Smooth-wheeled rollers
Vibratory rollers
Sheep foot rollers
Tampers
Answer is Right!
Answer is Wrong!
The correct answer is C. Sheep foot rollers.
Sheep foot rollers are the most suitable type of equipment for compaction of cohesive soils because they have a large surface area that can apply a large amount of pressure to the soil. This helps to break down the soil and create a dense, compacted surface.
Smooth-wheeled rollers are not as effective for compacting cohesive soils because they have a smaller surface area and do not apply as much pressure. Vibratory rollers can be used to compact cohesive soils, but they are not as effective as sheep foot rollers. Tampers are only effective for compacting small areas of soil.
Here is a more detailed explanation of each option:
- Smooth-wheeled rollers have a smooth surface that rolls over the soil. This type of roller is not very effective for compacting cohesive soils because it does not apply enough pressure to break down the soil.
- Vibratory rollers have a vibrating surface that helps to break down the soil and create a dense, compacted surface. This type of roller can be used to compact cohesive soils, but it is not as effective as sheep foot rollers.
- Sheep foot rollers have a large surface area with projections that resemble sheep’s feet. These projections apply a large amount of pressure to the soil, which helps to break down the soil and create a dense, compacted surface. Sheep foot rollers are the most effective type of equipment for compacting cohesive soils.
- Tampers are small, handheld devices that are used to compact soil. They are not very effective for compacting large areas of soil, but they can be used to compact small areas of soil, such as around the foundation of a building.
