A road roller (also called a roller-compactor, or just roller) is a type of vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. In some parts of the world, road rollers are still known as steam rollers, regardless of their method of propulsion. Smaller rollers also exist and are called walk behind rollers, rammers or trench rollers. All of them are currently being used in UAE and Dubai. Used road rollers are listed for sale on Toolsouq.com.
