Bitumen 60/70

General definition of Bitumen 60/70

Bitumen 60/70 is a standard Penetration Grade of Bitumen ASTM D946M, produced through aeration on vacuum bottom in Asphalt production units. Its penetration grade ranges from 60 to 70 and is primarily used for road construction and asphalt pavements. This grade is mainly used in the production of hot mix asphalt for bases and wearing courses. The bitumen mode is dependent on temperature, with the temperature-vs-stiffness relationship influenced by the type of crude oil and refining method.

The quality of 60/70 bitumen is primarily dependent on its physical and properties, such as viscosity, softness, shaping, and temperature loss at the flash point. It is widely used in road construction projects in countries with moderate temperatures. Penetration Grade Bitumen is produced from vacuum residue blown by hot air in the Biturox Blowing Unit, resulting in a constant and homogeneous finished product quality.

Soft bitumen, with a high degree of penetration, is used in cold climate regions, while relatively solid bitumen, with a low penetration degree, is mainly used in areas with high temperature climates.

How does 60/70 Penetration Graded Bitumen perform under different conditions?

60/70 Penetration Graded Bitumen performs well under various conditions, maintaining its integrity and functionality in both high and low temperatures. It exhibits good resistance to cracking in cold climates and remains stable and non-deformable in hot environments, making it a versatile choice for different geographical regions.

Properties of Bitumen Grade 60/70

all refineries are in charge of testing this grade of bitumen after production and provide buyers with specifications table. This table includes items such as penetration value, flash point, softening point, ductility and specific gravity. Penetration value indicates the level of bitumen hardness. For bitumen 60/70, penetration is between 6 to 7 mm. Various types of bitumen have also different softening points, which indicates the temperature at which bitumen starts to melt. The softening point of Asphalt grade 60/70 is between 49 to 50°.

Application of Bitumen grade 60/70

This grade of bitumen is also mainly used in the manufacture of hot mix asphalt.

also, Bitumen is suitable for road construction and repair for asphalt pavements with superior properties. Bitumen is used for hot mixed asphalt because of the properties of very strong viscosity compared to other grades.

Also used in specialized applications like airport runways and also in very heavy traffic volume roads in coastal cities in the country.

This kind of bitumen is suitable to be used for road construction projects in mild regions.

Also it can be used for producing some kind of asphalt primer and Waterproofing products.

Asphalt 60/70 is a moderate penetration grade bitumen commonly used in road construction due to its high tolerance for heart and strength. It is commonly used for paving and maintenance due to its high tolerance. Other specifications for this grade include viscosity, flash point, ductility, softening point, and loss of heating. It is widely used due to its versatility and suitability for various applications.

Difference between Bitumen 60/70 & Bitumen 80/100

Bitumen 60/70 and Bitumen 80/100 are two grades of bitumen. The only basic variation between them is their range of values that come for penetration. Bitumen 60/70 has a penetration value of 60-70 dmm, which is harder and more viscous compared to Bitumen 80/100 having a higher penetration value of 80-100 dmm.

This, in turn, becomes the reason for laying the difference in hardness concerning a particular selection. Asphalt 60/70 is workable and more resistant to deformation; it is good to go for high-traffic areas and very hot climatic zones. On the other hand, Bitumen 80/100 will be ideal for cold climatic areas with low volume traffic because of its flexibility and resistance to cracking.

Packing

There are several different ways to package the bitumen which can vary depending on the tonnage, type, and grade of the bitumen- as mentioned before, different grades of bitumen have different levels of stiffness and viscosity- so the grade also plays an important role in choosing a suitable packaging.

Bitumen grade 60/70 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or 300 Kg Bitubag.

  •  1 MT Jumbo Bag
  •  1300 Kg Jumbo Bag
  • 180kg New Steel Drum
  •  300Kg Bitubag

Specification of Asphalt 60/70

Bitumen guarantees that the Bitumen Grade 60/70 is produced in compliance and conformity to International Standards such as AASHTO M20-70 & ASTM D946, also, meets the following specification requirements. The specifications of our bitumen are as followed in the table below.
