Question

1.       Compute the compactive effort or compaction energy for a soil sample compacted in a mold with a volume of 1/30 cubic foot which uses 4 layers to place soil in the mold and compacts each layer using a hammer with a weight of 10 lbs that is dropped 12 inches and uses 20 blows per layer.

2.       Using the result from question 1 compare the compaction energy to the Modified Proctor compaction test and the Standard Proctor compaction test?

3.       What does the zero-air-voids line represent?

4.       Estimate the Maximum dry density for a soil having an optimum water content of 14 percent and a specific gravity of 2.65.

5.       Describe the steps used to perform a sand cone density test.
