- Penetration: 50-70 dmm
- Softening Point: 47-56°C
- Viscosity at 60°C: 400-700 cP
- Applications: Primarily used in hot climates for road construction, especially for highways and other heavy-duty roads.
- Characteristics: Provides a balance between viscosity and penetration, making it ideal for areas with moderate to high temperatures.
- Penetration: 60-70 dmm
- Softening Point: 49-56°C
- Viscosity at 60°C: 450-750 cP
- Applications: Commonly used for road construction, particularly for areas with temperate climates. Suitable for flexible pavements and provides good adhesion to aggregates.
- Characteristics: Offers moderate hardness with good stability under various climatic conditions.
- Penetration: 60-90 dmm
- Softening Point: 48-55°C
- Viscosity at 60°C: 600-950 cP
- Applications: Used for surface dressing, patching, and as a binder in asphalt mixes. Suitable for both urban and rural roads.
- Characteristics: Slightly softer than 60/70, making it more flexible and suitable for use in cooler climates or with different pavement structures.
- Penetration: 80-100 dmm
- Softening Point: 42-52°C
- Viscosity at 60°C: 750-1000 cP
- Applications: Ideal for colder climates and for surfaces requiring flexibility. Used in bituminous mixes and waterproofing applications.
- Characteristics: Softer bitumen, providing higher flexibility and better workability, but lower load-bearing capacity compared to harder grades.
- Penetration: 85-100 dmm
- Softening Point: 40-50°C
- Viscosity at 60°C: 800-1100 cP
- Applications: Primarily used for road construction in colder regions, waterproofing, and for surface coatings in industrial applications.
- Characteristics: The softest of the grades, offering superior flexibility and adhesive properties, ideal for areas with extreme temperatures or specific industrial uses.
