By applying combined static and dynamic forces to increase the load-bearing capacity of the surface, a vibratory roller is one of the types of a compactor.
It has a drum to densify soil, asphalt, or other materials. The process of densification is carried by transferring vibrations to the surface. The wheel of the vibratory rollers can fully cover the area underneath them.
This type of roller is more efficient than the other types of roller for compaction purposes. A vibratory roller usually has a two-wheel installed on the rear end while a drum roller is installed on the front end.
Vibratory
rollers produce vibrations by filling the drum with basalt. As the drum
rotates so does the basalt. The basalt collides with the walls of the
drum and produces vibrations. The magnitudes of these vibrations can be
increased by increasing the weight of basalt.Alternatively,
the vibration of the vibratory road roller is also obtained through
weights which ar are attached to the shaft inside the motor. The motor
itself is located inside the drum.
