Bitumen 60/70: The Ideal Choice for Road Construction by PetroBNX

In the world of road construction, the quality and reliability of materials play a crucial role in ensuring long-lasting infrastructure. One such material that stands out for its superior performance is Bitumen 60/70. This penetration-grade bitumen is widely used in the construction and maintenance of roads due to its excellent balance of hardness and flexibility. At PetroBNX, we specialize in the supply and export of high-quality bitumen, including Bitumen 60/70, offering the best options for road construction projects worldwide.

What is Bitumen 60/70?

The term Bitumen 60/70 refers to the penetration range of the material, with the first number (60) representing the lower limit and the second number (70) representing the upper limit. These values indicate the hardness of the bitumen. The 60/70 grade is classified based on its penetration value, measured in decimillimeters, and is known for its versatility in various applications, making it a top choice for road construction.

Applications of Bitumen 60/70

Bitumen 60/70 is primarily used in the construction of asphalt mixtures, which are crucial for flexible pavement construction. Due to its intermediate level of hardness, this grade of bitumen can withstand the stresses of heavy traffic loads and adverse weather conditions, making it ideal for high-performance asphalt used in roads, highways, and airports. Its ability to withstand temperature variations also helps prevent cracking and rutting on road surfaces.

Apart from road construction, Bitumen 60/70 is also used in the production of emulsions, cutbacks, and modified bitumen products. It plays an essential role in surface treatments, joint sealing compounds, and waterproofing materials. Its versatility makes it a critical component in maintaining and enhancing the longevity of road infrastructure.

How is Bitumen 60/70 Produced?

The production of Bitumen 60/70 starts with the refining of crude oil through a process called fractional distillation. This process separates crude oil into different fractions based on their boiling points. The heaviest fraction is then processed to produce bitumen. To create the 60/70 grade, the bitumen undergoes a series of tests to measure its penetration value, indicating its hardness. The penetration value refers to the depth, in tenths of a millimeter, that a standard needle penetrates the bitumen sample under specific conditions.

Properties of Bitumen 60/70

Bitumen 60/70 exhibits several key properties that make it ideal for use in road construction:

• Intermediate Hardness: It strikes a balance between flexibility and stability, ensuring it can handle heavy traffic loads and temperature fluctuations without excessive deformation.
• Adhesive Qualities: It provides strong bonding between aggregates, which adds strength to the asphalt mixture.
• Water Resistance: The bitumen prevents water from infiltrating the road structure, which helps in preventing long-term damage caused by moisture.
• Thermal Stability: It can expand and contract with temperature changes, which reduces the risk of cracks and rutting on the surface.

Specifications of Bitumen 60/70

Bitumen 60/70 is manufactured to meet various international standards, including the British Standard (BS), American Association of State Highway and Transportation Officials (AASHTO), and European standards (EN 12591). These specifications outline the required penetration values, softening points, and ductility to ensure the bitumen meets the necessary performance criteria for different climatic conditions and traffic loads.

At PetroBNX, we ensure that all of our Bitumen 60/70 products adhere strictly to these specifications, ensuring their quality and reliability for use in global road construction projects.

Packaging and Delivery

To meet the varying needs of our clients, PetroBNX provides Bitumen 60/70 in several packaging options, including bulk shipments, drums, and bitu-bags (big bags).
