A road roller is a heavy-duty machine that uses vibration and weight to compact the surfaces of roads, bridges, parking lots, and other sites. It can be used to compact various materials, including asphalt, concrete, and gravel. Road rollers make materials more compact, thus improving their strength and durability, while also improving their appearance.
The principle of a road roller is simple: it utilizes weight and vibration to compact the road surface. Road rollers can weigh several tons, allowing them to compress the underlying materials through heavy pressure. Simultaneously, road rollers also accelerate the compaction process through vibration.
Road rollers accomplish their work using two different vibration methods: a vibrating canister and a vibrating wheel. The vibrating canister is a cylindrical metal tank located at the bottom of the road roller and vibrated by a hydraulic system. The vibration generated by the canister makes the material more compact. The vibrating wheel is a metal wheel located at the rear of the road roller and driven by an engine. The vibration of the vibrating wheel makes the material compacted more evenly.
