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

Cold process modified bitumen for asphalt or bitumen modification must meet specific technical requirements, including viscosity, elasticity, and adhesion properties. The material should have a controlled softening point to ensure proper application at lower temperatures. Additionally, it must exhibit enhanced resistance to aging and temperature fluctuations. Compatibility with existing asphalt materials is crucial, along with compliance with relevant industry standards, such as ASTM or AASHTO, to ensure performance and durability in various environmental conditions.
