Modified bitumen manufacturers apply polymer or rubber additives to traditional bitumen to enhance its performance characteristics. This process typically involves blending the base bitumen with modifiers such as SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) to improve elasticity, temperature resistance, and durability. The modified bitumen is then used in asphalt mixtures, providing superior adhesion, flexibility, and resistance to cracking and deformation, ultimately extending the lifespan of pavements and reducing maintenance costs.
