🛣️ Bitumen 60/70 – Properties, Applications, Comparison with Bitumen 40/50, and Market Analysis in Dubai 🌍
1. Introduction 📝
Bitumen, also known as asphalt in some regions 🛢️, is a viscous, black, sticky material derived from crude oil during the refining process 🏭. It plays a critical role in road construction 🛣️, waterproofing 🌧️, and industrial applications ⚙️ due to its excellent adhesive and waterproofing properties. Among the various penetration grades of bitumen, Bitumen 60/70 is one of the most widely used grades globally 🌐, particularly in road paving projects 🚧. This article provides a comprehensive technical overview of Bitumen 60/70, compares it with Bitumen 40/50, and analyzes its market dynamics and sales practices in Dubai, UAE 🇦🇪.
2. What is 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 testing conditions (ASTM D5 or IP 49) 📏. The penetration test measures the depth to which a standard needle penetrates the bitumen sample under specific conditions of temperature (25°C), load (100g), and time (5 seconds) ⏱️. This grade indicates a medium-hard bitumen suitable for moderate climatic conditions ☀️❄️.
Key Properties of Bitumen 60/70: ✅
- Penetration (25°C, 100g, 5s): 60–70 dmm 📊
- Softening Point (Ring & Ball): 49–56°C 🔥
- Ductility (5°C, 5 cm/min): ≥100 cm 🧵
- Flash Point (Cleveland Open Cup): ≥250°C ⚠️
- Solubility in Trichloroethylene: ≥99.5% 💧
- Kinematic Viscosity (135°C): ~350–500 cSt 🌀
- Density (25°C): ~1.02–1.05 g/cm³ ⚖️
3. Applications of Bitumen 60/70 🏗️
Bitumen 60/70 is primarily used in:
- Road Construction 🛣️: Ideal for base and surface courses in flexible pavements in regions with moderate temperatures.
- Asphalt Concrete Mixes 🧱: Used in hot mix asphalt (HMA) for highways, city roads, and airport runways ✈️.
- Prime and Tack Coats 🖌️: Applied between layers to enhance bonding.
- Waterproofing 🌧️: In roofing membranes and underground structures 🏢.
- Industrial Applications ⚙️: As a binder in sealants and coatings.
Due to its balanced stiffness and flexibility, Bitumen 60/70 performs well in areas where summer temperatures do not exceed 45°C and winter temperatures remain above freezing ❄️➡️☀️.
4. Comparison Between Bitumen 60/70 and Bitumen 40/50 🆚
The primary difference between these two grades lies in their hardness and temperature susceptibility. Bitumen 40/50 is harder and more suitable for hotter climates, while 60/70 is slightly softer and better for moderate conditions.
| Property | Bitumen 60/70 🟨 | Bitumen 40/50 🟥 |
|---|---|---|
| Penetration (0.1 mm) | 60–70 📏 | 40–50 📏 |
| Softening Point (°C) | 49–56 🔥 | 55–60 🔥 |
| Ductility at 5°C (cm) | ≥100 🧵 | ≥75 🧵 |
| Flash Point (°C) | ≥250 ⚠️ | ≥250 ⚠️ |
| Kinematic Viscosity (135°C) | 350–500 cSt 🌀 | 500–700 cSt 🌀 |
| Temperature Suitability | Moderate climates (up to 40°C) ☀️❄️ | Hot climates (up to 45–50°C) ☀️☀️☀️ |
| Stiffness | Medium 🟨 | High 🟥 |
| Crack Resistance | Better at low temperatures ❄️ | Lower at low temperatures ❌ |
| Rutting Resistance | Moderate 🟨 | High 🟥 |
| Common Applications | Urban roads, moderate highways 🏙️ | High-traffic highways, hot zones 🚛🔥 |
Summary of Comparison: 📌
- Bitumen 40/50 is harder and more resistant to deformation (rutting) under high temperatures 🚛🔥, making it suitable for high-traffic roads in hot regions.
- Bitumen 60/70 offers better flexibility and crack resistance in cooler conditions ❄️ and is preferred where thermal cracking is a concern.
- The choice between the two depends on climatic conditions 🌡️, traffic load 🚗, and pavement design 🛣️.
5. Production and Specifications 🏭
Bitumen 60/70 is produced through the vacuum distillation of crude oil 🛢️➡️. After atmospheric distillation removes lighter fractions (naphtha, diesel, etc.), the residue undergoes vacuum distillation to yield bitumen. Additives may be introduced to modify properties (e.g., polymer-modified bitumen 🧪), but 60/70 is typically unmodified.
International Standards: 📜
- ASTM D946 – Standard Specification for Penetration Grade Bitumen 🌐
- EN 12591 – European standard for bitumen binders 🇪🇺
- GOST 22245-90 – Russian standard (common in CIS exports) 🇷🇺
- IS 73:2013 – Indian Standard 🇮🇳
Dubai and the UAE generally follow ASTM and EN standards, with increasing alignment with GSO (GCC Standardization Organization) norms 🇦🇪✅.
6. Bitumen Market in Dubai, UAE 🇦🇪📈

Is there a dedicated bitumen refinery in Dubai?
In the United Arab Emirates, and specifically Dubai, there are many oil refineries, but you won’t find a refinery devoted exclusively to bitumen like those in Iran or India. Instead, Dubai functions mainly as:
- An importer and regional distribution hub for bitumen (especially from Iran, India, and Bahrain).
- A storage and re-export center, with bitumen held in terminals in Jebel Ali, Sharjah, and Fujairah and then dispatched to local and regional projects.
✅ SEBCO (Sebco Petroleum Group) is one of the prominent bitumen suppliers operating in the UAE, with its head office based in Dubai. The company provides high-quality penetration-grade bitumen (including 60/70 and 40/50) in drums, jumbo bags, and bulk, serving both local projects and re-export markets in the Middle East, Africa, and Asia.
Refineries in the UAE that produce bitumen as a byproduct
While there’s no stand-alone bitumen refinery in Dubai, some UAE refineries—primarily located in Abu Dhabi or Sharjah—do produce bitumen as a byproduct of crude oil refining:
- ADNOC Refining (Abu Dhabi): The Ruwais Refinery produces a range of outputs including bitumen.
- ENOC Jebel Ali Refinery (Dubai): Focuses on light products like LPG and jet fuel, with no major bitumen output.
- Gulf Petrochem (GP) (Sharjah): Involved in downstream and bitumen production.
New Bitumen Plant Development
In 2024, Petrozo Energy (Singapore) launched the construction of a $32.7 million integrated bitumen plant in Sharjah’s Hamriyah Free Zone, including:
- A production unit
- 5,000-ton storage tanks
- Drum and bitutainer filling stations
- Monthly capacity of ~6,000 MT
This marks a step toward growing local production capacity in the UAE.
Summary Table
| Location | Bitumen Refinery Presence | Notes |
|---|---|---|
| Dubai | ❌ No dedicated bitumen refinery | Acts as import/export hub. SEBCO is headquartered here. |
| Abu Dhabi (Ruwais) | ✅ Yes (byproduct in large refinery) | Bitumen part of ADNOC’s wide portfolio. |
| Sharjah | ✅ Yes | Gulf Petrochem active. New Petrozo plant under way. |
Conclusion
- Dubai does not have a dedicated bitumen refinery, but it plays a critical role as a regional hub.
- SEBCO, headquartered in Dubai, is a leading supplier of premium-grade bitumen to various export markets.
- Bitumen production in the UAE occurs mainly as a byproduct of broader refining operations, but new dedicated capacity is now being developed.
