What process parameters influence fre asphalt modified in asphalt or bitumen modification?

The process parameters that influence the modification of asphalt or bitumen with free asphalt include temperature, mixing time, shear rate, and the type and amount of modifier used. Higher temperatures can enhance the dispersion of the modifier, while optimal mixing time ensures uniformity. Shear rate affects the viscosity and homogeneity of the blend. Additionally, the choice of modifier, such as polymers or rubber, significantly impacts the performance characteristics of the modified asphalt.
