What is Bitumen?

Bitumen is viscous, nonvolatile liquid or solid. Bitumen is a complex colloid system the chemical properties of which are dependent on the properties of crude oil from which it is produced. Pure bitumen is a colloid dispersion of microscopic asphalt particles (dispersion phase). The chemical composition...

Production Process

Bitumen is produced by fractional distillation of crude oil. Usually, distillation is done in two steps. First the crude oil is heated up to 300-350°C and introduced into an atmospheric distillation column. Lighter fractions like naphtha, kerosene and gas oil are separated from the crude oil at different...

Application and properties of Bitumen

Bitumen is an essential component of any pavement and is used widely throughout the world. Almost ninety percent of bitumen is used in road construction. The main use of bitumen in the world is in the construction of roads, from motorways to private access roads, but bitumen is also...

Penetration Grade

Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it's very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.

Cut-back bitumen

Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.

Viscosity Grade Bitumen

Bitumen are also graded and specified by their viscosity at a standard temperature (typically 60°C). Specifications for viscosity graded bitumen normally give the nominal viscosity prefixed by a V, e.g. V1500.
