Penetration grade bitumen
What is Penetration grade Bitumen?
Base oil is an oil that is considered a base for lubricants. After adding additives to the base oil, the final lubricant is obtained. Base oils are the most critical component of lubricants in terms of volume, and in terms of weight, on average, they make up more than 95% of the formulation of a roller.
Since most of the base oils used in the production of lubricants are obtained from petroleum sources, the base oil industry is considered a part of the petroleum industry.
Determining Penetration grade Bitumen:
The test to determine the degree of penetration of bitumen is done to determine their relative hardness and one of the methods of naming different types of them is to use the value of penetration grade bitumen.
The test to determine the degree of penetration of bitumen is done to determine their relative hardness and is one of the most widely used tests related to bitumen one of the methods of naming types of bitumen is to use the value of their degree of penetration.
Because bitumen has a viscoelastic nature, its behavior depends on changes in the degree of gravity and the amount of loading per unit of time.
For example, In hot weather, bitumen acts like a viscous liquid, and in this case, permanent deformation and less reversible grooves in it.
In cold weather, bitumen acts like a solid elastic material and changes its shape during the passage of vehicles.
Tests of penetration grade bitumen are often performed at different temperatures of 25 degrees, and penetration grade bitumen does not indicate its behavior of it at other temperatures.
Reasons for importance of penetration grade bitumen:
The most important application of penetration grade bitumen is to find out the area where bitumen is used, such as hot areas or roads with a lot of traffic.
Bitumen with a higher degree of penetration is used for cold areas and it is used less.
So, the bitumen becomes harder, its degree of penetration decreases, and the softer the amount of bitumen, the higher its degree of penetration.
The purpose of this test is to determine the penetration rate of bitumen and bituminous materials in solid and semi-solid forms.
The penetration degree of bitumen test is used to measure the consistency so that a higher penetration degree indicates a lower consistency and a lower penetration degree bitumen indicates a higher consistency.
Different types of bitumen:
The types of penetration grade bitumen are based on the range of their penetration.
- Bitumen penetration grade 30/40
- Bitumen penetration grade 40/50
- Bitumen penetration grade 60/70
- Bitumen penetration grade 85/100
- Bitumen penetration grade 100/120
Bitumen penetration grade 30/40
It is a standard type of bitumen penetration grade. This grade is manufactured from the fractional vacuum of crude oil.
Bitumen 30/40 is semi-hard penetration grade bitumen used as a paving grade bitumen, for constructing and repairing a road. It is also used to produce asphalt pavements with the below technical specification.
Bitumen 30/40 is used for manufacturing hot mix asphalt for wearing courses and bases. Bitumen grade 30/40 is one of the most used bitumen as a basic material for all other bituminous products.
Application of bitumen penetration grade 30/40
bitumen penetration grade 30/40 is used for constructing roads and repairing asphalt pavements with superior properties. Bitumen 30/40 is mainly used for manufacturing hot mix asphalt for wearing courses and bases.

Bitumen penetration grade 40/60
Bitumen Penetration Grade 40/60 is used for road construction and producing asphalt pavements and is mainly used for manufacturing hot mix asphalt, bases, and course wearing.
Bitumen Penetration Grade 40/60 is for the production of asphalt pavements with superior properties and creates a unique and sustainable bituminous mix.
This product is used on tropical regions’ roads.
Bitumen penetration grade 60/70
penetration grade bitumen 60/70 has a penetration value in the range of 60 to 70 at standard test conditions.
penetration grade Bitumen 60/70 is semi-hard penetration grade bitumen.
This type of bitumen is one of the most used bitumen grades and it’s a basic material for all other bituminous products.
Application of bitumen penetration grade 60/70
Bitumen 60/70 is suitable for constructing roads and making asphalt pavements.
This kind of bitumen is used in the manufacture of hot mix asphalt for bases and wearing courses.
An important usage of penetration grade bitumen 60/70 is used in the road in mild regions. Also, Due to its medium air blowing and penetration, it is used in mild areas too.
Bitumen penetration grade 80/100
Bitumen Penetration Grade 80/100 is used for making hot mix asphalt for bases and wearing courses. The classification of bitumen is based on penetration range. Bitumen 85/100 has a thermoplastic property.
This property causes the material to soften at high temperatures and to harden at lower temperatures. Penetration grade bitumen 80/100 is one of the most used bitumen and it’s used for basic material at all other bituminous products.
Application of bitumen penetration grade 80/100
Bitumen 80/100 is suitable for constructing roads and for making asphalt pavements. This type of bitumen is used for manufacturing hot mix asphalt for bases and wearing courses.
Bitumen penetration grade 100/120
Bitumen 100/120 is good for paving and it is suitable for road construction and the production of asphalt pavements.
This grade of bitumen is used in the manufacture of hot mix asphalt for bases and wearing courses.
The penetration grade of bitumen has a thermoplastic property. this property causes the substance to soften at high temperatures and to harden at lower degrees.
Application of bitumen penetration grade 100/150
Penetration Grade Bitumen 100/150 is suitable for constructing roads and asphalt pavements. This type of bitumen is used in the manufacture of hot mix asphalt for bases and wearing courses
