Bitumen modifiers must meet several technical requirements for effective asphalt modification. These include compatibility with base bitumen, ensuring no phase separation occurs. The modifier should enhance properties such as elasticity, viscosity, and temperature susceptibility. Additionally, it must improve resistance to aging, UV degradation, and moisture damage. The modifier should also comply with relevant industry standards, such as ASTM or AASHTO, to ensure performance consistency and durability in various environmental conditions.
