Types of Bitumen \u2013 Penetration Grades<\/strong><\/p>\n

Production of different grades of penetration bitumen is achieved by adjusting the air-blowing rate, taking into account feedstock parameters such as temperature and viscosity. Lower air-blowing rates yield bitumen with higher penetration values. <\/p>\n

Performance Grade Bitumen (PG Bitumen)<\/strong><\/p>\n

Production of 13 unmodified PG-grade bitumens (without additives) based on Superpave classification system, out of 33 general grades, and 10 grades from 13 regional climate-specific PG grades available in the country.<\/p>\n

Cutback Bitumen (Back Cut)<\/strong><\/p>\n

Production by blending penetration-grade bitumen (e.g. 60\/70) at 180\u2013190\u00b0C with petroleum-based solvents such as white oil, diesel, or gasoline at 160\u2013170\u00b0C, using either stirred tanks or continuous in-line blending, followed by storage at 60\u00b0C. The blend ratio is adjusted based on the desired cutback grade. Application: Tack coats between asphalt layers or prime coats before asphalt laying.<\/p>\n

Bitumen Emulsion (Green Bitumen)<\/strong><\/p>\n

Manufactured by blending an aqueous phase (water, acid, emulsifier, salt) at 40\u00b0C with hot bitumen (135\u2013145\u00b0C) using a high-shear colloid mill. Stored at 70\u00b0C.Applications: Base bonding, rapid surface sealing, cold mix asphalt, and mulching. Preferred alternative to cutbacks for environmental and cost benefits.<\/p>\n

Polymer Modified Bitumen (PMB)<\/strong><\/p>\n

Designed to withstand high thermal and mechanical stresses. PMBs exhibit superior elasticity, resistance to cracking, deformation (rutting), and fatigue. Suitable for demanding applications. Covers extended PG ranges, e.g., PG 76-22, PG 82-10. <\/p>\n

Oxidized \/ Blown Bitumen (Special Grades)<\/strong><\/p>\n

Produced via air-blowing under controlled conditions to reduce penetration and increase softening point. Example: Grade 10\/90 (penetration: 10, softening point: 90\u00b0C). Produced in batch reactors due to extended residence time.Used in industrial insulation and roofing. Low-volume specialty product.<\/p>\n

 <\/p>\n

Natural Bitumen (Gilsonite \/ Mineral Bitumen)<\/strong><\/p>\n

Gilsonite is a naturally occurring asphaltite found in regions like Kermanshah (Gilan-e-Gharb). It is used in asphalt modification, printing inks, paints, drilling fluids, and adhesives. For asphalt, low-ash grades are preferred.Widely used in China for ink production. <\/p>\n","protected":false},"excerpt":{"rendered":"
