ABSTRACT:
Prefabricated concrete elements for constructing paths corresponding to a width N or a multiple thereof contain two groups. The first group comprises flat, four-sided slabs for the straight sections of the path, having a dimension corresponding to the normal width N or half said normal width. The second group of prefabricated concrete elements comprise a plurality of sets of flat, sector slabs for the curved sections of the path having different predetermined radius each set consists of sector slabs having a predetermined radius and radii having a dimension corresponding to the normal width.
