Several factors influence the performance of mule hide self-adhering modified bitumen in asphalt or bitumen modification systems. Key factors include the quality and type of polymer modifiers used, the application temperature, substrate surface preparation, and environmental conditions during installation. Additionally, the thickness of the membrane and the presence of contaminants can affect adhesion and overall durability. Proper handling and installation techniques are also critical to ensure optimal performance and longevity of the modified bitumen system.
