Bitumen 60/70 is a standard Penetration Grade of Bitumen ASTM D946M, typically used as a Paving Grade
Bitumen suitable for road construction and for the production of asphalt pavements with superior properties
particularly in road and airport constructions and other similar applications. This grade of Bitumen is mainly
used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grades of Bitumen is
produced from Vacuum Residue, which is blown by hot air in the Biturox Blowing Unit; The fully automated
process runs continuously resulting in a constant and homogeneous finished product quality. Wataniya’s
Penetration Grade Bitumen can be supplied in any grade and are designated by two numbers to indicate the
mid-points of their penetration ranges.
Bitumen is commonly packed in new 220 Kg barrels and Jumbo Bags.
