Influence of Particle Size Distribution
Soil bulk density is commonly used as a measure of soil compaction. From this point of view, therefore, in order to examine the effect of variation in particle-size distribution upon compacted bulk den-sities, the compacted density and void ratio of the silty clay loam alone are required, in addition...

Soil compaction effect on soil physical properties and the
Earlier investigations have indicated that a relatively low pressure (2.5 kg cm-2) on a sandy clay soil raised the density by ca 0.1 g cm-3 for every additional 10% of soil moisture (Vipper, 1979). The highest negative effect on the soil and plants was caused by 6-time compaction.

Introduction to Soil Science
The indirect effects of climate on soil formation are most clearly seen in the relationship of soils to vegetation. Soils containing more than about 15% clay exhibit plasticity - pliability and the capacity of being Soil compaction is defined as the method of mechanically increasing the density of soil.

Construction inspector's | HOW DO WE TEST COMPACTION?
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. The soil took a long time to work up so it could be easily molded. It contained approximately 40-45% clay.
