Bitumen 40 50, Softening Point 40 To 50 Mm Application: Commercial

The grade is one of the most widely used grades of bitumen, and it is the basic bituminous material. Bitumen 40 50 is specified by the standard test penetration, and softening point test is in the range of 40 to 50 mm on 10, and this is commonly used in paving. These numbers indicate the hardness and average penetration depth of this bitumen. The minimum penetration is 40, and the maximum penetration is 50.

Because 50/40 bitumen has high stability in hot weather, special attention has been paid to improving or constructing roads and sidewalks in tropical areas where the average air temperature is high. Also, the versatility of this product for use in hot mix asphalt has increased the demand for this product and the attempt to buy it. It is bitumen that is obtained by performing oxidation process on vacuum baton (raw material of bitumen production which is taken from the bottom of distillation tower in the vacuum of oil refineries) in bitumen production units so that the degree of permeability (a kind of test for Determine the amount of bitumen) stiffness between 40 and 50.
