Description of PENETRATION BITUMEN 50/70

Penetration Bitumen 50/70 is a bitumen of superior quality that is produced in refineries that are owned and run by PetroNaft. These refineries use the most cutting-edge industrial procedures and the most appropriate crude oils in the production of bitumen 50-70. It has the perfect viscosity across the temperature range where the activities of mixing and laying take place, which guarantees that it can be readily dealt with despite the high levels of pressure that are applied.

The product not only achieves the maximum possible degree of hardening resistance but also fulfills the criteria of the European standard EN (severity 1). Because of its blowing quality and moderate air penetration, this kind of bitumen is neither exceedingly soft nor exceptionally hard. The price of Bitumen 50.70 is much cheaper than that of other types of Bitumen since it does not need any adjustments.


One of the top producers of the most sought-after penetration bitumen grade, bitumen 50/70, is Petro Naft. This kind of bitumen is often employed in the building of roads because of its superior adhesive and waterproofing qualities, which make it a perfect addition to asphalt mixes.

At Petro Naft, we are proud of our capacity to manufacture bitumen 50/70 of the highest quality while adhering to the most exacting industry requirements. We are regularly able to provide a product that meets or surpasses the expectations of our clients thanks to our cutting-edge production facilities and skilled workforce.

Bitumen that has been particularly formulated to resist high temperatures is known as penetration bitumen, and it is the perfect material for usage in hot areas. This particular form of bitumen is also very resistant to water and other environmental elements, guaranteeing that it will survive for a very long time even under the most trying circumstances.
