Bitumen 30/45 – Medium-Hard Penetration Grade Bitumen
Description:
Bitumen 30/45 is a medium-hard penetration grade bitumen with a penetration range of 30 to 45 (0.1 mm at 25°C). It offers a balance between flexibility and durability, making it suitable for moderate to high-traffic road construction and industrial applications. Its higher softening point compared to softer grades ensures better resistance to deformation in warm climates.
Uses:
- Road Construction: Used in asphalt mixtures for highways, urban roads, and airport runways.
- Waterproofing & Roofing: Applied in bituminous membranes, damp-proofing, and sealing.
- Industrial Uses: Manufacturing of mastics, pipe coatings, and corrosion protection layers.
- Pavement Binder: Ideal for regions with moderate temperatures and heavy vehicle loads.
Packing & Shipping:
- Packing:
- Bulk (tankers, railcars)
- New steel drums (180 kg)
- Polyethylene-lined bags (custom sizes)
- Shipping:
- Shipped globally via sea, land, or air
- Compliant with IMCO/IATA/ADR safety regulations
