What technical requirements define sbs modified bitumen for asphalt or bitumen modification?

SBS modified bitumen must meet specific technical requirements, including enhanced elasticity, improved temperature resistance, and superior adhesion properties. The polymer content typically ranges from 3% to 7%, ensuring optimal performance. The softening point should be elevated to withstand high temperatures, while the penetration grade should be appropriate for the intended application. Additionally, the modified bitumen should exhibit excellent aging resistance and low-temperature flexibility to ensure durability and longevity in various environmental conditions.
