Bitumen 60/70 by SEBCO: A Technical Overview
SEBCO, a leading bitumen refinery with decades of experience, specializes in the production of premium penetration-grade bitumen, including the widely used Bitumen 60/70. This grade remains the industry standard for high-performance asphalt, widely applied in road construction and infrastructure development across varying climates.
Understanding Bitumen 60/70
Bitumen 60/70 refers to a penetration grade bitumen with a penetration value between 60 and 70 (0.1 mm) under standard conditions (25°C, 100g, 5 seconds). This medium-hard grade offers the optimal balance of stiffness and elasticity, making it ideal for high-traffic roads and highways in temperate regions. SEBCO ensures this grade meets strict physical and chemical property standards for consistent field performance.
Key Specifications (Typical SEBCO Production Parameters)
- Penetration @25°C: 60–70 (0.1 mm)
- Softening Point: 48–52°C
- Ductility @25°C: >100 cm
- Flash Point: >230°C
- Solubility in Trichloroethylene: >99.5%
- Loss on Heating: <0.2%
All batches are thoroughly tested in SEBCO’s Laboratory, ensuring full compliance with ASTM D946, AASHTO M20, and equivalent international standards.
Production Process at SEBCO Refinery
SEBCO manufactures Bitumen 60/70 through direct vacuum distillation of carefully selected crude oils. This process is tightly monitored for temperature and pressure parameters to achieve precise penetration characteristics. Our advanced refining system minimizes impurities and oxidative residues, guaranteeing a homogenous product with superior performance in hot mix asphalt (HMA) applications.
Primary Applications
SEBCO’s Bitumen 60/70 is engineered for use in:
- Hot Mix Asphalt (HMA)
- Highway and airport pavements
- Resurfacing and rehabilitation projects
- Surface treatments (chip sealing)
- Tack coat and prime coat formulations
Our product is especially suited for regions with moderate temperature fluctuations and medium to heavy traffic loading.
Quality Assurance & Certification
Each SEBCO bitumen batch undergoes multi-stage QC testing, including:
Solubility
Penetration
Softening Point
Ductility
Flash Point
Thin Film Oven Test (TFOT)
We supply with full test reports, third-party certifications (upon request), and documentation required for international logistics and customs compliance.
Market Considerations
While bitumen pricing is inherently influenced by crude oil volatility, SEBCO mitigates price and supply instability through:
- Strategic crude sourcing
- Scalable production capacity
- International-grade storage and packing (bulk, drums, jumbo bags)
- Logistics integration for FOB, CFR, and CIF delivery
This positions SEBCO as a reliable supplier for global partners seeking long-term consistency in quality and delivery.
Conclusion
SEBCO’s Bitumen 60/70 stands as a benchmark in the global market for civil and highway engineering. With rigorous quality control, advanced refining technology, and customer-focused logistics, SEBCO delivers a product that meets the evolving demands of modern infrastructure projects worldwide.
