Soil Compaction Factor Values Buildingclubinfo
Soil compaction factor of 95% means that the actual density of the soil is 95% of the maximum possible density of the soil (soil determined in the laboratory). This coefficient is determined by the following methods 1. Cutting ring method soil samples are taken from the compacted layer and tested in a soil laboratory in accordance with GOST 5180-2015 Soils.

In other words, the limiting value of the compaction ratio is numerically equal to the expansion factor for loose particles. Compaction Percent. A less common compaction value can be obtained from volume changes. From the example, the maximum compaction from loose chips to solid wood is 10 cubic feet, while the actual compaction is 3 cubic feet.
