What technical requirements define what is modified bitumen roofing for asphalt or bitumen modification?
Modified bitumen roofing is defined by its use of polymer additives, such as APP (Atactic Polypropylene) or SBS (Styrene-Butadiene-Styrene), which enhance the material’s elasticity, UV resistance, and overall durability. The technical requirements include a minimum tensile strength, elongation properties, and thermal stability. Additionally, the roofing must meet specific ASTM standards for performance, including resistance to puncture and impact, as well as proper adhesion properties for installation. These modifications ensure improved longevity and performance in various weather conditions.
