SEBCO AH70 Bitumen – Premium Asphalt for Lasting Road Performance
Reliable Performance for Demanding Infrastructure Projects
Overview
SEBCO’s AH70 Bitumen (also known as 70A) is a high-quality petroleum asphalt, engineered for superior road construction and infrastructure projects in moderate climate zones. Derived through the vacuum distillation of selected crude oils, this penetration-grade bitumen (60–70 dmm) offers excellent binding, waterproofing, and adhesive properties. Its controlled air-blown process ensures consistent quality and performance across all applications.
Engineered for Durability
AH70 is ideal for use in hot mix asphalt and plant-mix applications, where its stable softening characteristics enhance workability and performance. It maintains structural integrity under varying traffic loads and environmental conditions, making it suitable for highways, airports, parking areas, and residential roads. The gradual softening point ensures flexibility and resistance to cracking, contributing to the longevity of paved surfaces.
Common Applications
- Highway and Expressway Construction
- Urban Street Paving and Maintenance
- Airport Runway and Taxiway Surfacing
- Driveway and Parking Lot Development
- Asphalt Mix Plants and Liquid Bitumen Production
- Waterproofing in Construction Projects

Understanding the Difference Between Bitumen AH70 and 60/70
Bitumen AH70 and Bitumen 60/70 are two common bitumen grades widely used in road construction. While both serve as vital binders, they possess distinct properties that make them suitable for different applications.
Key Differences: AH70 vs 60/70 Bitumen
- Penetration Grade: AH70 is softer and more flexible compared to 60/70.
- Viscosity: AH70 has greater resistance to flow.
- Temperature Use: AH70 is preferred in hotter climates; 60/70 in moderate zones.
- Cost: AH70 is typically more expensive due to enhanced properties.
Selecting the Right Bitumen Grade for Your Project
- Temperature Conditions: Choose AH70 for high-heat environments.
- Traffic Load: AH70 is better for heavy traffic roads.
- Budget: 60/70 offers better cost-efficiency for standard use.
- Performance Requirements: Consider long-term resistance to fatigue, cracking, and rutting.
Comparison Table
| Feature | Bitumen AH70 | Bitumen 60/70 |
|---|---|---|
| Penetration Grade | Higher (softer, more pliable) | Lower (harder) |
| Viscosity | Greater (higher resistance to flow) | Lower (less resistance to flow) |
| Temperature Use | High-temperature areas | Moderate temperatures |
| Traffic Suitability | Better for heavy traffic | Light to moderate traffic |
| Cost | More expensive | Less expensive |
Conclusion
The decision between Bitumen AH70 and Bitumen 60/70 should be based on a thorough assessment of your road construction project's unique demands and priorities. Consulting with a reputable bitumen supplier or experienced road construction expert is highly recommended to ensure you select the most appropriate bitumen grade for optimal and long-lasting results.
