VG-20 Bitumen

Overview:

VG-20 is a medium-soft grade of bitumen suitable for areas with moderately cold climates. It provides a balance of flexibility and strength, ensuring durability under light to medium traffic.

Key Features:

  • Medium viscosity, versatile usage

  • Strong bonding with aggregates

  • Better resistance to weathering compared to VG-10

  • Provides longer service life for roads

Applications:

  • Used in hilly and moderate climate regions

  • Suitable for asphalt concrete and surface dressing

  • Works well in low to medium traffic areas

Technical Advantage:

VG-20 is a preferred choice in northern and northeastern India, where winters are cold but summers are moderate, ensuring year-round road performance.

🔎 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%).
