| Abstract: | Higher grade VG bitumens are prepared particularly by blending of 0.1 to 20 wt % specific Sulfur-Based Polymeric Additives (SBPA) having MW 1,000 to 10,000 Dalton. The prepared higher grade VG bitumens have Kinematic Viscosity of from 200 cSt to 1000 cSt measured at 135°C. from Base bitumen (VG10) at a temperature from 100°C. to 140°C. and stirring in the range of 800 rpm to 1200 rpm for 30 minutes to 90 minutes for improving the properties of bitumens and to make higher grades of Bitumens (VG20, VG30, VG40) for industrial applications. |
