What process parameters influence granulated modified bitumen roofing in asphalt or bitumen modification?
The key process parameters influencing granulated modified bitumen roofing include the type and ratio of modifiers (such as SBS or APP), the temperature during mixing, and the shear rate applied. Additionally, the granulation process parameters, including cooling rate and granule size, significantly affect the final product’s performance. Proper control of these parameters ensures optimal adhesion, flexibility, and durability of the roofing material, enhancing its resistance to environmental factors.
