The key process parameters influencing self-adhering modified bitumen include temperature, shear rate, and mixing time. Temperature affects the viscosity and flow characteristics, ensuring proper dispersion of modifiers. Shear rate influences the uniformity of the blend, while mixing time ensures adequate interaction between the bitumen and modifiers. Additionally, the type and concentration of modifiers, as well as the curing conditions, play crucial roles in achieving optimal adhesion and performance in asphalt applications.
