Description

Penetration Grade Bitumen, is classified by influence trait. This grading’s basic assumption is that less viscous asphalt, deeper the needle will penetrate. Bitumen which is made during oxidation process of vacuum bottom. Bitumen production feed-stock that derives from distillation tower residue in vacuum oil refineries. At bitumen production unit in a manner that its penetration point. Penetration Grade Bitumen is commonly used in road surfacing, and some industrial applications. Additional processing yields other grades of bitumen products and their application. it is black semi solid heavy hydrocarbon which is the last product of extract tower which by cool down of ambient temperature will convert to solid. With increase of temperature the bitumen will become semi solid and then liquid. Main content of bitumen us hydrocarbon with high molecular weight contenting oil, resin and asphalten.
