Compaction Equipment 101 — The Mechanics of Compacting Soil Through Vibration and Repeated Loading
Compaction equipment applies repeated loading to soil or paving material, reducing voids to raise strength and durability. This article explains the relationship between optimum moisture content and maximum dry density shown by the Proctor test, the design of centrifugal force, amplitude, and frequency produced by a vibratory roller's eccentric weight, and the differing roles of plate compactors and asphalt rollers, alongside current machines from Sakai Heavy Industries and Mikasa Sangyo.
