🛢️ Bitumen 60/70
Medium-Hard Paving Grade Bitumen for Construction & Industrial Use
Bitumen Penetration Grade 60/70 is a widely used standard paving grade bitumen produced from the refining of crude oil. It is characterized by its penetration value (60–70 dmm at 25°C), which indicates a balanced consistency suitable for various construction and industrial applications.
This grade is commonly used in regions with moderate climate conditions, offering a reliable combination of strength, flexibility, and durability.
⚙️ Key Characteristics
- Medium hardness with stable performance
- Strong adhesion with aggregates
- مقاوم temperature variation performance
- High durability under load and traffic
- Water-resistant and sealing capability
