Common Asphalt Building Block: Bitumen 60/70
Bitumen 60/70 is a type of asphalt widely used in road construction. It’s known for its versatility and good performance in pavements. This specific grade is neither too soft nor too hard, making it ideal for various road applications.
Obtaining Bitumen 60/70
There are two main ways to produce Bitumen 60/70:
- Distillation Process: This method involves refining crude oil to separate out the bitumen component.
- Vacuum Residue: Here, the leftover material after vacuum distillation is used as the base for bitumen production.
Key Properties
The “60/70” refers to the bitumen’s consistency measured by a penetration test. This grade falls within a specific range, ensuring optimal qualities for road building.
Common Uses
Bitumen 60/70 is a crucial ingredient in hot mix asphalt, used for both the foundation (base) and surface layers (wearing courses) of roads.

Bitumen 80/100: The Foundation of Strong Roads
Bitumen 80/100 is a key building block for road construction. It’s created during a refining process where leftover material from crude oil distillation undergoes further processing. This process, called “blowing,” adjusts the material’s consistency, resulting in a specific penetration range (80 to 100 points).
A Versatile Material for Lasting Performance
Bitumen 80/100 is a highly versatile material due to its unique properties. It acts like a thermoplastic, softening in hot weather and hardening in cold weather. This temperature sensitivity allows it to function effectively in various climates and applications:
- Road Construction: This grade of bitumen is a primary component in hot mix asphalt, used for both the base and surface layers (wearing courses) of roads.
- Adaptable Foundation: Bitumen 80/100 serves as the base material for many other bitumen products, making it a crucial element in road construction.
Dounia Exports: Committed to Quality
Dounia Exports prioritizes consistent quality. Their Bitumen 80/100 is produced using a fully automated “Biturox Blowing Unit” ensuring a uniform and reliable finished product.
Strong and Durable Roads: Bitumen 20/30
Bitumen 20/30 is a high-quality asphalt material ideal for road construction and repairs. It creates pavements with superior strength and durability. This type of bitumen is used to make hot mix asphalt, which forms the base and surface layers (wearing courses) of roads.
Ensuring Quality: From Production to Delivery
Dounia Exports prioritizes the quality of their bitumen 20/30. To guarantee it meets international standards, they use a multi-step process:
- Independent Inspection: International inspectors verify the quality and quantity of the bitumen during loading onto ships.
- Strict Quality Control: Throughout production, each batch is rigorously tested by Dounia's quality control team.
- Meeting Standards: Dounia Exports ensures their bitumen complies with both ASTM and European Standard DIN EN 12591:99.
This emphasis on quality control ensures you receive a reliable and long-lasting bitumen product for your road construction needs.
