Several factors influence the performance of modified bitumen compared to EPDM in asphalt modification systems. These include compatibility with the base bitumen, temperature susceptibility, aging resistance, and elasticity. Modified bitumen typically offers improved adhesion and flexibility, while EPDM provides excellent weather resistance and durability. Additionally, the cost and ease of application can vary, impacting the choice based on project requirements and environmental conditions. Ultimately, the selection depends on specific performance needs and application scenarios.
