Description:
Bitumen 60/70 is a penetration-grade bitumen commonly used in road construction and industrial applications. It is a semi-solid form of petroleum-based hydrocarbon material, characterized by its hardness and viscosity. The numbers 60/70 refer to the penetration value, which indicates the hardness of the bitumen. In this grade, the bitumen has a penetration range of 60 to 70 decimillimeters (1/10th of a millimeter) at 25°C, measured by a standard needle under specific conditions.
Uses:
- Road Construction: Primarily used as a binder in asphalt for paving roads, highways, and airport runways.
- Waterproofing: Applied in roofing and damp-proofing to prevent water infiltration.
- Industrial Applications: Used in the manufacturing of bituminous paints, adhesives, and sealants.
- Crack Filling: Utilized for filling cracks and joints in pavements and structures.
Packing & Shipping:
- Bitumen 60/70 is typically packed in steel drums, polybags, or bulk shipments.
- Drums are usually 150-180 kg, while bulk shipments are transported in heated bitumen tankers to maintain liquidity.
- Proper safety measures are followed during transportation to prevent spills and ensure compliance with international shipping regulations.
