Bitumen 60/70

Bitumen 60/70

Bitumen has lots of grades and types one of which is bitumen 60/70.

This grade of penetration bitumen types is considered as a hard grade with a low penetration rate compared to other types and is suitable for hot climates such as tropical countries.

In the following, we will become more familiar with the meaning of the figures such as 60/70, 80/100, the specification, and the application of bitumen 60/70.

It’s good to know about the meaning of the different figures of the bitumen types in the first place. As a matter of fact, bitumen divides into several groups according to the various bitumen tests and their results. The aforementioned tests, determine the penetration, ductility, performance, viscosity, and other factors of bitumen. These tests are largely determinative in the bitumen specification and its application.

Generally speaking, Bitumen penetration grade 60/70 means the penetration rate varies in the range of 60 to 70 at standard test conditions.

This indicates that the tested grade is applicable for the production of hot mix asphalt for bases and pavements and road construction.

According to the bitumen tests, hardest grades are bitumen 60/70, 85/100, and all those types that are low in the penetration. Moreover, they are highly suitable for hot climates and regions. On the other hand, those grades with a high rate of penetration are appropriate for cold regions. In fact, they are softer grades. One of the most demanded types among the soft grades is bitumen 200-300.

According to what we have mentioned before, soft grades have a high demand in cold regions such as Canada, Russia, China, etc.

More about the bitumen 60/70 applications

The constructors usually apply bitumen 60-70 penetration grade for pavements where traffic is high. The reason is the hardness, strength, and specifications that allow it to be strong against the heavy loads. Needless to mention that this grade has a high demand in different countries in the world. Many countries import this type and apply it for their construction, pavings, and repairs. It’s essential to know which grade is suitable, otherwise, the project will collapse, causes extra costs, cracks, and serious troubles. As the final point, there are bitumen emulsions and cutbacks that are also suitable for various applications and regions, but bitumen 60/70 is the most well-known bitumen type in the world. Many countries prefer to lead their projects in a traditional way, by applying bitumen penetration grades 60/70.
