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