11.2. Bituminous Emulsions

Try these first

1. 1.

   What is a bituminous emulsion?

   Hint

   Think about what properties of bitumen and water allow them to coexist.

2. 2.

   Name one component of a bituminous emulsion.

   Hint

   How many components are essential for an emulsion?

3. 3.

   What is a key component of a bituminous emulsion?

   • Sand
   • Bitumen
   • Concrete

   Hint

   Think about what gives the emulsion its binding properties.

4. 4.

   Bituminous emulsions can only be used in dry conditions.

   • True
   • False

   Hint

   Recall the benefits of using emulsions in different weather.

5. 5.

   Design a bituminous emulsion suitable for a cold-weather road maintenance application. What factors would you consider in your design?

   Hint

   Ask yourself what conditions the emulsion will face and how to enhance its performance.

6. 6.

   Evaluate the impact of storage stability on the performance of bituminous emulsions in road applications. What measures can be taken to ensure stability while in storage?

   Hint

   Think about how emulsions can change over time and what storage conditions affect them.
