Bitumen Grade 60/70 is one of the derivatives of crude oil that can be obtained through distillation towers present in refineries. This type of bitumen is known as asphaltic bitumen, consisting of components such as asphaltene and maltene. The 60/70 designation determines its body and softening point, which should be considered. 60/70 bitumen, also known as bitumen coating, performs well in most industries and is utilized at various temperatures. Here, we intend to delve into the examination of Grade 60/70 bitumen partially, so stay with us until the end.
Specifications of Bitumen Grade 60/70
This bitumen can exhibit softness and flexibility at ambient temperature, and when placed at temperatures between 46 and 59 degrees Celsius, it can also achieve complete fluidity. The designation 60/70 means that this bitumen can penetrate from 60 to 70 hundredths of a millimeter.
In Bitumen Grade 60/70, the consistency of the bitumen also depends on its temperature. It should be noted that the relationship between temperature and the degree of hardness in the bitumen is dependent on the type of crude oil used in bitumen production and the refining process applied.
Furthermore, this type of bitumen possesses very high adhesion. This means that when poured onto cement, it adheres easily, which is an important consideration. If the mentioned asphaltic bitumen closely conforms to international standards, we can also consider it to be very high quality.
Technical Specifications of Bitumen 60/70
Production Process of Bitumen 60/70
Bitumen can be produced using batch and continuous methods, each with its specific conditions.
- In the batch process, a tower is filled with a specific volume of feedstock, and after air blowing under particular conditions and achieving the desired specifications, the building is emptied, and its contents are transferred to tanks.
- In the continuous process, a specific amount of feedstock at a certain temperature is continuously fed into the air-blowing tower and removed from the building after the blowing operation. This method is commonly used in refineries, simplifying the process control and reducing the blowing time with less air consumption.
Examining the Application of Bitumen Grade 60/70
Some of the applications we can consider for Bitumen Grade 60/70 include:
- This material is easily used in most road construction and waterproofing projects due to its softness and suitable penetration grade.
- This bitumen is predominantly used on roads and in moderate climate zones.
- We can consider this type of bitumen to have a very high resistance to weather conditions.
Conclusion
In this context, we have examined Bitumen Grade 60/70. Important points to consider regarding this bitumen include its suitability for road construction and building projects. Its penetration grade ranges from 60 to 40 hundredths of a millimeter at temperatures between 46 to 56 degrees Celsius. When preparing this bitumen, it is crucial to fully consider its penetration grade and adhesion level, as this aspect is of utmost importance.
