23.4.8. Water content test

Try these first

1. 1.

   What is the maximum allowable water content in bitumen?

   Hint

   Think about the standard limits mentioned in the test.

2. 2.

   Why is it crucial to keep water content low in bitumen?

   Hint

   Consider the implications of heating.

3. 3.

   What is the maximum allowable water content in bitumen?

   • 0.1%
   • 0.2%
   • 0.3%

   Hint

   Recall the limit discussed in our test procedures.

4. 4.

   The presence of water in bitumen can lead to what phenomenon when heated?

   • True
   • False

   Hint

   Think about how heating affects moisture.

5. 5.

   Given a bitumen sample weighing 200g, after the Water Content Test, 0.4g of water is measured. Calculate the percentage of water content and discuss its implications for its use in road construction.

   Hint

   Remember to use the formula for percentage.

6. 6.

   You have a bitumen sample that contains 0.25% water. Propose a plan to reduce this water content within safe limits before the application.

   Hint

   Think about methods to remove water effectively.
