VG-30 Bitumen

Overview:

VG-30 is the most widely used grade of bitumen in India. It is a standard grade for road construction in areas with high traffic loads, offering excellent durability and resistance to rutting.

Key Features:

• Higher viscosity than VG-10 & VG-20

• Excellent binding and durability

• Resistant to heavy traffic pressure

• Good stability in hot climates

Applications:

• Widely used in highway and expressway construction

• Suitable for dense bituminous macadam (DBM) and bituminous concrete (BC)

• Best for heavily trafficked urban and rural roads

Technical Advantage:

VG-30 offers longer life and cost efficiency due to reduced maintenance needs, making it the most economical choice for large-scale road projects.

🔎 Quick Explanation of Terms

• Viscosity → Thickness of bitumen (flow resistance).

• Penetration → Hardness/softness of bitumen (higher = softer).

• Softening Point → Temperature at which bitumen starts to soften.

• Ductility → Ability to stretch without breaking (shows flexibility).

• Flash Point → Safety test; temperature at which bitumen gives off vapors that can ignite.

• Solubility → Purity of bitumen (should be ≥ 99%).
