Bitumen 60/70 Dubai UAE: Properties, Uses, and Applications
Introduction to Bitumen 60/70
Bitumen 60/70 is more than just a black, sticky substance—it’s the heartbeat of modern infrastructure, especially in regions like Dubai and across the UAE. If you’ve ever driven on the smooth highways of the Emirates or admired the sleek roofing of its skyline, chances are Bitumen 60/70 played a role. But what exactly is this material, and why is it so popular in Dubai’s booming construction scene?
What is Bitumen 60/70?
Bitumen 60/70 is a penetration grade bitumen widely used in road construction, waterproofing, and insulation. The “60/70” refers to its penetration range—meaning how deep a standard needle can penetrate the bitumen sample under specific conditions. This measurement gives insight into the hardness or softness of the material.
Why It’s Popular in Dubai, UAE
Dubai’s extreme heat demands materials that can withstand high temperatures without deforming. Bitumen 60/70 hits the sweet spot—offering enough flexibility to cope with thermal expansion while remaining durable under heavy traffic. It’s also locally available, cost-effective, and supported by strong logistical infrastructure, making it the go-to choice.
Physical and Chemical Properties
Penetration Grade Explained
The penetration test determines the consistency of bitumen. For grade 60/70, the needle penetrates between 6 to 7 mm into the bitumen under standard conditions. This mid-range grade balances hardness and plasticity—ideal for the UAE’s climate.
What Does 60/70 Mean?
Simply put, it refers to a penetration depth of 60 to 70 tenths of a millimeter. Lower values mean harder bitumen, while higher values indicate softer bitumen. For Dubai, the 60/70 grade works well due to its moderate viscosity and resilience.
Softening Point and Viscosity
Bitumen 60/70 has a softening point of about 49–56°C, meaning it maintains structural integrity under heat. Its viscosity ensures that it doesn’t flow like a liquid but remains pliable enough for easy application.
Durability and Aging Resistance
UAE’s hot climate accelerates the aging process of construction materials. Bitumen 60/70 has excellent oxidative stability, ensuring long-term performance with minimal cracking or degradation.
Manufacturing and Refining Process
Origin of Raw Materials
Bitumen is derived from crude oil through fractional distillation. The heavier fractions are further processed into bitumen. UAE sources its raw materials locally and via imports from oil-rich countries like Iran and Saudi Arabia.
Refining Techniques Used in UAE
The bitumen is refined using air blowing, vacuum distillation, and solvent de-asphalting. These ensure purity and control over penetration and softening points.
Quality Control Measures
Quality checks in UAE refineries include:
- Penetration testing
- Ductility
- Softening point
- Flash point
These tests ensure compliance with ASTM and AASHTO standards.
Applications in Construction
Road Paving and Asphalt Mixes
Bitumen 60/70 is ideal for high-traffic roads and highways. Its thermal resistance helps prevent rutting and cracking, even under constant exposure to Dubai’s blazing sun.
Climate Suitability in UAE
Dubai’s roads face surface temperatures exceeding 70°C. Bitumen 60/70 remains stable in this heat, making it an ideal choice for lasting road infrastructure.
Waterproofing in Buildings
Used in basement waterproofing, tank linings, and foundation protection, this grade is favored due to its impermeability to water and moisture.
Use in Roofing Felts
Bitumen sheets reinforced with polymers or jute are used in flat roofs across the UAE. These provide heat insulation and protect buildings from the elements.
Advantages of Bitumen 60/70
Cost Efficiency
Compared to polymers or imported specialty binders, Bitumen 60/70 offers an economical solution for both public and private infrastructure projects.
High Temperature Performance
Its ability to resist deformation and flow under high temperatures makes it a reliable choice in arid regions.
Compatibility with Additives
Bitumen 60/70 mixes well with polymers, anti-stripping agents, and crumb rubber, making it versatile for various construction needs.
Market Insights for Dubai and UAE
Demand Trends
With massive ongoing infrastructure projects like Dubai Urban Tech District and Expo City, demand for quality bitumen is skyrocketing.
Export and Import Status
While the UAE produces its own bitumen, it also imports from countries like Iran, India, and Bahrain to meet rising demand.
Key Suppliers in the Region
Leading suppliers include:

Storage and Transportation
Packaging Standards
Bitumen 60/70 is commonly packed in:
- New steel drums (180 kg)
- Polybags
- Bulk tankers for large projects
Safety Guidelines for Transport
Bitumen must be transported at temperatures above 110°C. It requires specialized tankers and trained personnel due to its flammability.
Shelf Life and Handling
Stored correctly in sealed drums, Bitumen 60/70 has a shelf life of over 12 months. Avoid moisture contact and exposure to sunlight for long-term quality.
Environmental Considerations
Sustainability of Bitumen
Bitumen is recyclable. Used asphalt can be reheated and reused, reducing environmental impact.
Emission Levels During Use
While emissions during production exist, newer methods like warm mix asphalt and additives reduce harmful fumes.
Recycling and Reusability
