In the past, compactors were informally referred to as “steamrollers” because they had steam engines. Today, however, the typical compactor is equipped with a diesel or gasoline engine. Compactors play a wide variety of crucial roles in construction projects. They are used for compacting base materials such as earth or asphalt, and are found working on roads, airport runways, parking lots, and driveways. The types of models differ in their method of compaction and depend on soil types and moisture conditions. Static and pneumatic-tired compactors generate compacting pressure with the weight of the machine while vibratory models’ weighted steel drums gain additional force through vibrating drums: single vibratory models have a drum in the front of the vehicle and tandem models have a second drum in the rear. Some compactors have oscillating drums. Performance of the rollers can be increased by increasing the size/weight of the drum roller.
We use the terms “roller” (asphalt applications) and “compactor” (soil applications) interchangeably. For the first time, we include landfill compactor sales and production estimates in this report as noted later in this report. Sales and production data does not include compactors used in embankment and trench applications or hand-held plate or rammer and tamping compactors and walk-behind compactors.
