Bitumen 60/70

Bitumen 60/70 is a type of bitumen widely used in asphalt and road construction. Its properties and applications are detailed below:

Properties:

  1. Penetration Value: Bitumen 60/70 has a penetration value between 60 and 70 at 25°C. This indicates how soft or hard the bitumen is.
  2. Softening Point: The softening point is the temperature at which bitumen begins to soften, typically between 49-56°C.
  3. Density: It has a density range of 1.01-1.06 g/cm³.
  4. Viscosity: It has high viscosity, which means it remains sticky and elastic even at high temperatures.
  5. Flash Point: Approximately 230°C, indicating the temperature at which it can be safely heated.
  6. Sulfur Content: Low sulfur content makes it less harmful to the environment.

Applications:

  1. Road Construction: Bitumen 60/70 is widely used as a binder in asphalt mixtures. It provides durability and flexibility, especially in high-traffic areas.
  2. Airport Runways: It is used in airport runways and taxiways because of its high load-bearing capacity and wear resistance.
  3. Bridge Decks: Used in the asphalt paving of bridges, as it is resistant to temperature changes and remains flexible.
  4. Parking Lots and Industrial Areas: Provides durability and longevity in parking lots and industrial areas subject to heavy use.
  5. Waterproofing: Used in some waterproofing applications, such as roofs and floor coatings.

Bitumen 60/70 is a durable and flexible material commonly preferred in civil engineering for road and construction projects. It offers a long-lasting and reliable solution for high-performance requirements.
