20.5.1. Temperature

Try these first

1. 1.

   What happens to the resilient modulus of asphalt as temperature increases?

   Hint

   Think about the quality of asphalt during a hot day.

2. 2.

   Define curling in the context of concrete pavements.

   Hint

   Consider what happens to a pizza crust when heated unevenly.

3. 3.

   What is the impact of temperature on the resilient modulus of asphalt?

   • Increases
   • Decreases
   • No impact

   Hint

   Think about how asphalt feels under the heat.

4. 4.

   True or False: Curling occurs in asphalt pavements but not in concrete pavements.

   • True
   • False

   Hint

   Recall what curling refers to in concrete.

5. 5.

   Design a pavement that can withstand extreme temperature changes, accounting for differences in material properties between asphalt and concrete.

   Hint

   Focus on layering and materials that accommodate temperature changes.

6. 6.

   Discuss how climate change may exacerbate temperature-induced pavement issues. Provide examples of how this could affect design.

   Hint

   Think about the trends in weather patterns and how they relate to pavement wear and resilience.
