Paving bitumen, graded to IS 73
All four viscosity grades, in bulk or drums, from stock at our Mumbai, Karwar and Mangalore terminals.
Spraying applications and surface dressing. Paving in very cold regions.
Paving in cold climates and at high altitude.
Most national and state highway work. Replaces 60/70 penetration grade.
Highly stressed areas: intersections, toll plazas, bus and truck lanes.
IS 73:2013 requirements
Key limits for each grade. Ask our sales desk for a recent test report on the grade you need.

Summary of IS 73:2013, Paving Bitumen – Specification (Bureau of Indian Standards). RTFOT = rolling thin film oven test. The full standard governs; contract specifications take precedence where they differ.

Bulk or drums
Hot, by road tanker
Delivered hot from our port terminals in our own bitumen road tankers, straight into your plant’s storage. Best for hot-mix plants and large highway packages.
For smaller or remote jobs
Drum bitumen for sites without heated storage, smaller works and remote locations. Available from stock.
Cargo parcels
Full and part cargoes from the Gulf for importers and traders.
