Description
It is a kind of bitumen, which is provided during the process of oxidation of vacuum bottom (the bitumen Definition: 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.
Applications:
This grade is harder than 85/100 and can withstand higher traffic loads. The main common usage of this product is in road making at temperate regions.
