10.5.4. Viscosity Test

Try these first

1. 1.

   What is viscosity?

   Hint

   Think about how easily liquids move.

2. 2.

   Name a common viscometer used in viscosity testing.

   Hint

   Recall the tools we discussed in class.

3. 3.

   What does viscosity measure?

   • Temperature
   • Flow behavior
   • Pressure

   Hint

   Consider what aspect of liquid movement it relates to.

4. 4.

   True or False: The Brookfield viscometer is used mainly for testing asphalt.

   • True
   • False

   Hint

   Recall the viscometers we talked about in class.

5. 5.

   Design an experiment to compare the viscosity of two different bituminous binders at high temperatures.

   Hint

   Ensure you control variables to maintain accuracy.

6. 6.

   Discuss the implications of high viscosity in bituminous binders when used in hot climates.

   Hint

   Consider the flow requirements during construction at different temperatures.
