Buying Iranian Export Bitumen 60/70: Specifications, Applications and Advantages
Bitumen 60/70 is one of the most popular and widely used grades of Iranian export bitumen. Due to its suitable hardness and high durability, it is extensively used in road construction, asphalt production, and waterproofing industries.
This semi-hard grade, with a penetration range of 60 to 70 (0.1 mm), provides an ideal balance between flexibility and strength, making it suitable for large-scale civil engineering and infrastructure projects.
Technical Specifications of Bitumen 60/70
Bitumen 60/70 is a thick, adhesive, water-resistant hydrocarbon material obtained from crude oil refining. Its chemical composition typically consists of approximately 87% carbon, 11% hydrogen, and 2% oxygen.
Some of its key technical properties include:
🟢 Penetration grade: 60–70 (0.1 mm) – indicating relative hardness
🟢 Softening point: 48–56°C
🟢 Density: 1.01–1.06 g/cm³
🟢 Ductility at 25°C: Minimum 100 cm
🟢 Flash point: 250°C
🟢 Loss on heating: 0.2%
🟢 Dynamic friction coefficient: 0.4–0.6
These characteristics provide good resistance to temperature variations and environmental conditions, ensuring stable long-term performance.
Main Applications
Iranian export Bitumen 60/70, thanks to its balanced hardness and flexibility, resistance to heat and cold, and strong adhesion, has a wide range of applications:
✔️ Road construction and pavement repair – asphalt production and maintenance of highways and urban roads
✔️ Waterproofing and insulation – roofs, tunnels, pipelines, and industrial tanks
✔️ Adhesives and industrial coatings – used in bituminous compounds for various industries
✔️ Bitumen felt production – thermal and sound insulation materials in buildings
Production Process of Bitumen 60/70
Bitumen 60/70 is produced from vacuum bottom, the residual product of crude oil refining in vacuum distillation towers. Through air blowing and the formation of cross-linking bonds between molecules, this material is converted into bitumen with a specific hardness and penetration grade.
The final penetration grade depends on several factors, including crude oil type, refining method, and the degree of oxidation of the vacuum bottom.
Main production equipment includes:
🟣 Distillation tower for hydrocarbon separation
🟣 Air blowing furnace for oxidation and property enhancement
🟣 Storage tanks for maintaining the product under controlled conditions
Advantages and Limitations
✅ Suitable for use in warm climates and large infrastructure projects
✅ High resistance to heat, cold, and sunlight
✅ Adequate flexibility to reduce cracking and rutting
⚠️ In very cold regions, this grade may become stiffer and more prone to cracking. For cold-climate projects, blending with softer grades may be required.
Pricing and Influencing Factors
The price of export Bitumen 60/70 is influenced by multiple factors:
🟢 Global crude oil prices
🟢 Exchange rate fluctuations and domestic economic conditions
🟢 Domestic and international market supply and demand
🟢 Transportation and insurance costs
