Bitumen VG-10 (80/100) IOCL/BPCL/HPCL

About Bitumen VG-10 (80/100) IOCL/BPCL/HPCL

Bitumen VG-10 (Viscosity Grade 10), commonly equivalent to 80/100 penetration grade, is a medium-soft paving grade bitumen widely used in road construction and allied infrastructure works. Produced and supplied by leading Indian refiners like Indian Oil Corporation, Bharat Petroleum Corporation Limited, and Hindustan Petroleum Corporation Limited, it complies with IS 73:2013 standards for viscosity-graded bitumen.

This grade is particularly suitable for moderate climatic conditions and ensures a balanced combination of workability, durability, and resistance to deformation.

Key Specifications (Typical Values)

Note: Values may slightly vary depending on refinery source.

Applications

Bitumen VG-10 is widely used in:

1. Road Construction

• Surface dressing and thin bituminous layers
• Low to medium traffic roads
• Rural and urban roads in moderate climates

2. Asphalt Mixes

• Dense Bituminous Macadam (DBM)
• Bituminous Concrete (BC) for flexible pavements

3. Maintenance Works

• Patching and repair works
• Crack sealing and preventive maintenance

4. Industrial Uses

• Waterproofing applications
• Bituminous coatings and primers

Functions

Bitumen VG-10 plays several critical roles:

• Binder: Holds aggregates together in asphalt mixtures
• Waterproofing Agent: Prevents water ingress into pavement layers
• Adhesive: Provides strong bonding between aggregates
• Flexibility Provider: Allows pavement to withstand minor deformations

Benefits

• Ideal for small-scale and manual road works

2. Cost-Effective

• Economical option for low to medium traffic roads

3. Good Adhesion

• Strong bonding with aggregates ensures longer pavement life

4. Flexibility

• Reduces risk of cracking in moderate climates

5. Widely Available

• Consistent supply from major Indian refiners like
  Indian Oil Corporation,
  Bharat Petroleum Corporation Limited,
  Hindustan Petroleum Corporation Limited

6. Standard Compliance

• Manufactured as per IS 73:2013, ensuring quality and reliability

Summary

Bitumen VG-10 (80/100) is a versatile and widely used paving grade bitumen that offers a balanced mix of performance, economy, and ease of application. It is especially suited for moderate climates and low to medium traffic conditions, making it a preferred choice for government and private infrastructure projects across India.
