Whether you are preparing to compact various types of soils, crushed aggregate, or hot mix asphalt, selecting the right plate compactor for the job cannot be underestimated. There are certain features that all quality compactors should have, and certain compactors that will only work well with particular soil types and job sites.

By value not by price

Considering all variables, including compaction requirements and compaction plate specifications, is essential to achieving the best possible result. A machine can be cheap but not do the job. An expensive machine may have great specifications but be impossible to operate without difficulty. It is best to ensure that the machine chosen is one that can deliver the required compaction value.

Requirements check

Matching the correct plate compactor to the job specifications is a matter of checking the requirements. Determine the soil type and depth of compaction desired, along with site conditions, such as the size and accessibility of the area to be compacted. In urban areas, narrow roads and high traffic areas, it is easier to maneuver and use a lighter single plate compactor.

plate size

The plate that is part of a plate compactor is usually measured in width. The average size of a plate is 15 to 25 inches. Generating around 3,000 pounds of centrifugal force, the compactor’s breadth and weight are as important a measure of value as the plate size. Steel plates, which conduct heat more quickly, are a better choice for compaction of hot asphalt than cast iron. The shape of the base plate is also a consideration as it affects compaction. A curved plate is better.

Driving comfort

The operator handles on the compactor plates are vital to the overall efficiency of the machine. Unless the operator is comfortable doing the job, the job will progress inefficiently. Ensuring that operator handles are fully adjustable and have padded grips is one of the most essential criteria for operator comfort. These handles are also convenient for transporting the compactor from the jobsite to the storage location.

engine types

An important consideration in compactor plates is the type of motor. Especially when working on longer jobs, engine reliability is vital. Some brands have specialized in engines that give high performance in machines such as a compactor. The best include Honda, Subaru, Kohler, Yanmar, and Lombardini. ‘Vibrations per minute’ (VPM) is another factor in choosing the right compactor. Lower eccentric frequencies are better for use in cohesive soils and higher VPMs for granular materials and asphalt.

compaction quality

There are a few additional things to think about when making sure you choose the right compactor, including compaction quality. The overall design of the machine is also vital for easy maintenance and longevity of the machine.
