Overview
Compactors, also called rollers, are heavy equipment machines used for soil compaction. Compaction takes place on almost every construction project for tasks like densifying fill. Compaction increases soil density due to the expulsion of air through mechanical means. The two types of compaction forces include static force, where the dead weight of the machine applies downward pressure on the soil surface, and vibratory forces, where the compactors create a downward force on the surface.
The most common soil compactors include smooth drum compactors, padfoot compactors, and sheepsfoot compactors.
