What is Bitumen 60/70?
Bitumen 60/70, also referred to as penetration grade bitumen, is a semi-hard substance derived from refining crude oil. The “60/70” in its name represents the penetration value of the bitumen, indicating how far a standard needle can penetrate the material under specific conditions. This penetration grade is perfect for moderate climates, as it provides optimal flexibility and durability for paving and waterproofing applications. Bitumen 60/70 is a popular choice for road construction and asphalt projects due to its balance between hardness and elasticity, making it resilient against cracking and deformation.

Types of Packaging for Bitumen 60/70
Packaging is a critical aspect of bitumen logistics, as it ensures the material remains stable and easy to transport. Bitumen 60/70 is available in various packaging types that cater to different operational needs and project scales. Below are the most common forms of packaging:
1. Drum Packaging
Drum packaging is among the most widely used methods for transporting Bitumen 60/70. These drums are made from steel and can hold approximately 200-220 kg of bitumen each. Drum packaging is ideal for both small and large projects, offering ease of handling and a controlled method of dispensing the bitumen. They are convenient for long-distance transport and storage, maintaining bitumen quality by protecting it from contamination and moisture.
2. Bulk Containers
For larger projects or continuous supply needs, bulk containers offer a cost-effective and scalable solution. Bitumen 60/70 can be stored and transported in bulk tankers or containers, which are typically heated to maintain bitumen viscosity during transit. This method is suitable for road construction projects with consistent bitumen requirements.
3. Polybag Packaging
Polybag packaging is a newer form of bitumen packaging that involves placing bitumen into high-density polyethylene bags, allowing easy storage and transport. These bags are environmentally friendly and reduce handling costs, making them an ideal option for smaller projects or where storage facilities are limited.
4. Kraft Paper Bags
Bitumen 60/70 can also be packaged in kraft paper bags, which are heat-resistant and come with an inner polyethylene layer. This option is particularly suitable for exporting bitumen and for remote areas where conventional bulk or drum options may be challenging.
5. Jumbo Bags
Jumbo bags, often made from durable woven polypropylene, are designed to carry large quantities of bitumen. They are commonly used in major construction sites where bulk material needs to be readily accessible, with each jumbo bag holding up to one metric ton of bitumen. This option is both economical and practical for large-scale applications.
6. Flexi

Usage and Applications of Bitumen 60/70
The Bitumen 60/70 serves as a cornerstone material in a wide range of applications, primarily within the construction sector. Below are the primary uses of this penetration grade bitumen:
1. Road Construction and Paving
One of the primary uses of Bitumen 60/70 is in road construction. Its balanced penetration level ensures it provides a stable surface that withstands various traffic loads, temperature changes, and weather conditions. Bitumen 60/70 is often mixed with aggregates to form asphalt, which is then spread and compacted to create roads and highways.
2. Asphalt Pavement
For areas that require durable pavement, Bitumen 60/70 offers excellent binding properties. It is mixed with graded stones and sand to form asphalt concrete, commonly used in roadways, parking lots, and airport runways. This application takes advantage of bitumen’s resilience, creating a surface resistant to weathering, cracking, and deformation under vehicle loads.
3. Waterproofing and Roofing
In addition to its use in roads, Bitumen 60/70 is an effective waterproofing material, commonly applied in the roofing industry. Its impermeability to water makes it an excellent choice for protecting roofs, basements, and foundations from moisture intrusion. The material is applied as a layer or membrane, providing long-lasting resistance against leaks.
4. Sealant and Adhesive
Bitumen 60/70 is also utilized as a sealant and adhesive for various construction applications. Its sticky and durable nature makes it ideal for sealing cracks in pavements, joining materials in road structures, and protecting surfaces from environmental damage. The bitumen binds materials together, providing a stable and weather-resistant seal.
5. Industrial Usage
Beyond road construction and waterproofing, Bitumen 60/70 is used in multiple industrial applications, including soundproofing, pipeline coating, and anti-corrosion coating. Its flexibility and resilience provide essential protection in harsh conditions, making it suitable for various demanding environments.
