What Are the Different Types of Bitumen?

Bitumen is not a single product. It is manufactured and processed into different grades and formulations to meet the requirements of various construction and industrial applications. Engineers select the appropriate type of bitumen based on pavement design, environmental conditions, traffic intensity, waterproofing needs, and industrial performance requirements.

Each type of bitumen is engineered to provide specific advantages such as higher flexibility, improved heat resistance, better workability, enhanced waterproofing, or superior durability.

Why Are There Different Types of Bitumen?

Every construction project has unique technical requirements. A highway carrying heavy commercial traffic requires a different bitumen grade than a residential road. Likewise, roofing membranes, waterproofing systems, and industrial coatings require specialized bitumen products with enhanced resistance to heat, moisture, and aging.

Using the correct type of bitumen helps improve:

• Pavement durability
• Waterproofing performance
• Traffic load resistance
• Temperature stability
• Construction efficiency
• Service life
• Maintenance costs
• Overall project performance

Main Types of Bitumen

Penetration Grade Bitumen

Penetration Grade Bitumen is the most widely used paving bitumen for road construction and asphalt production. It is classified according to its penetration value, which indicates the hardness or softness of the material under standardized laboratory testing.

Available Grades

• Bitumen 30/40
• Bitumen 40/50
• Bitumen 50/70
• Bitumen 60/70
• Bitumen 80/100

• Bitumen 100/120
• Bitumen 160/220

Common Applications

• Highways
• Expressways
• Urban roads
• Airport runways
• Asphalt plants
• Parking areas

Advantages

• Excellent adhesion
• Long pavement life
• Superior waterproofing
• Cost-effective performance
• Reliable durability

Performance Grade (PG) Bitumen

Performance Grade Bitumen is developed using the Superpave Performance Grading System and is selected according to pavement temperatures and traffic conditions.

Available Grades

• PG 52-10
• PG 52-16
• PG 52-22
• PG 58-10
• PG 58-16
• PG 58-22
• PG 64-10

Viscosity Grade (VG) Bitumen

Viscosity Grade Bitumen is classified according to its viscosity rather than penetration value, providing more consistent performance during asphalt production and pavement construction.

Available Grades

• VG-10
• VG-20
• VG-30
• VG-40

Equivalent Asphalt Grades

• AC-10
• AC-20
• AC-30

• Industrial roads
• Bridge approaches

Advantages

• Excellent workability
• Improved pavement durability
• Better resistance to heavy traffic
• Reliable temperature performance

Oxidized Bitumen

Oxidized Bitumen, also known as Blown Bitumen, is produced by blowing air through penetration-grade bitumen. This process increases its hardness, softening point, and resistance to heat and aging.

Available Grades

• Bitumen 85/25
• Bitumen 95/25
• Bitumen 115/15

Common Applications

• Roofing membranes
• Waterproofing systems
• Pipe coatings
