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

The technical requirements for torch-applied modified bitumen include a minimum softening point of 100°C, a penetration grade of 60-70 dmm, and a tensile strength of at least 1.5 MPa. Additionally, the material should exhibit excellent elasticity, adhesion properties, and resistance to temperature fluctuations. The modified bitumen must also comply with relevant ASTM or AASHTO standards, ensuring durability and performance in various environmental conditions. Proper application techniques are essential for optimal bonding and longevity.
