There are three main types of road rollers: tandem, single-drum and pneumatic. Tandem road rollers have two drums that rotate in opposite directions, while single-drum road rollers have one drum that rotates. The type of drum can vary as well. Some rollers have smooth drums for compacting and smoothing soils. Others have padfoot drums that have blunted "teeth" for compacting softer soils. Each type of road roller has advantages and disadvantages, so it is important to select the right one for the material you're compacting and the job size. To decide which roller is right for your project, check out our Project Uptime article.
