Bitumen 50/70 – Ideal Paving Bitumen for Temperate Climates
SEBCO’s Penetration Grade Bitumen 50/70 is a high-quality petroleum bitumen, produced through the air-blowing process from vacuum bottom residue. This semi-hard grade features a penetration value of 50–70 dmm and a softening point between 46–54°C, making it ideal for paving applications and road construction in moderate climates.
Key Features
- Excellent Adhesion to aggregates
- Low Permeability, resistant to water penetration
- Thermoplastic Behavior – softens with heat, hardens when cooled
- Dynamic Softening Temperature: 35–45°C
- Friction Coefficient: 0.4–0.6
Best Use & Climate Suitability
Bitumen 50/70 is designed for paving in temperate regions. It balances softness and hardness, making it perfect for hot mix asphalt, road repairs, and general infrastructure works. Softer grades suit colder climates; harder ones are better for hotter areas.
Applications
- Road and highway paving
- Asphalt mix production
- Construction insulation
- Waterproofing systems
Quality & Compliance
SEBCO ensures:
- Third-party inspections at loading
- Batch test reports before shipping
- Compliance with DIN EN 12591:99 (European Standard)
Packaging Options
Available in:
- Steel drums
- Jumbo bags
- Bitutainers
