Detailed Properties of Bitumen 200/300:
- Consistency:
- The penetration grade (200-300) indicates a softer consistency compared to harder grades like 40/50 or 70/100. This flexibility benefits various applications where adaptability to environmental conditions is crucial.
- Chemical Composition:
- Bitumen is composed of a complex mixture of hydrocarbons. Its specific composition can influence its performance characteristics, such as adhesion and durability.
- Density:
- Bitumen usually has a density of about 1.0 to 1.2 g/cm³, which ensures stability in construction applications.
- Thermal Stability:
- This grade maintains its properties over a range of temperatures, making it suitable for hot and cold climates.
- Elasticity and Plasticity:
- Bitumen 200/300 has good elastic properties, allowing it to recover from temporary deformations, which helps maintain pavement integrity under load.
