Bitumen 40/50

Bitumen is produced from selected crude oils through a process of fractional distilla­tion. The crude oil is heated to temperatures of between 300 and 350 degrees Celsius and fed into a distillation column allowing the lightest fractions of the crude to separate, through vaporization, from the heavier fractions, which remain liquid.

The higher boiling point fractions are then drawn-off via a heat exchanger and enter a vacuum distillation column. This process produces a “short residue” that is used to manufacture several grades of bitumen. The pressure and temperature conditions within the vacuum process will determine the hardness of the short residue, and as such the grade of bitumen produced. The short residue may be further modified by ‘air blowing’ in which air is passed through the residue at temperatures of 250 - 300 degrees Celsius.

Quality: All Bitumen supplied is of the high­est quality and fully compliant with ASTM and AASHTO, equivalent EN and BS In­ternational Standards and Test Methods. Third Party Inspection (SGS/GEOCHEM) for Quality Testing and Analysis certifica­tion are performed for all the supplies and certified for compliance with product speci­fications and International standards.

Applications: Penetration Grade Bitumen are used in various types of road applica­tion such as hot-mix asphalt (HMA) and surface treatment (single or multiple) for pavement base and surfaces and also some industrial applications. Additional processing of this type of Bitumen yields various grades of Bitumen products.

Penetration Grade Determination:The Penetration Test determines the hardness of Bitumen by measuring the depth (in tenths of a mm) to which a standard, and loaded needle will vertically penetrate in 5 seconds, a sample of Bitumen maintained at a temperature of 25°C. Hence the softer the bitumen, the greater will be its number of penetration units.
