Bitumen has many uses in our daily lives. From asphalt paving to roofing insulation, it is undeniable that bitumen is very important for industrial uses. Therefore, its quality also matters. However, did you know that different types of bitumen have different functions and one of them is cutback bitumen? But what is cutback asphalt and […]

Natural bitumen, mineral bitumen or Gilsonite is a natural resinous hydrocarbon. This bitumen is similar to hard petroleum asphalt and is classified by geologists as a substance soluble in petroleum solvents. In this article, we will talk more about natural mineral bitumen, Gilsonite applications, Gilsonite mine in Iran, global natural bitumen price, and what mineral […]

Have you noticed the quality of the roads when you travel by car? For instance, some streets have high quality, and viehcles pass lightly. However, some are not paved with high-quality asphalt, and usually have bumps. Since bitumen is one of the main components of asphalt, it is a significant factor to determine its quality. Also, there are many […]

Penetration grade bituminous products are made for road construction for various environments and have different grades. The manufacturers grade these products based on their hardness and resistance. Therefore, penetration bitumen products are categorized into 30 to 120 grades. The principal purpose of this grading is to create bitumen products suitable for use in various environments and Industries. Experts […]

Oxidized bitumen or blown bitumen is produced by blowing hot air into pure bitumen in the final stages of its refinement. In this process, the manufacturers blow hot air at the temperature of 200 to 300 Celsius through a perforated pipe into the bitumen container. As a result, the hydrogen atoms in bitumen’s hydrocarbon molecules […]

Performance grade bitumen, which is also called PG bitumen is a type of bitumen that manufacturers grade based on its performance at special conditions. The manufacturers perform this grading based on understanding bitumen’s behaviour and its performance characteristics. Therefore, they assess bitumen’s behaviour and determine the types of PG bitumen. In this article, we will […]

For producing hot mix asphalt, road constructors use VG bitumen. Viscosity bitumen is a type of bitumen with many uses. This bitumen is thermoplastic which makes it flexible in warm climates and hard and fragile in cold regions. Viscous bitumen is also thick and adhesive. Its adhesion allows it to combine with other materials that […]
