Bitumen 40-50
Bitumen 40/50 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 in the Bitumen 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
