Penetration Grades

Penetration-grade bitumen is mainly

used in road surfacing. Bitumen with

lower penetration grade is used in

the regions with warm climate while

higher penetration grade is used in

colder weather.

Pasargad Oil Company is capable of

producing different grades of road

surfacing bitumen in compliance

with national and international

standards in its 6 plants located at

Tehran, Tabriz, Arak, Shiraz,

Bandar Abbas and Abadan.


Performance Grade (PG)

PG is the latest standard of the bitumen. This

relatively new method classified bitumen is

based on varying temperatures. It is a fully

scientific method studying the mechanical

specifications of bitumen. In this method, a

temperature range is defined for bitumen and

the consumer can easily choose the desired

product.

Having installed SHRP systems, Pasargad Oil

Company is capable to sell bitumen to its

customers based on PG method.

Today, a PG is defined for polymer modified

bitumen and pure bitumen based on

environmental conditions and temperature. A

wider PG range means higher resistance and

more favorable specifications.

High Temperature Performance Low Temperature Performance

PG 46 -34, -40,-46

PG 52 -10, -16, -22, -28, -34,-40,-46

PG 58 -10, -16, -22, -28, -34, -40

PG 64 -10, -16, -22, -28, -34, -40

PG 70 -10, -16, -22, -28, -34, -40

PG 76 -10, -16, -22, -28, -34

PG 82 -10, -16, -22, -28, -34


Oxidized Bitumen

Oxidized bitumen is mainly used for

industrial purposes, such as roof

insulation, flooring, industrial mastics,

pipe coating, and paints. Oxidized

bitumen is categorized based on softening

points and penetration rate. For example,

oxidized bitumen 85/40 is a type of

bitumen whose softening point is 85±5

degrees Centigrade and its penetration

rate is 40±5 dmm.

The softening point in oxidized bitumen is

much higher than in regular bitumen,

causing lower thermal sensitivity. The

penetration index (PI) in oxidized

bitumen is higher than in road

construction bitumen (8>PI>2) because

the letter has a gel-like structure due to

asphalt accumulation.

How to produce Blended Bitumen?

Blending Materials with Bitumen:

- Other Bitumens (to produce special grades)

- Solvents (to produce Cutback bitumens: SC, MC, RC and Emulsion

grades)

- Polymers (to modify properties)

- Other Waste Materials (Sulfur, Powdered Lastics, Petrochemical waste

materials)

Blending Process is done in line and storage tanks.

- The quality of Polymer modified Bitumen and Emulsified Bitumen has been

approved.

- But blended bitumen with petroleum products, and waste materials do not pass all

quality parameters and they are known as low quality bitumens.

Low Quality Bitumen

• Produced by air blowing of Heavy fuel to obtained low

quality mixture

• Blending of sludge

• Uncompleted Distillate Process , VR , …

• Blending With Low Quality Bitumen Binder
