Group of answer choices

Sheepsfoot

Multi-tired Pneumatic Roller

Smooth Steel Drums

Tamping Foot

part 2)

Group of answer choices

True

False

Answer 1

Answer:

Part 1

The equipment that are generally better to compact pure sand are multi-tired pneumatic roller and smooth steel drum rollers.

Whereas sheepfoot and tamping foot rollers are best suited for cohesive soils like clay.

Part 2

True

Yes it is possible to estimate the wet density at optimum moisture from the optimum moisture content from the formula:

And the moisture content and dry density can be obtained from the optimum moisture content graph.
