure proper blending. Additionally, the modified asphalt should meet performance criteria such as improved elasticity, temperature susceptibility, and resistance to aging and deformation, as defined by relevant standards like AASHTO or ASTM.
