Why 95% Compaction

 · So use of a percent compaction will result in different densities (and therefore different engineering properties) depending on the compaction control test used. For achieving different engineering properties including those mentioned in my earlier posting and that of Focht3, both the molding moisture content and the resulting density are the important factors.

Compaction of Soil

 · Other purposes of soil compaction are: Compaction of soil increases the shear strength and load bearing capacity of the soil. Compaction reduces the voids ratio making it more difficult for water to flow through (water seepage) soil. This is important if the soil is being used to retain water such as would be required for an earth dam.
