Bitumen 80/100

Bitumen 80/100

As we all know, the major use of bitumen 80/100 and other grades is due to the existence of two significant

factors of this material, impermeability to water and high adhesion.

With attention to the mentioned properties, the main use of bitumen is in road construction and insulation.

Bitumen 80/100 is solid and semi-solid bitumen that the specialists obtain directly

from the distillation of crude oil or by other additional operations such as blowing air.

It’s good to know that residual or heavy oil bitumen is the distillation of crude oil.

The amount of crude oil bitumen varies from zero to more than half of it.

Besides, bitumen that they obtain from different sources can have many differences.

Therefore, bitumen refineries must carefully choose their crude oil to ensure the quality of bitumen.

Having various forms, bitumen has a type which is TAR.

Moreover, this substance has some similarities in appearance and use to petroleum bitumen.

Because the source of this type of bitumen is different from petroleum bitumen,

it has a different chemical composition and physical properties, so it is a general term for liquids

that Tar behaves differently during use and service than burning natural organic materials such as wood or charcoal.

Bitumen applications

The specialists can prepare two types of tar bitumen according to the type of process of burning or carbonization

of coal: One process that results in bitumen with a high percentage of aromatics is bitumen

that they obtain at a temperature of 2 ° C and has a lower percentage of aromatics,

which after cooling the vapors and separating the oil slices is the residual material of coal bitumen. Historically speaking,

in the era of the European Industrial Revolution, the emergence of large amounts of oil and gas resources,

they almost “abandoned” coal and its consumption greatly reduced.

Today 90% of bitumen types such as bitumen 80/100 applications are in four groups: road construction,

charcoal dust, charcoal electrodes, and glaze and pipe coating,

but the use of refinery coal bitumen on roads only depends on the mixture for surface coatings.

The reason is that these bitumen types such as bitumen 80/100 are more soluble and perform

better at lower temperatures and as a result have better adhesion, but the main weakness of these bitumen types,

is their greater thermal sensitivity than petroleum bitumen.
