Three-wheeled rollers are static rollers, which do not have vibration function and completely rely on their own weight to compact the road surface. Therefore, they are generally relatively large and are large-scale equipment used to compact the roadbed or base layer. This type of large-scale road roller has only one form of car type, not a hand-held type.
Two-wheel rollers are generally vibration rollers. Among them, there are ride-on rollers and walk-behind rollers. Due to the vibration function of this type of roller, the tonnage is relatively small and belongs to the scope of small equipment, which is generally referred to as small rollers.
Small road rollers are mainly used to compact asphalt concrete and other oil surfaces. They have vibrations. Each of the two wheels has a water tank. Water can be sprayed on the wheels to prevent the asphalt concrete from sticking to the wheels for a long time during the compaction process. It is not easy to clean and cause rust and other damage to the equipment.
