Compaction equipment is used to compact soil, including gravel, stones, rock, asphalt, and sand, making it denser and a better foundation for construction. Double drum rollers would be one such type of compaction equipment.
Double drum rollers come with two steel drums: one in the front and one in the back. This does not have any tires, so it’s the drums themselves that move the roller. Because the drums are smooth, they don’t provide a lot of traction and are harder to maneuver. Typically, they weigh between one and two tons and have either diesel or gasoline engines.
The top use of double drum rollers is compacting asphalt. This partially has to do with the lack of tires. Where pneumatic tire rollers are used on sub-grade soil to compact soil down, double drum rollers do better smoothing out newly laid asphalt for roads, paths, parking lots, and playgrounds.
Although double drum rollers are most ideal as road rollers, there are other uses for them. For example, some are vibratory rollers as well, making them useful for compacting the soil sub-base. This double drum vibratory roller is most effective on granular material, such as gravel or sand.
If you have a construction job that is need of any asphalt, whether it’s a commercial project with a parking lot or there’s a section of road that you’ll need to finish, a double drum roller is the best option for smoothing out the ground prior to laying the asphalt and then smoothing out the asphalt after.
For specific purposes, a double drum vibratory roller is the best tool for the job.
