Which factors affect modified bitumen underlayment in asphalt or bitumen modification systems?

Several factors influence modified bitumen underlayment in asphalt or bitumen modification systems. These include the type and percentage of polymer used for modification, the base asphalt’s properties, temperature variations during application, and the presence of additives. Additionally, environmental conditions such as UV exposure, moisture, and thermal cycling can impact the performance and durability of the modified bitumen. Proper installation techniques and substrate preparation also play crucial roles in ensuring optimal performance.
