Which factors affect gaf sbs modified bitumen in asphalt or bitumen modification systems?

Several factors influence the performance of GAF SBS modified bitumen in asphalt systems. Key factors include the type and grade of the base bitumen, the specific SBS polymer used, the modification process (temperature and mixing time), and the ratio of SBS to bitumen. Additionally, environmental conditions, such as temperature and UV exposure, as well as the intended application (e.g., roofing or paving), can significantly affect the properties and durability of the modified bitumen.
