14.3.2.2. Boiling Water Test

Try these first

1. 1.

   What does the Boiling Water Test measure?

   Hint

   Think about how aggregate and binder interact with water.

2. 2.

   Why is aggregate stripping a concern?

   Hint

   Consider the impacts of water on the materials.

3. 3.

   What is the primary purpose of the Boiling Water Test?

   • To test tensile strength
   • To evaluate moisture susceptibility
   • To assess temperature resistance

   Hint

   Think about what conditions this test simulates.

4. 4.

   True or False: The Boiling Water Test only measures the strength of the bituminous binder.

   • True
   • False

   Hint

   Consider the interaction between binder and aggregates.

5. 5.

   Design an experiment to analyze the moisture susceptibility of a new asphalt mix using the Boiling Water Test. What variables would you consider and why?

   Hint

   Think about how you would ensure accurate and repeatable results.

6. 6.

   You notice high aggregate stripping in your Boiling Water Test. Identify specific modifications in material selection or design that could enhance moisture resistance.

   Hint

   Consider how each factor contributes to aggregate adhesion.
