Circular cobbled surface in pedestrian zones, and the like

摘要

To produce a circular cobbled surface (10), shaped concrete bricks (27) are laid in concentric rings (18). The circular surface is built up from a number of brick sets, shaped by the brick prodn. machine, in the dimensions for each of the rings. The surrounding cobbled surface is formed by bricks to give an uninterrupted surface structured between the cobbled circle and the remainder of the cobbled surface.
