EPDM (Ethylene Propylene Diene Monomer) is influenced by several process parameters in asphalt modification. Key factors include the temperature during mixing, which affects the dispersion of EPDM in the bitumen, and the shear rate, which influences the polymer’s interaction with the asphalt matrix. Additionally, the duration of mixing impacts the degree of polymer integration. The ratio of EPDM to asphalt also plays a crucial role in determining the final properties of the modified asphalt.
