Bitumen VG-10 & VG-30 Grades in India

We at SJ EXIM play an important role in providing assured procurement and supply services as an integrated solution for Bitumen VG-10 & VG-30 grades in India. When we say integrated we actually mean integrated as we are also into the logistics services supplies through Rail, Sea and Air modes. So you don’t have to take the pain to move your Bulk Bitumen from and to any point in India.

What are the constituents of Bitumen?

Ans: The bitumen constituents are broadly classified as Asphaltenes, Resins, Naphthene Aromatics and Saturates. Ø

Asphaltenes: are dark brown friable solids, they have high polar complex aromatic material with molecular weight 1000-100000 and interact or associate more active. These are the active constituents of bitumen and these are mainly responsible for viscosity of bitumen, stiffness of bitumen and other engineering properties of bitumen. Higher Asphaltenes content results in increases softening point, viscosity with low penetration. Ø

Resins: are a dark semi-solid to solid material which is fluid when heated and brittle when cold. The resins are polar aromatics which keep asphaltenes dispersed and impart adhesiveness to bitumen. The resins with molecular weight of 500-50000. The resins are oxidized by various processes they get transformed into asphaltenes. Blown Bitumen has more percentage of asphaltenes compared to the original bitumen. Ø

Naphthene Aromatics: act as dispersion medium for peptized asphaltenes. The average molecular weight is 300-2000. The Aromatics reduce shear susceptibility.

Saturates: is Non–polar viscous oils, waxy & non waxy in nature and colorless liquid and which actually is a medium in which the asphaltenes and resins are in a colloidal state. These oils yield asphaltenes or resins on oxidation. Depending upon how much oxidization takes place, oils can get converted into resins or in turn it can get converted into asphaltenes and accordingly the properties will change. Bitumen is considered to be a colloidal system consisting of Asphaltenes, resins, Aromatics and Saturates.

Usage: Where is VG 10 & VG 30 suitable & used

a) VG 10 (Approx. penetration grade bitumen 80/100): This is the softest of all grades available in India. This is suitable for low volume roads. It is widely used in spraying applications such as surface-dressing and paving in very cold climate. It is also used to manufacture Bitumen Emulsion and Modified Bitumen products.

b) VG 30 (Approx. penetration grade bitumen 60/70): This grade is harder than VG 10 and can withstand higher traffic load. It is presently used mainly in construction of National Highways & State Highways. Also VG 30 can be used in high temperature zones as it has good thermal susceptibility
