9.3.3. Ductility Test (IS: 1208)

Try these first

1. 1.

   What does the ductility test measure?

   Hint

   Think about what happens to bitumen in extreme temperatures.

2. 2.

   At what temperature is the ductility test conducted?

   Hint

   Consider normal room temperature for testing.

3. 3.

   What is measured in the ductility test for bitumen?

   • Hardness
   • Elongation
   • Viscosity

   Hint

   Consider what property relates to stretching.

4. 4.

   True or False: A lower ductility value is favorable for bitumen used in pavements.

   • True
   • False

   Hint

   Reflect on how elasticity affects pavement integrity.

5. 5.

   A sample of bitumen elongates to 30 cm before breaking. If another sample elongates only to 10 cm, explain how these values would affect the choice of bitumen for a flexible pavement.

   Hint

   Consider the stresses that pavements face from temperature and traffic.

6. 6.

   Create a comparative analysis of two bitumen samples with different ductility values and discuss their potential performance in real-world applications.

   Hint

   Focus on how each ductility value affects performance characteristics.
