Q: Which of the following test apparatus is used to determine the temperature susceptibility of bitumen?
  • A. Ring and ball apparatus
  • B. Pensky Marten test apparatus
  • C. Penetrometer
  • D. Tar viscometer
Correct Answer: Option D - Tar viscometer is used to determine the temperature susceptibility of bitumen. Penetration Test [IS : 1203 - 1978]– Apparatus- Penetrometer. Object-To determine hardness or softness of bitumen Ring and ball apparatus–Softening point test denotes the temperature at which the bitumen attains a particular degree of softening under the specifications of test. The test is conducted by using Ring and Ball apparatus.
