In the production of modified bitumen, the following factors should be considered when selecting SBS modifiers:

1. Modifier structure type: SBS modifiers are divided into linear structures and star structures. Linear SBS modifiers are easier to handle in terms of processing performance, while star SBS modifiers usually have better performance. Therefore, when selecting, it is necessary to decide which structure of modifier to use based on the requirements of the production process and the capabilities of the processing equipment.

2. Performance requirements: SBS modifiers with different structures have different effects on the rheological properties, viscoelasticity, ductility and other properties of modified bitumen. Linear structures may provide better processability in some cases, while star structures may perform better in impact resistance, crack resistance and wear resistance. Therefore, it is necessary to ｓｅｌｅｃｔ a suitable modifier based on the specific usage scenario and performance requirements.

3. Properties of base bitumen: When selecting SBS modifiers, the properties of base bitumen, including its viscosity, temperature sensitivity, etc., must also be considered. Different base bitumens may interact with different types of SBS modifiers, affecting the performance of the final modified bitumen.

4. Production process: The control of temperature and time during the production process will also affect the selection of modifiers. Linear and star-shaped SBS modifiers may show different effects under different temperature and time conditions, so they need to be optimized according to the specific production process.

In summary, when selecting SBS modifiers, factors such as its structural type, performance requirements, base bitumen characteristics, and production process should be comprehensively considered to ensure that the performance of the final modified bitumen meets the engineering requirements.
