ABSTRACT:
A method of transferring a plurality of road elements includes the steps of arranging a plurality of roller units on each of the road elements substantially centrally of each road element, pivotally connecting end portions of the adjacent road elements with one another, engaging the roller units of the road elements by a guiding element having a channel shape and two ends spaced from one another in a longitudinal direction and in a transverse direction, so that the roller units guidingly move inside the guiding element along the guiding element from one of the ends to the other of the ends and at the same time slightly pivot relative to one another, so that the road elements are transferred from a location at one end of the guiding element to the location at the other end of the guiding element.
