Polymer Modified Bitumen (PMB) refers to a blend of traditional bitumen with polymers to enhance the performance characteristics of the asphalt. By incorporating polymers, often styrene-butadiene-styrene (SBS), ethylene-vinyl acetate (EVA), or other elastomers and plastomers, the resulting product exhibits improved elasticity, cohesion, and resistance to deformation. PMB is particularly effective in resisting ruts and cracks, which can be caused by heavy traffic or temperature extremes, making it ideal for use in road surfaces, roofing, and waterproofing applications.

The modification process with polymers not only helps in increasing the durability and lifespan of paved surfaces but also contributes to better resistance to water damage, UV radiation, and certain chemicals. Moreover, the flexibility conferred by polymer modification is advantageous during temperature fluctuations, preventing cracking in cold temperatures and softening in the heat.
