What technical requirements define flintlastic modified bitumen for asphalt or bitumen modification?

Flintlastic modified bitumen must meet specific technical requirements, including a minimum tensile strength of 200 psi, elongation of at least 20%, and a softening point between 200°F and 250°F. Additionally, it should exhibit excellent adhesion properties, low-temperature flexibility, and resistance to UV degradation. The material typically incorporates SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) modifiers to enhance performance characteristics, ensuring durability and longevity in roofing and waterproofing applications.
