Owens Corning modified bitumen is applied through a process that typically involves heating the material to a specific temperature to enhance its workability. It is then applied using a torch or hot asphalt application methods, ensuring proper adhesion to the substrate. The modified bitumen can also be blended with traditional asphalt to improve performance characteristics, such as flexibility, durability, and resistance to environmental factors. This application process enhances the overall longevity and effectiveness of asphalt surfaces.
