What technical requirements define cold applied modified bitumen for asphalt or bitumen modification?

Cold applied modified bitumen must meet specific technical requirements, including a minimum softening point of 70°C, a penetration grade of 40-60 dmm, and a viscosity of 2000-4000 mPa·s at 135°C. Additionally, it should exhibit excellent adhesion properties, flexibility at low temperatures, and resistance to aging and UV degradation. The modified bitumen should also comply with relevant standards such as ASTM D 6164 or EN 14023 to ensure performance and durability in various applications.
