Heavy vibratory plate compaction of silty sand: A field study
2022.10.1 Heavy vibratory plate compaction is an efficient technique for improvement of granular soils. However, its practical application is limited by insufficient knowledge about the compaction process and the optimum procedure of execution. In this study, compaction tests were conducted in the field with a 40.5-ton heavy vibratory plate compactor.

How to control Compactability of Sand? - THORS eLearning
During mixing, water is absorbed between the clay platelets, clay swells and generates the ability of sand to be compacted. It is developed and controlled in the muller by the addition of water to the clay sand mixture. When expanded sand is compacted inside a confined space, the volume decreases and this is measured by reduction in the length.

2014.11.25 Cohesive (clay), granular (sand) and organic (for planting) are the three basic soil groups, but only two of these—cohesive and granular—are suitable for compaction. Cohesive soils have particles that stick together, while granular soils crumble easily. Each soil type has unique characteristics, from absorbency to compaction difficulty.
