Penetration Grade Bitumen 200-300
What is Penetration Grade Bitumen 200/300?
Penetration Grade Bitumen 200/300 is a type of bitumen that falls under the penetration grade bitumen category. It is commonly used in road construction, asphalt production, and waterproofing applications.
The numbers 200/300 refer to the penetration range of the bitumen measured in tenths of a millimeter at 25°C. Specifically, the penetration value of Penetration Grade Bitumen 200/300 is between 200 and 300 dmm (decimillimeters). This means that the bitumen has a relatively harder consistency compared to lower penetration grade bitumens such as 60/70 or 80/100.
The quality of Penetration Grade Bitumen 200/300 can vary depending on the source and manufacturing process. Typically, it is a dark-brown to black viscous liquid that is soluble in carbon disulfide and has a low solubility in water. It has a high softening point, which makes it suitable for use in high-temperature environments. It is also characterized by good adhesion, water resistance, and durability.
Like other penetration grade bitumens, Penetration Grade Bitumen 200/300 is commonly packed in bulk tankers, steel drums, or other appropriate containers for transport and storage.

History of Penetration Grade Bitumen 200/300
The history of Penetration Grade Bitumen 200/300 can be traced back to the early 20th century when bitumen was first used in road construction. At that time, bitumen was available in a limited range of grades and specifications, and it was typically produced by the crude distillation of petroleum.
In the 1920s, researchers began to develop more sophisticated methods for refining and processing bitumen, which led to the development of a wider range of bitumen grades. One of these new grades was Penetration Grade Bitumen, which was first introduced in the 1930s.
Penetration Grade Bitumen was developed as a way to provide greater consistency and control over the properties of bitumen. This type of bitumen is characterized by its penetration value, which is a measure of its hardness or softness. By specifying a range of penetration values, engineers and contractors could select the appropriate grade of bitumen for a particular application based on the expected temperature and traffic conditions.
Over time, Penetration Grade Bitumen has become one of the most widely used types of bitumen in road construction, asphalt production, and other applications. It is valued for its durability, resistance to weathering, and ability to withstand heavy traffic loads. Today, Penetration Grade Bitumen 200/300 is one of the most commonly used grades of bitumen, particularly in countries with hot climates where the asphalt pavement is subject to high temperatures.
Usages of Penetration Grade Bitumen 200/300
