60/70 Grade Bitumen

Product details

The term "60/70 Grade Bitumen" refers to a specific type of bitumen or asphalt binder used in road construction and other applications. Bitumen is a viscous, black, and sticky substance that is a byproduct of crude oil distillation. It is commonly used as a binder in road construction and roofing, as well as in various industrial applications. The numbers "60/70" in "60/70 Grade Bitumen" refer to the penetration grade of the bitumen. Penetration grade is a measure of the hardness or consistency of the bitumen. It is determined by the depth in tenths of a millimeter that a standard needle will penetrate vertically into the bitumen under known conditions of loading, time, and temperature. In the case of 60/70 Grade Bitumen: The "60" represents the penetration in tenths of a millimeter when a standard needle is allowed to penetrate the bitumen under specific test conditions. The "70" represents the penetration in tenths of a millimeter when the test is conducted at a higher temperature. This grading system helps in specifying the appropriate type of bitumen for various climatic and traffic conditions. Lower penetration grades (e.g., 10/20) are used in hot climates, while higher penetration grades (e.g., 200/300) are used in colder climates. 60/70 Grade Bitumen is commonly used in regions with moderate temperatures. It is suitable for road construction and asphalt mixtures in areas where the climate is not extremely hot or cold. The specific grade of bitumen used in a project depends on factors such as the expected temperature range, traffic conditions, and the type of asphalt mix being used.
