The ideal choice depends on your project requirements. Double-drum rollers are larger and more powerful. They can smooth large sections of asphalt quickly and easily. Because they don’t have tires, however, they operate best on wide-open, relatively flat surfaces. On the other hand, the pneumatic tires of single-drum rollers offer better maneuverability, traction, and control. They make a great choice for prep work, such as leveling areas for sidewalks, foundations and driveways.
