Bitumen 70/100 – Premium Grade Petroleum Bitumen
Description:
Bitumen 70/100 is a penetration-grade bitumen classified by its hardness and viscosity, with a penetration range of 70 to 100 (0.1 mm at 25°C). It is a semi-hard bitumen widely used in road construction, waterproofing, and industrial applications due to its optimal balance of durability, flexibility, and adhesion properties.
Uses:
- Road Construction: Asphalt binder for paving roads, highways, and airport runways.
- Waterproofing: Used in roofing membranes, damp-proofing, and pipe coatings.
- Industrial Applications: Manufacturing of bituminous paints, adhesives, and sealants.
- Pavement Repair: Ideal for hot-mix asphalt (HMA) and surface dressing.
Packing & Shipping:
- Packing:
- In steel drums (150–200 kg net weight).
- Polyethylene-lined jumbo bags (1-ton bulk).
- Bitutainers (20-ton isotanks for bulk shipping).
- Shipping:
- Transported by sea, land, or rail in compliance with international safety standards.
- Maintained at 150–180°C during bulk transport to prevent solidification.
