A variety of rollers on road construction
PNEUMATIC ROLLERS
SEGMENTED PAD ROLLERS
SOIL COMPACTORS
Goat hooves rollers: Goat hooves rollers have a cylinder equipped with a number of protruding legs, and these legs help the hooves, known as hooves, to compaction. A flock of sheep or goats leaves on the ground. This roller performs the compaction action using static pressure and also control. These rollers usually have several cylinders and are used in pairs.
Network rollers: this type of rollers. It can be used at a relatively high speed and does not scatter the soil during operation. These rollers are suitable for crushing lumps of sticky soils. Also, this roller can be used for crushing and compacting soft stones.
Vibrating rollers: Certain types of soil such as sand and coarse stones show a very good reaction to the compaction produced by the combination of pressure and vibration. When the soil vibrates, the particles move closer to their neighboring particles to increase the specific weight of the mass. >Vibrating rollers are available in different sizes, from small manual rollers with vibrating metal plates to large car rollers that have smooth cylinders or goat legs or shoes. Pounding the soil also reduces some of the moisture in the soil, which is considered an advantage in the case of wet soil compaction. The compaction force of vibrating rollers is basically caused by the vibration and static weight of the roller.
Smooth steel wheel rollers: this type Rollers are still widely used in construction operations. These rollers are used to compact the asphalt surface of roads.
Pneumatic rollers (rubber wheel): these rollers are flat and the rules of applying pressure on subsurface soil compaction are true for them. Some of these rollers are self-propelled and others may be pulled by other machines. Pneumatic rollers are the main type of multi-wheel roller. Heavy pneumatic rollers are available. Heavy pneumatic rollers are used for compacting thick layers of soil. Multi-wheel rollers are used for finishing works and asphalt surfaces and embankment of dams.
Rollers with steel plates (with shoes): this type The rollers are similar to the goat foot rollers and instead of the goat foot legs, relatively larger steel plates are mounted on the roller cylinder. These types of rollers cause less disturbance on the soil surface during compaction.
