1.4. Impact Rollers

Try these first

1. 1.

   What is the primary function of impact rollers?

   Hint

   Think about their impact force.

2. 2.

   Name one type of soil that is suitable for impact rollers.

   Hint

   Consider the type of soil that can compress easily.

3. 3.

   What type of soil is best suited for an impact roller?

   • Clay
   • Sandy
   • Peaty

   Hint

   Consider the soil types we talked about.

4. 4.

   Impact rollers create compaction through which of the following mechanisms?

   • True
   • False

   Hint

   Think about how weight affects dynamics.

5. 5.

   Analyze a site selected for road-building that has both sandy and clay-like soils. Describe how you would approach the compaction task using impact rollers.

   Hint

   Consider the characteristics of the different soils.

6. 6.

   Hypothesize scenarios where compaction fails due to poor soil selection for impact rollers, and propose alternatives.

   Hint

   Reflect on which roller types are effective for varying soils.
