What is Bitumen 60/70? | Applications, Properties & Uses Explained

🛢️ What is Bitumen 60/70 & Its Uses & Applications

Bitumen, often referred to as asphalt or asphalt binder, serves as a fundamental component in various infrastructure projects worldwide. With its diverse range of grades and specifications, bitumen caters to the specific requirements of different applications, from road construction and waterproofing to industrial coatings and adhesives. In this extensive exploration, we delve deep into the world of bitumen 60/70, uncovering its uses, applications, benefits, and insights into sourcing from Peak Universal Business, a trusted supplier in the industry.

❓ What is Bitumen 60/70?

Bitumen 60/70 is a penetration grade bitumen produced through the air-blowing process of vacuum bottom residues from crude oil distillation. The numbers 60/70 represent the penetration value of the bitumen in 1/10 mm at 25°C, which means that a standard needle will penetrate the bitumen sample to a depth between 60 and 70 tenths of a millimeter under specific conditions.

This bitumen grade is classified as semi-hard and is primarily used as a binder in asphalt concrete for roads, highways, and airport runways.

⚙️ Technical Specifications of Bitumen 60/70

🧪 Explanation:

• Penetration & Softening Point: These indicate the consistency and thermal behavior.

• Ductility: High ductility means good flexibility under stress.

• Flash Point: Ensures safety during transportation and heating.

• Solubility: Confirms bitumen purity and minimal impurities.

🏗️ How is Bitumen 60/70 Produced?

The production of Bitumen 60/70 involves distilling crude oil in a refinery where heavier fractions are separated. The residue, called vacuum bottom, is then air-blown in reactors to oxidize it slightly, modifying its viscosity and consistency. The result is a semi-solid grade of bitumen with penetration characteristics in the 60–70 range.

✅ Key Steps:

1. Atmospheric and vacuum distillation of crude oil

2. Air-blowing the vacuum residue at controlled temperature

3. Cooling and grading based on penetration tests

This manufacturing method ensures consistent quality, essential for large infrastructure projects.
