Prediction of compaction
Soil compaction just affects the air volume and has no effect on the water content or the volume of solids. Air voids line: A line showing the dry density-water content relationship for a soil containing a constant percentage of air voids.

Influence of Particle Size Distribution
The theory and experimentation reported are for the purpose of determining the effect of particle size proportions in soils on their maximum bulk densities and other properties affected by compac-tion. Soil bulk density is commonly used as a measure of soil compaction.

Effect of Compaction on Soil Hydraulic Parameters
The results of the measurements of air capacity (AC), available water capacity (AWC), permanent wilting point (PWP) and pore volume (PV) are shown in Table 2 and Figure 3. The PV of all mixtures containing mineral soil are 40% - 50% vol at a compaction level of 85% Proctor density...

The effects of soil compaction
A soil that contains a uniform mixture of sand, silt, and clay, which is called a well-graded soil, will compact to a lower porosity and usually a higher bulk density than a soil There has been relatively little research done on the effect of soil compaction on the yield of processing vegetable crops.

Construction inspector's | HOW DO WE TEST COMPACTION?
Effect of Moisture on Soil. — Friction between particles is high for soil in a dry condition. Second, the density of the compacted layer will have to be checked for density requirement. See section on Density Measurement for how to determine percent compaction.

Soil Mechanics | Effects of Soil Types on Compaction
Effect of Compaction. on Cohesive Soil Properties. Structure of Compacted Clays. •For a given compactive effort and dry density, the soil tends to be more flocculated (random) for compaction on the dry side as compared on the wet side.

Introduction to Laboratory Testing
Generally applicable to fine-grained soils. Limited to soils containing less than 10% passing No. 200 sieve size. Compaction characteristics are determined by moisture density testing; structural and supporting capabilities are evaluated by appropriate tests on samples of compacted soil.
