Bitumen (Polymer Modified Polymer)

Bitumen is a product of Crude oil Distillation. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process. As such, it is correctly known as refined bitumen. Bitumen is a low-grade of crude oil which is composed of complex, heavy hydrocarbons. Polymer modified binders (PMB) are a major advancement in bituminous binder technology as these materials better satisfy the demands of increasing traffic volumes and loads on our road networks. As well as natural rubbers, polymers such as styrene butadiene styrene (SBS), polybutadiene (PBD) and ethylene vinyl acetate (EVA) are commonly used to modify bitumen.
