Viscosity garde bitumen

VG10, VG20, VG30, VG40

Viscosity Grade Bitumen (VG Bitumen) is tested differently from other types and grades of bitumen.

Bitumen Viscosity Grade VG-10, VG-20, VG-30, VG-40. Viscosity Grade Bitumen (Asphalt) is a Bitumen grade mostly used as a Paving Grade and it's suitable for road construction and for the asphalt pavements producing with premier attributes. VG Bitumen is usually used in the production of hot mix asphalt. Globally known as viscosity testing, this testing method has been introduced to the industry in order to make the behavior of bitumen predictable at various temperatures.

Viscosity Grade bitumen are specified by the methods described in ASTM Standard as AASHTO M226-80 and D3381–09 (2008). Viscosity Graded properties are mostly indicated at 60 C (140 °F).


Bitumen VG 40

Bitumen VG 40 is a Viscosity Grade Bitumen which is widely used in spraying applications such as surface-dressing and paving in a very cold climate. It is also used to manufacture bitumen emulsion and modified bitumen products.

Bitumen VG 30

Bitumen VG 30 is especially used to construct extra heavy duty Bitumen pavements that need to tolerate significant traffic loads. It can be used instead of 60/70 penetration bitumen grade.

Bitumen VG 10

VG-10 is mostly used in spraying applications such as surface dressing and Paving in very cold climate instead of 80/100 penetration bitumen grade. It is also used to produce Bitumen Emulsion and Modified Bitumen products.


The founders in the year 2012 have established the Kiapetro company with the aim of better providing and making use of Bitumen and Petroleum Products.
