15.5.1. Steps in Mix Design

Try these first

1. 1.

   What is the purpose of material selection in mix design?

   Hint

   Think about what materials are essential for mixing.

2. 2.

   Define volumetric analysis in the Superpave mix design.

   Hint

   What kinds of measurements do we look to analyze in the mixture?

3. 3.

   What is the first step in the Superpave mix design?

   • Material Selection
   • Compaction
   • Volumetric Analysis

   Hint

   What needs to be selected before any mixing occurs?

4. 4.

   Moisture susceptibility testing is important for assessing what aspect of the asphalt mix?

   • True
   • False

   Hint

   Think about environmental factors affecting pavement.

5. 5.

   Design an asphalt mix for a region where temperatures vary significantly from winter to summer. What factors should you consider when selecting the binder?

   Hint

   Pay attention to temperature ranges during your selection.

6. 6.

   Evaluate the consequences of improper compaction during the Superpave mix design. What could happen to the pavement over time?

   Hint

   Consider what happens to loose materials versus well-compacted materials in a structure.
