We provide high quality modified,cutback and other types of bitumen.That is in huge demands in the national and international markets.Bitumen,offered by us ,is available in all grades such as 40/50,60/70 and 85/100.
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 is passed through the residue at temperatures of 250-300 degrees Celsius.The above are the typical Penetration of Paving Grades of bitumen.
