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.
Viscosity Grade Bitumen is petroleum grade bitumen, which produced from fractional vacuum bottom which comes from the distillation of crude oil, which feasible appliance and behavior changes according to its temperature.
Viscosity Grade bitumen is specified by ASTM Standard D3381-09 and AASHTO M226-80 (2008). VG Bitumen specifications cover by Viscosity at 60 ̊C (140 °F).
We have two methods of grading:
Viscosity grade bitumen has a thermoplastic feature which causes the material to soften at high temperatures and to harden at lower temperatures. This temperature viscosity relevance is significant when specifying the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen. In the Viscosity Grade Bitumen specifications, the most important emphasizes is based on the Bitumen ductility.
Viscosity Grade Bitumen Uses
VG-10 is mostly used in spraying applications such as surface dressing and Paving in a very cold cWe have two methods of grading:limate instead of 80/100 penetration bitumen grade. It is also used to produce Bitumen Emulsion and Modified Bitumen products.
VG-20 is used for paving in cold climate & high altitude regions.
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 a 60/70 penetration bitumen grade.
VG-40 is used in highly stressed areas such as intersections, near toll booths, and truck parking lots instead of 30/40 penetration grade. Because of higher viscosity, stiffer Bitumen mixes can be produced to amend resistance to shoving and other problems related to a higher temperatures and heavy traffic loads.
We have the capability to supply customers a wide range of Bitumen viscosity grades such as VG 10, VG 20, VG 30, VG 40.
