Multiple choice

Two bitumen samples “X” and “Y” have softening points 450C and 600C, respectively. Consider the following statements: I Viscosity of “X” will be higher than that of “Y” at the same temperature II Penetration value of “X” will be lasser than that of “Y” under standard conditions The correct option evaluating the above statements is

  1. Both I and II are True

  2. I is False and II is True

  3. Both I and II are False

  4. I is True and II is False

C Correct answer
Explanation

Bitumen with a higher softening point (Y) is harder and has higher viscosity at a given temperature compared to X. Therefore, X has lower viscosity and higher penetration value than Y.
