Description of PENETRATION BITUMEN 70/100

Penetration bitumen 70/100 is a soft form of paving grade bitumen that may be utilized in a wearing course, even in low temperature locations. It is possible to include it into AC and SMA mixtures provided that the mixture is rutting resistant. Penetration Bitumen 70-100 is a kind of refinery bitumen that has a permeability that falls anywhere between 70 and 100 and is created by vacuum aerating a distillation tower. This kind of petroleum grade bitumen is created from crude oil that has been refined by a fractional vacuum process.

The bitumen penetration grade 70-100 that is supplied by PetroNaft Co. is made from the vacuum batuum feedstock that is utilized in the process. In order to define the bitumen as being of the penetration grade, the penetration test is performed. The designation is based entirely on the range of penetration. The depth to which a standard-loaded needle will vertically penetrate in five seconds inside a sample of bitumen stored at a temperature of 25 degrees Celsius is used to test penetration, which specifies the hardness of bitumen.


Our firm, Petro Naft, manufactures high-quality penetration bitumen called Bitumen 70/100. This kind of bitumen is often used in the construction sector to pave roads, highways, and runways. To satisfy the demands of our clients, our business makes sure that Bitumen 70/100 is produced to the highest standards of quality.

Bitumen 70/100 is produced from carefully chosen crude oil that is processed in our cutting-edge refinery. As a consequence, high-grade bitumen that satisfies global requirements for road building is produced. To guarantee that the product meets quality criteria including penetration, softening point, and viscosity, tests are conducted at every step of manufacture.

Our Bitumen 70/100 has good adherence to a variety of surfaces and is quite resistant to temperature fluctuations. Since it retains its stability and resists deformation at high temperatures, it is a favoured option for road building in hot areas.

Eco-friendly and sustainable manufacturing methods are important to Petro Naft. Our manufacturing procedure complies with all relevant environmental regulations, guaranteeing that our goods have little effect on the environment.

We take great pleasure in the high caliber of our offerings and the superior level of our client support. Our knowledgeable staff is always accessible to provide our clients professional guidance and assistance. At Petro Naft, we’re dedicated to exceeding clients’ expectations and satisfying their demands with goods.

We produce penetration bitumen 70/100 of the best quality in a variety of types and export them from Iran and the United Arab Emirates to other nations worldwide.

  • Iran Penetration Bitumen 70/100 ( Iran Bitumen 70/100 )
  • Emirates Peneteration Bitumen 70/100 ( Emirates Bitumen 70/100 )


Bitumen that has a low degree of penetrability is referred to as hard bitumen, whereas bitumen that has a high degree of penetrability is referred to as soft bitumen and is used in cold regions. Soft bitumen is used in cold areas, while hard bitumen is utilized in warm climates.

The following are some of the advantages of Penetration bitumen 70/100:

  • It can be used in both cold weather and mild weather.
  • It has remarkable flexibility and can be used in industries that demand a coating that is very flexible.
  • It has very strong adhesion.

Applications of PENETRATION BITUMEN 70/100

Since the Penetration Bitumen 70/100 produced by PetroNaft Co. possesses very high performance in terms of resistance to aging, plasticity, and behavior at low temperatures, it is utilized in the production of bituminous mixes that constitute a flexible structure for the paving of roads, runways, pavement, track race, and landing platforms. Because of this, Penetration Bitumen 70.100 performs exceptionally well in these conditions. In order to accomplish this goal, the appropriate amount of bituminous mixes is used.

PetroNaft Company manufactures the highest quality Penetration Bitumen 10/20 in different types and exports it from Iran and the UAE to other countries around the world.
