Soil Compaction

The density (weight per unit of volume) of soil can be increased by many means. The characteristics of the soil itself can be changed to increase its ability to compact, but the availability of suitable materials and the labor involved make this difficult. Most commonly, tamping, vibrating, rolling or other methods are used to artificially densify the soil. One of the primary factors that affect the ability of any of these methods to achieve maximum soil density is moisture. Too much moisture and the soil will bulge, or shift away from the tool being used. Too little moisture also prevents soil compaction. It is important to achieve the optimum moisture content so the the soil will reach maximum density with the least amount of effort. Maximum density can be measured using a number of methods, the first reliable test was the Proctor Compaction Test, but a neutron probe provides a fast, reliable measurement of soil moisture.
