Proposed is a vibratory roller with at least one tyre (1, 2) having a built-in twin-shaft vibration generator (S), the roller desing making it possible to cause the vibration generator (S) to execute optionally either a circular oscillatory motion or a directional motion with respect to the axis of rotation (28) of the roller tyre (1, 2). The invention achieves this by virtue of the fact that the unbalanced shafts (3, 4) are disposed coaxially with respect to each other and to the axis of rotation (28) of the roller and that they can be coupled to each other in different ways: either to rotate in the same direction or to rotate in opposite directions, it being possible in each case to change the phase relationship of the unbalanced shafts (3, 4) with respect to each other.
