Advantages of Viscosity Grade Bitumen

  • Viscosity grade bitumen is based on fundamental engineerin7g properties and not on empirical properties. It is a performance based grading system.
  • Viscosity grading system takes into account both low and high temperature susceptibility of bitumen.
  • Viscosity grade bitumen is very easy to handle as viscosity value at two different temperatures is available, which would enable user to measure accurate mixing and compaction temperatures.
  • In order to check the quality of viscosity grade bitumen, we only have to conduct 7 no. of tests. This reduces time and cost of testing.
  • The pavements made from VG bitumen will have better performance, because viscosity value at 1350C gives sufficient idea about mixing and compaction temperature ad as a result pavement life is improved.
  • Pavements constructed using VG bitumen can take higher traffic load with extreme weather condition.
