What technical requirements define modified bitumen solvant asphalt for asphalt or bitumen modification?

Modified bitumen solvent asphalt must meet specific technical requirements, including viscosity, elasticity, and temperature susceptibility. The viscosity should allow for easy application while ensuring adequate bonding. Elasticity is crucial for flexibility and resistance to cracking. Additionally, the material should exhibit low-temperature performance to prevent brittleness and high-temperature stability to avoid softening. Compatibility with existing asphalt and environmental considerations, such as low volatile organic compounds (VOCs), are also essential for effective modification.
