The key process parameters influencing SBS bitumen modification include temperature, shear rate, and mixing time. Higher temperatures enhance the solubility of SBS in bitumen, while optimal shear rates ensure uniform dispersion of the polymer. Additionally, extended mixing times can improve the interaction between SBS and bitumen, leading to better performance characteristics. Proper control of these parameters is crucial for achieving desired viscosity, elasticity, and overall durability of the modified asphalt.
