Big road rollers are big machines used for smoothing roads. They are heavy, and they do a great job of flattening surfaces. They're typically seen at construction sites when roads are constructed or repaired. When the big road roller is in operation, and it runs on the soil or asphalt, it compresses the surface to create a sturdy surface for vehicles to travel on.
