BITUMEN

Description: Bitumen is an oil based substance. It is a semi-solid hydrocarbon product produced by removing lighter fractions(such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process. Bitumen is produced in a wide range of penetration degrees, including 60/70 and 85/100.

Application: The vast majority of Bitumen is used in construction, primarily as a constituent of products used in paving and roofing applications. It is estimated that the current world consumption of Bitumen is approximately 102 million tons per year.

Approximately 85% of all the Bitumen produced is used as the binder in asphalt for roads. It is also used in other paved areas such as airport runways, car parks and footways. Further 10% of global Bitumen production is used in roofing applications, where it is waterproofing qualities are invaluable. The remaining 5% of bitumen is used mainly for sealing and insulating purposes in a variety of building materials, such as pipe coating, carpet tile backing and paint.
