a heavy vehicle with a large, smooth roller used for flattening and compressing surfaces during road construction
A steamroller is a large machine used in construction to flatten and smooth surfaces, particularly in roadwork. It has heavy, cylindrical rollers that are rolled over the ground to compact materials like soil, gravel, or asphalt, creating a solid and even surface. Steamrollers are often used for paving roads, driveways, or parking lots, and they help make the surface more durable and stable. Though originally powered by steam engines, modern steamrollers are now typically powered by diesel or other engines.
