What technical requirements define app modified bitumen membrane for asphalt or bitumen modification?

The technical requirements for app modified bitumen membranes include a minimum softening point of 100°C, a tensile strength of at least 1.5 MPa, and an elongation of 30% at break. The membrane should exhibit excellent adhesion to substrates, resistance to UV radiation, and low-temperature flexibility. Additionally, it must comply with relevant standards such as ASTM D 1970 and EN 13707, ensuring durability and performance in various environmental conditions.
