Types and Applications

Soil Compactors

COMPACTORTYPES Compaction equipment can be grouped generally into the following classifications: sheepsfoot vibratory pneumatic high speed tamping foot chopper wheels (see Landfill Compactor section)

Combinations of these types are also available, such as a vibrating smooth steel drum. For ease of comparison, the compactors have been placed on the Zones of Application Chart shown below. This chart contains a range of material moistures from 100% clay to 100% sand, plus a rock zone. Each type has been positioned in what is considered to be its most effective and economical zone of application. However, it is not uncommon to find them working out of their zones. Exact positioning of the zones can vary with differing material conditions.
