The numbers in the name of the type of bitumen, such as 85-100, are bituminous permeability in the degree of penetration test used to determine bitumen hardness. In this test, a standard needle under the influence of 100 grams penetrates into the bitumen at 25 degrees within 5 seconds. The penetration value is called tens of millimeters of degree of infiltration. The lower the degree of penetration, the bitter is harder, and the number 85 is minimum and the number 100 is the maximum penetration.
