Bitumen 200/300 refers to a penetration grade of bitumen commonly used in road construction and industrial applications.
What 200/300 Means
The numbers 200–300 indicate the penetration value (measured in 1/10 mm) of a standard needle into the bitumen under specific conditions:
Higher penetration number = softer bitumen
Lower penetration number = harder bitumen
So Bitumen 200/300 is a soft grade.
Typical Characteristics (approx.)
Penetration: 200–300 (0.1 mm)
Softening point: ~35–45°C
Viscosity: Lower than harder grades (e.g., 60/70)
Color: Black or dark brown
Common Uses
Because it is soft and flexible, Bitumen 200/300 is usually used in:
Cold climates (where harder bitumen might crack)
Spray applications
Bitumen emulsions
Industrial uses such as waterproofing, insulation, or roofing felt
Manufacture of cutback bitumen
Comparison With Other Grades
| Grade | Hardness | Typical Climate |
|---|---|---|
| 40/50 | Hard | Hot climates |
| 60/70 | Medium-hard | Moderate climates |
| 80/100 | Medium | Moderate–cold |
| 200/300 | Soft | Cold climates |
Technical specifications for Bitumen 200/300 (penetration grade) based on commonly accepted industry standards (ASTM, AASHTO, and EN/BS where applicable). These values are used for quality control, procurement, and design of pavements, emulsions, and related products:

Penetration (ASTM D5 / EN 1426)
Indicates softness of bitumen.
200–300 means a softer grade, suitable for colder climates or applications requiring flexibility.
Softening Point (ASTM D36 / EN 1427)
Temperature at which bitumen softens enough to let a small steel ball fall a specified distance.
Higher values generally indicate better high-temperature performance.
Ductility (ASTM D113 / EN 13398)
Measures the ability to stretch without breaking useful for low-temperature cracking resistance.
Flash Point (ASTM D92)
Safety parameter for processing and transport — higher flash point means less risk of ignition.
Solubility
Ensures the bitumen is free from excessive non-bituminous materials; indicates purity.
