Polymer-Modified Bitumen is bitumen enhanced with polymers to improve its performance characteristics, such as elasticity, resistance to deformation, and durability.

 

- Types:

  - SBS (Styrene-Butadiene-Styrene): Provides enhanced flexibility and resistance to rutting, ideal for high-stress pavements.

  - APP (Atactic Polypropylene): Improves temperature resistance, used in areas with extreme weather conditions.

  - EVA (Ethylene Vinyl Acetate): Offers a balance between stiffness and flexibility, suitable for various applications.

- Benefits: PMB is ideal for heavy traffic roads, bridges, and airports, where enhanced performance is required. It provides superior resistance to cracking, rutting, and aging compared to conventional bitumen.
