Q: Which of the following property of bitumen is related to the pensky-Marten test?
  • A. Ductility
  • B. Softening point
  • C. Flash and fire point
  • D. Viscosity
Correct Answer: Option C - Flash and fire point test is conducted on bitumen to know the safe mixing and application temperature values of particular bitumen grade with the help of Pensky-Martens closed tester. • Softening points test is conducted by using Ring and Ball apparatus. • Ductility test on bitumen measures the distance in centimeters to which it elongates before breaking when a briquette specimen of the materials is pulled at a specified speed and at specified temperature.
