According to the description in the reference information, the preparation method of SBS modified bitumen is simple and does not require special equipment. Simply melt and dehydrate the bitumen, add SBS to the bitumen while stirring, or add the bitumen to SBS, and continue to heat and stir until it is homogeneous. Therefore, it can be said that the preparation method of SBS modified bitumen is simple and does not require special equipment.

 

As for whether the performance can meet the requirements of construction and road surface, the reference information mentions that SBS modified bitumen has good high-temperature fatigue resistance, impact resistance, aging resistance and excellent low temperature performance. At 0℃, its ductility can reach 100 cm, the rebound rate is 85%, the brittleness point of Fraas is less than -35℃, the penetration degree is greater than 0.7, and the heat resistance is 86℃. Therefore, the road bitumen modified by SBS can meet the requirements of different roads, and the modified construction bitumen has good performance and can meet the requirements of different bitumen felt.

 

In summary, the preparation method of SBS modified bitumen is simple and does not require special equipment, and its performance can meet the requirements of construction and pavement.
