The technical requirements for app modified bitumen include specific performance characteristics such as improved elasticity, temperature susceptibility, and resistance to aging and deformation. Key parameters include the softening point, penetration grade, and viscosity. Additionally, the modified bitumen should meet standards for adhesion, durability, and compatibility with aggregates. Testing methods like Dynamic Shear Rheometer (DSR) and Bending Beam Rheometer (BBR) are essential to ensure the material meets the necessary specifications for asphalt applications.
