Soil Compaction Equipment| Concrete Construction Magazine

Different types of soil have different characteristics that affect its maximum density and optimal moisture content. Soils are typically classified by grain size, which is found by passing soil through a series of progressively finer sieves. A well-graded soil features a wide range of particle sizes, with smaller particles that fill in voids between the larger ones. Such soils develop a suitably dense structure when compacted.

Vibro compaction | Keller North America

During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for the decrease in soil volume from the densification process. The vibratory energy reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.
