Moisture Content And Soil Compaction | Learn Geotech

Adding too much water will cause air voids to be filled with water, limiting how closely soil particles can be pushed together. This is important because we measure soil compaction in terms of dry density, not wet density. That is to say, we want to know how dense the soil will be after we're done with construction and the soil has dried.
