How is epdm vs modified bitumen applied in asphalt or bitumen modification processes?

EPDM (Ethylene Propylene Diene Monomer) and modified bitumen are applied differently in asphalt modification processes. EPDM is typically used as a rubber additive, blended with asphalt to enhance elasticity and durability. It is mixed at high temperatures to ensure proper dispersion. In contrast, modified bitumen involves incorporating polymers, such as SBS (Styrene-Butadiene-Styrene), directly into the bitumen during production, improving its performance characteristics. Both methods aim to enhance the lifespan and performance of asphalt in various applications.
