Bitumen blending is performed by carefully mixing base bitumen with modifiers or additives to achieve desired properties. The process involves heating the bitumen to a workable temperature and then adding modifiers such as polymers, crumb rubber, or other agents. The blending must ensure uniform dispersion of additives, often using high-shear mixers, to optimize performance characteristics like viscosity, elasticity, and temperature susceptibility for specific applications.
