Typical Engineering Properties of Different Soil Groups Compaction . Soil compaction is the process of mechanically increasing the soil's density by reducing the air void space between its particles. This densification leads to several desirable outcomes, including higher bearing capacity, reduced permeability, and improved stability.

What's the "Curve"? The "curve" referred to in the term is the "bell curve," which is used in statistics to show the normal distribution—what the expected variation is—of any set of data.It's called a bell curve because once the data is plotted on a graph, the line created usually forms the shape of a bell or hill.
