Import Bitumen 70 Grade — Buy in Bulk from Supplier in India

Bitumen 70 Grade is a penetration-grade petroleum bitumen with a penetration value of 60-70 dmm, produced through controlled oxidation of vacuum-bottom residue. This grade retains flexibility at low temperatures while maintaining stability at elevated temperatures, making it suitable for paving and industrial applications. The material is derived from refined crude oil, with a typical softening point range of 45-55°C and a penetration index (PI) between +2 and -2, indicative of its thermosensitive behaviour.

The product is a semi-solid at ambient temperatures, transitioning to a viscous liquid when heated, which facilitates application in road construction and waterproofing. Typical industry specifications for this grade include a flash point above 220°C, a ductility of at least 75 cm at 25°C, and a solubility in trichloroethylene of 99% minimum. Bitumen 70 Grade is chemically stable, water-resistant, and offers durability in harsh environmental conditions, with a standard density of approximately 1.01-1.03 g/cm³ at 25°C.

Primary applications include hot-mix asphalt for roads, runway surfacing, and industrial uses such as roofing felts and pipe coatings. Buyers typically source this grade in bulk, with standard packaging in new steel drums (150-200 kg) or bitutainers for larger shipments. Importers should confirm compliance with ASTM D946 or EN 12591 standards, as well as local road authority specifications, to ensure suitability for intended use.
