10.5.2. Ductility Test

Try these first

1. 1.

   What does the Ductility Test measure?

   Hint

   Think about flexibility.

2. 2.

   Why is flexibility important for bitumen?

   Hint

   Consider the effects of temperature.

3. 3.

   What does the Ductility Test measure?

   • Hardness
   • Flexibility
   • Viscosity

   Hint

   Think about what measures extensibility.

4. 4.

   True or False: High ductility values are not desirable in bitumen.

   • True
   • False

   Hint

   Remember our discussions on bitumen's properties.

5. 5.

   A region experiences extreme temperature fluctuations. Discuss how a binder with low ductility could fail in this environment.

   Hint

   Link temperature effects to flexibility discussed in class.

6. 6.

   If a new binder shows a ductility value of 5 cm in laboratory tests, explain what steps you would recommend to ensure pavement safety in a real world scenario.

   Hint

   Think about the implications of results we've discussed.
