Premium Bitumen 85/100 – Reliable Road Power by ATDM

ATDM is a trusted global supplier of Bitumen 85/100, offering premium-grade asphalt binders used in road construction, waterproofing, and industrial applications. This grade is softer than 60/70 and 80/100, making it perfect for regions that experience cold or moderate weather. Engineers, contractors, and asphalt producers choose this penetration grade because it combines flexibility, durability, and consistent performance in diverse projects.

Bitumen 85/100 is produced from vacuum residue of crude oil during refinery distillation. The controlled air-blowing process ensures its penetration range falls between 85 and 100 decimillimeters at 25 °C. This property defines how hard or soft the bitumen is — the higher the penetration, the softer the bitumen. As a result, Bitumen 85/100 provides an excellent balance between elasticity and cohesion, ensuring smooth paving performance even in cooler conditions.

Why Choose Bitumen 85/100?

Bitumen 85/100 is valued for its adaptability and smooth handling. It offers:

• Excellent flexibility at low temperatures, reducing the risk of cracking.

• Uniform viscosity for easy mixing and compaction with aggregates.

• Reliable adhesion that binds materials together for long-lasting pavements.

• Stable chemical structure, ensuring resistance to oxidation and aging.

• High durability in environments where temperature fluctuations are common.

When compared to harder grades like 60/70, this bitumen offers smoother workability and better resistance against thermal cracking, especially in high-altitude or colder regions.

These values show the stability and performance consistency required for modern construction.

Applications of Bitumen 85/100

This grade has a wide range of industrial and infrastructural applications.

1. Road Construction

It’s mainly used in asphalt pavements for:

• Base and surface layers of medium-traffic roads

• Rural and city roads in moderate climates

• Highway overlays and maintenance works
  Its smooth flow and binding power ensure a dense, durable surface with reduced deformation.

2. Waterproofing

Because Bitumen 85/100 is less brittle at low temperatures, it performs perfectly in:

• Roofing membranes

• Damp-proof coatings

• Foundation and basement waterproofing

3. Industrial Use

It serves as a raw material for various modified products such as:

• Emulsions

• Cutback bitumen

• Bitumen paints and primers

This versatility makes it one of the most economical and practical choices for large-scale projects.

Advantages of Using Bitumen 85/100

When selecting a penetration grade bitumen, contractors focus on climate and load conditions. For cold and moderate regions, Bitumen 85/100 has clear advantages:

1. Flexibility in Cold Weather: It maintains elasticity even below freezing, preventing cracks.

2. Ease of Handling: Melts easily at standard mixing temperatures and provides smooth coating on aggregates.

3. Strong Adhesion: Bonds aggregates firmly to create a durable surface layer.

4. Economic Efficiency: Longer service life means lower maintenance and resurfacing costs.

5. Consistency in Quality: ATDM ensures strict quality control for every batch shipped globally.

Frequently Asked Questions (FAQ)

1. What is Bitumen 85/100 used for?
It’s primarily used in road construction, asphalt production, waterproofing membranes, and industrial coatings. Its softer nature makes it ideal for regions where temperature variations are moderate to cold.

2. How is Bitumen 85/100 different from Bitumen 60/70?
Bitumen 85/100 is softer, meaning it has higher penetration and better flexibility. This helps prevent cracks in cold weather, while 60/70 is harder and better for hot climates with heavy traffic loads.

3. What temperature should Bitumen 85/100 be heated to during mixing?
For asphalt production, heating between 150 °C – 165 °C is recommended. Always ensure gradual heating to preserve the material’s structure and prevent oxidation.
