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

The color of modified bitumen in asphalt is influenced by several process parameters, including the type and concentration of polymer additives, the temperature during the modification process, and the duration of mixing. Additionally, the choice of base bitumen and any fillers or pigments used can significantly affect the final color. Proper control of these parameters ensures consistent color and performance characteristics in the modified bitumen.
