Bitumen is the end product in the crude distillation process. This raw bitumen is called Straight grade bitumen.
Straight Grade BITUMEN 60/70 / BITUMEN VG-30 (IS:73) is being used in construction and maintenance of roads, allied and airfields constructions, manufacturing of various grades of bitumen Emulsion.
The straight grade bitumen obtained from the refineries is processed in our highly modernized plant through the exothermic reaction, to the relevant time limit to produce the desired Paving Grades as per the specifications.
