In this post, we will explore how Bitumen 60/70 is manufactured, its physical and chemical features, and its widespread applications across various industries. we will highlight how Peak Universal Business stands out as a premier supplier of high-quality Bitumen 60/70 products.

❓ What is Bitumen 60/70?

Bitumen 60/70 is a medium-hard penetration grade bitumen. The “60/70” grade refers to its penetration value, which indicates the consistency or hardness of the material. It is ideal for use in hot climates where softer grades might flow excessively and harder grades might crack.

📦 Key Characteristics:

• Penetration Value: 60–70 dmm

• Softening Point: 49–56°C

• Viscosity: Optimal for mixing and compaction temperatures

• Ductility: High ductility ensures flexibility

• Solubility: Over 99% in organic solvents like CS2

This grade of bitumen ensures a strong bond with aggregates, long-lasting pavement performance, and reliable waterproofing.

🏭 How Bitumen 60/70 is Produced

Bitumen 60/70 is typically produced through atmospheric and vacuum distillation of crude oil, followed by further refining processes. Here is a step-by-step look:

The production of Bitumen 60/70 involves several critical steps, from crude oil refining to the final grading of the bitumen. Let’s explore this process in detail:

1. Crude Oil Refining

The journey of Bitumen 60/70 begins with the refining of crude oil. Crude oil is a complex mixture of hydrocarbons that needs to be separated into various components through the refining process. This is typically done in a petroleum refinery through fractional distillation.

Fractional Distillation Process:

• Heating: Crude oil is heated in a furnace to a temperature where it vaporizes.
• Distillation Column: The vaporized crude oil enters a distillation column, where it cools and condenses at different levels based on boiling points.
• Separation: Lighter fractions (like gasoline, diesel) rise to the top, while heavier fractions (like bitumen) settle at the bottom.

2. Vacuum Distillation

The heavier fractions obtained from fractional distillation undergo further processing through vacuum distillation. This step is crucial for producing bitumen:

• Vacuum Conditions: The residue from fractional distillation is subjected to vacuum conditions to lower the boiling points of the remaining heavy components.
• Separation: Under reduced pressure, the heavy fractions are separated further, isolating the bitumen.

3. Air Blowing Process

To achieve the specific properties of Bitumen 60/70, the bitumen may undergo an air blowing process. This involves blowing air through the bitumen at high temperatures to modify its characteristics:

• Oxidation: Air blowing causes-controlled oxidation, increasing the viscosity and softening point of the bitumen.
• Consistency Adjustment: The process adjusts the penetration and consistency to meet the specifications of Bitumen 60/70.

4. Grading and Quality Control

The final step in the production of Bitumen 60/70 involves rigorous grading and quality control to ensure the product meets industry standards:

• Penetration Test: A standardized needle penetration test determines the hardness and consistency.
• Softening Point Test: The softening point is measured to ensure the bitumen maintains its properties under varying temperatures.
• Viscosity Test: Viscosity is tested to ensure the bitumen’s suitability for its intended applications.

📊 Technical Properties of Bitumen 60/70

Property	Unit	Specification
