Description of Bitumen 60/70
Bitumen penetration grade 60/70 is semi-hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair conjointly for the production of asphalt pavements with below technical specifications. This grade of bitumen is mainly used in the manufacture of hot combine asphalt for bases and wearing courses. Bitumen 60/70 is the most used bitumen grade and basic material for all alternative bituminous products.
Bitumen Penetration Grade 60/70 is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by RAHA GROUP is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by RAHA GROUP is produced from vacuum residue (short residue) feedstock.
