Which factors affect modified bitumen torched applied in asphalt or bitumen modification systems?

Several factors influence the performance of modified bitumen when torched applied in asphalt or bitumen modification systems. Key factors include the type and quality of the polymer modifier, the application temperature, and the substrate condition. Additionally, the torching technique, including flame intensity and duration, affects adhesion and curing. Environmental conditions, such as humidity and temperature, also play a crucial role in the effectiveness of the application and the long-term durability of the modified bitumen.
