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 […]
