bitumen 60/70 specification and test method www.feedar.co

Definition:

It is a kind of bitumen, which is provided during the process of

oxidation of vacuum bottom (the bitumen production feedstock

 that derives from distillation tower residue in vacuum oil refineries)

 at bitumen production units. In a manner that its penetration point

 (kind of test to indicate the hardness of bitumen) becomes between 60/70.
