26.6. Prepare graphical plots

Try these first

1. 1.

   What is the purpose of preparing graphical plots in Marshall Mix Design?

   Hint

   Think about how graphs help us see data relationships.

2. 2.

   Describe how the plot of binder content versus air voids is expected to behave.

   Hint

   Consider the role of binder in filling voids.

3. 3.

   What does the plot of binder content versus corrected Marshall stability illustrate?

   • Optimal binder amount
   • Air void content
   • Bulk specific gravity

   Hint

   Think about how stability affects mix performance.

4. 4.

   True or False: A higher flow value always indicates a better mix.

   • True
   • False

   Hint

   Consider what flow represents in material behavior.

5. 5.

   Given the stability and flow data for different binder contents, how would you identify the point of optimum performance based on the plotted graphs?

   Hint

   Review the relationships between different properties plotted.

6. 6.

   If a new binder is introduced, describe the steps you would take to validate its effectiveness using graphical analysis.

   Hint

   Think about re-testing with a similar methodology as before.
