It`s 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 which its penetration point (kind of test to indicate the hardness of bitumen) becomes between 85-100.
