Try these first

1. 1.

   What does PG stand for in asphalt binders?

   Hint

   Think about how the binder is classified.

2. 2.

   Name one piece of equipment used in binder testing.

   Hint

   It tests for rutting and fatigue.

3. 3.

   What does PG stand for in asphalt binders?

   • Performance-Graded
   • Performance-Guided
   • Total Performance

   Hint

   Think about the classification system.

4. 4.

   The Bending Beam Rheometer is used to assess what?

   • True
   • False

   Hint

   Relate it to temperature effects on pavement.

5. 5.

   Evaluate the impact of climate variability in binder selection for a region that experiences extreme temperature fluctuation.

   Hint

   Consider how temperature affects binder performance.

6. 6.

   Design a small study to compare the performance of a PG binder versus a traditional asphalt binder under equivalent conditions.

   Hint

   Think about what aspects of performance to monitor, like rutting and crack formation.
