The key process parameters influencing Ferrari 308 GT4 modified bitumen in asphalt modification include temperature, shear rate, and mixing time. Higher temperatures enhance the dispersion of the modifier, while optimal shear rates ensure uniform blending. Additionally, extended mixing times can improve the interaction between the bitumen and the modifier, leading to enhanced performance characteristics such as improved elasticity and resistance to deformation. Proper control of these parameters is crucial for achieving desired material properties.
