What is Bitumen 35/50 means

  • The numbers 35/50 indicate the penetration value range (measured in 0.1 mm).
  • It means a standard needle penetrates the bitumen 35 to 50 tenths of a millimeter under specific conditions (25 °C, 100 g load, 5 seconds).
  • Lower penetration is harder bitumen.

Characteristics

  • Harder and stiffer compared to grades like 50/70 or 70/100.
