A Road roller (sometimes called a roller-compactor) is an engineering vehicle used to compact dirt, gravel, concrete, and asphalt in construction for roads & foundations. Road rollers are also used in landfill compaction.

The roller can be a simple drum with a handle that is operated by hand, and weighs 100 pounds, all the way up to a massive ride-on road roller weighing 21 short tons (44,000 lb or 20 metric tons; the landfill units can weigh 59 short tons or 54 metric tons) and costing more than $150,000 dollars (U.S.).
