Definition of bitumen penetration grade 80/100
It is common practice to utilize Penetration Bitumen Grade 80/100 as a Paving Grade Bitumen ideal for building roads and creating asphalt pavements with exceptional qualities.
Petroleum-grade bitumen, or penetration-grade bitumen, is produced by fractional or vacuum distilling crude oil and is provided by Petro Bitumen Company.
Bitumens of the Penetration Grade have passed the depth and softening threshold test.
Penetration bitumen has thermoplastic properties that soften the material at high temperatures and harden it at lower temperatures.
The temperature/hardness relationship of the bitumen depends on the type of crude oil and the refining method. It is a semi-rigid penetrating asphalt used as paving, suitable for road construction and repair.
It is also used to produce asphalt pavement with the below specifications.
This bitumen quality is mainly used to produce hot mixes for substrates and coatings.
Bitumen penetration grade 80/100 is one of the most widely used bitumen and is the base material for all other asphalt products.
Penetration determines the hardness of the asphalt by measuring the depth to which a standard load needle will penetrate vertically in 5 seconds in an asphalt sample maintained at a temperature of 25 degrees Celsius.
Application of bitumen penetration grade 80/100
Bitumen 80/100 is appropriate for making asphalt pavements with outstanding qualities and for paving roads.
Hot mix asphalt for foundations and grasping courses is made using this bitumen.
Guarantee and Safety for bitumen penetration
With the placement of international inspectors to check the quality and the amount of the bitumen penetration grade 80/100 during its transportation for shipping and control the production by QC by sequentially testing findings before shipping, Petro Bitumen Company guarantees the quality of bitumen penetration grade 80/100.
This Company guarantees the quality to meet with ASTM.
