A roller compactor is a heavy construction machine used to compact soil, asphalt, or gravel. It features large, heavy drums that roll over the surface, applying pressure to reduce air gaps and increase density. This process is essential for creating stable foundations for roads, parking lots, and other structures. These machines come in various types, including static rollers, vibratory rollers, and tandem rollers, each designed for specific tasks. Roller compactors are commonly used in civil engineering projects to ensure that surfaces are solid and durable, which helps prevent future damage and prolongs the lifespan of the construction.
