Selecting the Right Plate Compactor for the Job

A plate compactor is a key piece of equipment for almost all paving and pavement maintenance jobs. Plate compactors can be used to compact subbase and asphalt. They are also useful in confined areas where a larger roller may not be able reach. This article discusses some of the options that contractors have when selecting a plate compactor. There are three main categories of plate compactors: a single-plate compactor, a reversible plate compactor, and a high performance/heavy-duty plate compactor. The best choice depends on the size and type of the job. Single-plate compactors go in a forward direction only, and are a popular choice for smaller asphalt jobs. Reversible plates can go in both forward and reverse, and some also operate in a hover mode. Reversible and high performance/heavy-duty plate compactors are often used for subbase or deeper depth compaction. Other factors to consider include the material that the plate is made from, plate width and the shape of the base plate. Amplitude, weight, eccentric frequency and centrifugal force should also be considered. Aside from the plate itself, contractors should make sure the plate compactor comes with a water tank. The water helps create a barrier between the hot asphalt and the cold compaction plate, preventing the plate from sticking to the asphalt. Anti-vibration, central-mount and swinging handles can make the plate compactor easier and more comfortable to maneuver. Contractors need to make sure they understand how to operate the compactors and how to maintain them to keep plates in good working condition. Since there are so many options available, contractors should consider the types of jobs the plate compactor will be used on, and make sure their choice has the features and elements will allow them to get the best compaction and smoothest job possible.
