As the roller compacts and flattens the surface, it will vibrate. Since soil, asphalt, and concrete have natural empty spaces, they can cause a building to warp and sink, causing damage to the structure. Using a vibratory roller on your construction project can help keep the building's structural integrity.
The rollers which are generally used are tandem type or pneumatic type rollers having capacity of 6-10 tonnes. The wheels of the rollers are kept damp to prevent the adhesion of mix to the wheels of roller.
