Try these first

1. 1.

   List two types of soils and their compaction methods.

   Hint

   Consider common types used in construction.

2. 2.

   What is the Optimum Moisture Content?

   Hint

   Think about when soil is easiest to compact.

3. 3.

   What type of soils compact easily with vibratory equipment?

   • Cohesive
   • Granular
   • Clay

   Hint

   Think about the characteristics of sand and gravel.

4. 4.

   True or False: Cohesive soils are best compacted using vibratory rollers.

   • True
   • False

   Hint

   Reflect on how clay behaves compared to gravel.

5. 5.

   Evaluate the effects of insufficient compaction in a construction project on granular and cohesive soils.

   Hint

   Think about how poor compaction manifests over time.

6. 6.

   Propose a strategy for achieving optimal moisture levels in asphalt pavement installation over different soil types.

   Hint

   Consider the specifics of each soil type and the desired outcome.
