Abstract

The system is for use with blocks having a supporting base and an upper traffic surface, the periphery of the latter being formed by a series of arcs of a cylinder alternately convex and concave, the convex arcs being inscribed in circles of different diameters. The concrete is poured into a mould consisting of two concentric components, one with internal convex walls to form the lateral concave surfaces of the blocks, and the other with concave walls to form the convex block surfaces. After filling and compacting one of the components, preferably the one with concave walls, is rotated so as to move these walls behind the convex ones of the other component. The block is then knocked out in the axial direction.
