What technical requirements define torch down modified bitumen for asphalt or bitumen modification?

Torch down modified bitumen must meet specific technical requirements, including a minimum softening point of 100°F (38°C) and a tensile strength of at least 200 psi (1.38 MPa). The material should exhibit excellent elasticity and adhesion properties, with a minimum elongation of 30%. Additionally, it must comply with ASTM D6162 standards for SBS-modified bitumen, ensuring durability and resistance to UV degradation and thermal cycling. Proper installation techniques are crucial for optimal performance.
