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 (desi millimeters). 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, jumbo bags or other appropriate containers for transport and storage.
