bitumen composition

The composition of bitumen 60/70 typically includes the following components:


It is the primary constituent of bitumen 60/70, accounting for the majority of its composition. Bitumen is a highly viscous, black or dark brown material obtained from crude oil through the refining process. It consists mainly of hydrocarbon compounds and may contain small amounts of impurities.


Bitumen primarily consists of hydrocarbon compounds, including various types of aliphatic and aromatic hydrocarbons. These hydrocarbons provide the characteristic properties of bitumen, such as its viscosity and adhesion.

Asphaltene in bitumen composition

Asphaltene are a complex mixture of high molecular weight compounds present in bitumen. They contribute to the strength and durability of the asphalt produced using bitumen 60/70.


Maltenes are the fraction of bitumen that remains after removing the asphaltene. They consist of smaller molecular weight hydrocarbons and are responsible for the flow and workability of bitumen.

Resins is in bitumen composition

Bitumen also contains resins, which are a mixture of high molecular weight compounds. Resins contribute to the adhesion and cohesion properties of bitumen.

Trace Elements

Bitumen 60/70 may contain trace amounts of sulfur, nitrogen, oxygen, and metals. These elements can come from the original crude oil source or be introduced during the refining process.
