Plate compactors work with a heavy plate on the bottom, which moves rapidly up and down. In combination with rapid impacts, plate weight, and impact forces, the soil underneath is compacted or packed.
Plate compactors work best on granular soils, such as those that contain more sand or gravel. It may be beneficial to add some moisture to the soil before using the plate compactor. It generally takes two to four passes to achieve proper compaction, but the compactor manufacturer or design engineer can provide some advice depending on the situation.
A plate compactor can be used to compact asphalt and sub-base on driveways and parking lots, as well as to repair them. They are useful in tight spaces that a larger roller might not be able to reach. There are a few options available to contractors when it comes to choosing the right plate compactor.
Compactors are categorized into three main categories:
- single-plate compactors
- reversible compactors
- high performance/heavy-duty compactors.
A contractor must decide which of these to use depending on the job’s size and type.
