Bitumen 40/50

Bitumen 40/50

The main common usage of this product is to use in road making at tropical regions.

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 40-50.
