Chemical modification enhances bitumen characteristics by altering its molecular structure through the addition of reactive agents. This process improves properties such as adhesion, elasticity, temperature susceptibility, and resistance to aging. Chemical modifiers like sulfur, polyphosphoric acid, and reactive polymers form chemical bonds with bitumen components, leading to enhanced performance.
