Penetration Bitumen:

Introduction of Penetration Bitumen and its Applications

The unique feature of Penetrating bitumen produced in Pars Bitumen Company is its easy and vast application in road construction in different environmental conditions. The main purpose of grading bitumen based on penetration is to determine its suitability for use in various industries and conditions. Different grades of bitumen are named according to their hardness level and consistency, and in this way, penetrating bitumen is classified in grades between 30 to 120. These grades are determined based on the penetration depth of the needle.

 

What is penetrating bitumen?

Penetration Grade Bitumen, supplied by Pars Bitumen Company which is also known as pavement bitumen, is a type of standard bitumen that is usually used in road construction and pavement, and is a petroleum product obtained from the distillation of crude oil.

Penetration bitumen is classified based on their hardness and ability to withstand different traffic and weather conditions. The characteristics of this type of bitumen are determined by its penetration value, which is the depth in millimeters that a standard needle penetrates into the bitumen sample under certain conditions of time, temperature and load.

 

Penetration bitumen supplied by Pars Bitumen Company is graded based on its penetration value at 25 degrees Celsius, which usually ranges from 10 to 300. The higher the amount of penetration, the softer the bitumen and vice versa. The most common penetrating bitumen grades in road construction and paving are 50/40, 60/70 and 100/80 bitumen grades.

In addition to road construction and paving, penetration bitumen is also used in other applications such as waterproofing, roofing and insulation. This raw material plays a significant role in the development of infrastructure in the construction industry.

 

The importance of using penetrating bitumen:

In addition, the use of penetrating bitumen supplied by Pars Bitumen Company in road construction projects can also help save energy due to its better efficiency and compatibility with aggregates. This type of bitumen also has better pavement performance and the roads will have a longer useful life.

 

Knowing the degree of bitumen penetration used in projects allows you to predict the behavior of the desired bitumen in different conditions. For example, bitumen with lower penetration is needed when building roads in hot climates. This helps prevent the asphalt from softening too much at high temperatures.

 

 

Importance of quality of penetration Bitumen:

The quality of penetrating bitumen supplied by Pars Bitumen Company is very important for use in road construction industry, paving, waterproofing, roofing and other applications. The quality of this type of bitumen can be evaluated based on different physical and chemical properties. In the following, we mention some important indicators in determining the quality of penetrating bitumen.

The amount of bitumen penetration supplied by Pars Bitumen Company indicates its hardness and resistance to deformation. This penetration rate is measured in tenths of millimeters as the depth a standard needle penetrates into a bitumen sample under specific conditions of time, temperature and load. The amount of bitumen penetration should be within the range specified for its intended use.

 

Softening point of penetrating bitumen:

Bitumen softening point indicates the temperature at which bitumen becomes soft and flexible. This temperature is also determined through the penetration of a standard needle in bitumen under certain conditions. Bitumen for different applications must have certain conditions and characteristics, and the softening point of penetrating bitumen for the intended application must be within the specified range.

 

Softening point of penetrating bitumen

 

Plasticity

Bitumen ductility indicates its elasticity and flexibility. This property is measured in centimeters as the distance a bitumen sample can be stretched without breaking. The ductility of penetrating bitumen should be within the specified range for its intended use.

 

Solubility of penetrating bitumen

Bitumen solubility indicates its purity and homogeneity. This property of penetrating bitumen is measured by dissolving it in a specific solvent (typically trichloroethylene). Bitumen solubility should be within the range specified for the intended application.

 

Flash point of bitumen

The flash point of bitumen indicates its safety for handling and storage in different conditions. This characteristic of penetrating bitumen is measured by examining the minimum temperature at which the bitumen produces enough vapor to ignite in a flame. The flash point should also be checked for the intended application.

 

Specific weight of penetrating bitumen

The specific gravity of bitumen supplied by Pars Bitumen Company indicates its density and consistency, which is measured by examining the ratio of the weight of a certain volume of bitumen to the weight of an equal volume of water. The specific weight of penetrating bitumen should be within the specified range for its intended use.

 

History of penetrating bitumen

The use of bitumen dates back to ancient times, when this material was used as insulation for sealing boats and buildings. Ancient Babylonians and Egyptians used bitumen as an adhesive and waterproof material in their construction projects. The modern use of bitumen in the construction of roads and paving also dates back to the 19th century. The development of bitumen penetration grading in the 1920s and 1930s was a turning point in the history of bitumen.

 

Penetration grading provided a standard method for determining the consistency and hardness of bitumen and made it easier to use in road and pavement construction. In the middle of the 20th century, the demand for bitumen increased with construction and the material was used in roofing, waterproofing and other applications. The development of polymer-modified bitumen in the 1960s and 1970s further expanded the range of bitumen applications.

 

Where is penetrating bitumen used?

Pars Bitumen Penetrating bitumen is usually used in road surfacing projects and industrial projects. This type of standard bitumen is essential for high-quality asphalt pavements and binds the aggregates and contributes to the stability and cohesion of the bitumen mixture. Among all the different grades of penetrating bitumen, the 60/70 grade is one of the most widely used subgrades in road construction projects.

Because 60/70 grade penetrating bitumen provides more strength, it is ideal for high-traffic road asphalt. In addition, this bitumen has a very good performance and works quickly; This means that the roads can be paved and opened quickly.

 

Bitumen grade 85/100 supplied by Pars Bitumen Company is also common. This penetrating bitumen has a high heat retention property because it can retain heat longer and allows the asphalt to be easily molded into the road. Also, its heat preservation property makes the asphalt not crack even at low temperatures.

Penetration bitumen grade 85/100 is an excellent option for building strong and durable roads in high altitude areas and cold climates.
