WebThe grading of bitumen through penetration test at 25°C was first adopted in 1961 by Bureau of Indian Standards and IS:73-1961 is the first Indian standard on Paving Bitumen, which was in practice until 1991. This standard recommended five grades of bitumen viz. S-35, S-45, S-65, S-90 and S-200. Webthe macrostructure of bitumen at 180ºC was studied (Figures 1 and 2). The obtained results showed that if a polymer that is insoluble or partially soluble in bitumen is taken, the size of the particles in the mixture depends on the ratio of viscosities and the intensity of mixing. With such a mixture, they are emulsified at high
