The key process parameters influencing modified bitumen versus TPO (thermoplastic olefin) in asphalt modification include temperature, mixing time, and shear rate. Higher temperatures facilitate better dispersion of modifiers, while optimal mixing time ensures uniformity. Shear rate affects the degree of polymer interaction and the final properties of the modified asphalt. Additionally, the type and concentration of the modifier play crucial roles in determining the performance characteristics of the final product.
