What is vibratory roller?
A vibratory roller is a compactor having a drum used to densify soil, asphalt or other materials through the application of combined static and dynamic forces to increase the load-bearing capacity of the surface. It’s more efficient compared to other road roller types when it comes to compacting.
Why are steamrollers called Steamrollers?
Steamrollers were rollers that flattened roads. Steamrollers were powered by steam, although the term steamroller is still applied to the more modern rollers run by diesel. Steamrollers flattened surfaces due to the mass of the vehicle and the cylindrical like drums, called rolls.
Is the tamping foot roller the same as the sheepsfoot roller?
Like the sheepsfoot roller, it compacts from the bottom to the top of the lift for uniform density and like the steel wheel, it compacts from the top of the lift. The tamping foot roller is capable of high rolling speeds without throwing material because of the design profile of the tamping foot.
What makes a sheep foot roller good for clay soil?
Sheep foot roller done compaction by static weight and kneading of respective layer. This makes tamping roller better suited for clay soils. Contact pressure of sheep foot roller varies from 1200- 7000Kpa. Tamping foot roller consists of four wheels and on each wheel kneading boots/feet are fixed.
What’s the contact pressure of a sheep foot roller?
Contact pressure of sheep foot roller varies from 1200- 7000Kpa. Tamping foot roller consists of four wheels and on each wheel kneading boots/feet are fixed. Tamping roller has more coverage area i.e., about 40- 50%.
What are the disadvantages of using a sheep roller?
The disadvantages of sheep foot rollers are, In wet conditions, the sheep foot roller is used frequently. The layer thickness of the compacting soil should not be less than the minimum of 50mm, which depends on the length of the foot. This is a disadvantage of sheep foot rollers.
