Because conditions in the field do not match the ideal conditions in a laboratory, the target compaction is scaled to a percentage of the dry density determined in the lab. This can range from 90 percent to over 100 percent.

Is it possible to obtain a relative compaction higher than 100% in the field justify your answer?

Explanation of Solution

The dry unit weight in the field might be more than the dry unit weight obtained in the lab, depending upon the soil type and moisture content. Therefore, the relative compaction can exceed 100%.

What is the higher compaction will result in?

These studies agree that a higher compaction effort increases the dry density and, consequently, the stiffness and strength of the material.
