One of the Penetration Bitumen grades is 80/100; this grade has a lower ductility than previous grades like 10/20 & 35/50, and has more ductility than grades higher than itself, like 160/220 & 200/300. This grade of bitumen is manufactured thru the vacuum bottom oxidation process.
This product leaves the distillation tower when its penetration is between 80 to 100 desi-millimeters.
This grade of bitumen, 80/100 bitumen, has penetration between 80 to 100 desi-millimeters and softening point between 48 and 56 . Also, it has thermoplastic property means that high temperature led to softer bitumen and low temperature led to harder bitumen.
Primary use of Penetration Bitumen 80/100 is road construction in cold areas. Moreover, it can be used to produce some Emulsion Bitumen, Cutback, and Modified Bitumen grades.
New Steel Drum, Bulk.
It should be mentioned that this grade can be shipped in Jumbo Bag, if the weather is frigid. (Low temperature causes hard bitumen.)
