9.2.2. Viscosity

Try these first

1. 1.

   What is viscosity?

   Hint

   Think about how thick or thin a liquid is.

2. 2.

   How does temperature affect viscosity?

   Hint

   Consider what happens to syrup when heated.

3. 3.

   What is viscosity?

   • A measure of thickness
   • A measure of temperature
   • A measure of volume

   Hint

   Consider the nature of liquids like oil or syrup.

4. 4.

   True or False: Higher temperatures increase the viscosity of bitumen.

   • True
   • False

   Hint

   Think about heating honey compared to cold honey.

5. 5.

   A construction site is experiencing issues with pavement deformation. Discuss how viscosity testing might help diagnose the issue.

   Hint

   Link viscosity to the material's behavior under pressure.

6. 6.

   Consider two different climates: a hot desert and a cold tundra. How would viscosity influence bitumen selection in each region?

   Hint

   Think about how temperature affects material behavior over time.
