12.6. Moisture Susceptibility of Bituminous Mixes

Try these first

1. 1.

   What is 'stripping' in the context of bituminous mixes?

   Hint

   Think about how water affects glue.

2. 2.

   Name one moisture sensitivity test.

   Hint

   It measures something about strength after water exposure.

3. 3.

   What does moisture damage lead to in bituminous mixes?

   • Increased strength
   • Stripping
   • Reduced flexibility

   Hint

   Focus on the effects of water.

4. 4.

   T/F: The Tensile Strength Ratio helps assess moisture susceptibility.

   • True
   • False

   Hint

   Think about strength post-water.

5. 5.

   Design an asphalt mix for a region that frequently experiences heavy rains. Discuss what strategies you would incorporate to mitigate moisture damage.

   Hint

   Consider the environmental conditions and how they might affect the mix.

6. 6.

   Evaluate the consequences of ignoring moisture testing during road construction projects. Provide a case where such neglect led to significant issues.

   Hint

   Think about long-term impacts versus short-term gains on infrastructure.
