3.5. Types of Compaction Equipment

Try these first

1. 1.

   What type of roller is best suited for granular soils?

   Hint

   Think about what roller is described as providing static compaction.

2. 2.

   Which roller has lugs and is effective for cohesive soils?

   Hint

   Remember the type of surface that has a lot of clay.

3. 3.

   What type of soil is best compacted with smooth-wheeled rollers?

   • Granular
   • Cohesive
   • Silty

   Hint

   Focus on the soil type most compatible with static compaction.

4. 4.

   True or False: Pneumatic tyred rollers are only effective for granular soils.

   • True
   • False

   Hint

   Consider the versatility of this type of equipment.

5. 5.

   Analyze why smooth-wheeled rollers might be chosen over other types of rollers in a specific project. Give examples of such projects.

   Hint

   Think about the types of surfaces that require smoothness.

6. 6.

   Consider a construction project needing compaction of a variety of soil types. Discuss the strategies you would use in selecting compacting equipment.

   Hint

   Evaluate the properties of both soil types and their responses to different types of equipment.
