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 tropical

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 distinct 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.

Bitumen tests and results

According to the bitumen tests, the hardest grades are bitumen 60/70,

85/100, and all those types that are low in penetration. Moreover, they are highly suitable for tropical 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.


What Is Bitumen


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 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 ultimate 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.

In sum, bitumen 60/70 has the highest demand among other types. Moreover, the Middle Eastern countries are predominant in the field of exporting

bitumen and petrochemicals, especially penetration grades. That is why the

rate of exports from the Mideast is noticeable.
