ABSTRACT:
Architectural or decorative pavement having thin decorative pavers or "tiles" made of or selected from known materials, from metal and impregnated wood to natural stone to clay or cementitious tiles, are bonded to the upper surface of a sand and cement (and latex, if desired) setting bed before the bed takes its initial set. "Thin" pavers are less than 1/4 inches thick. Stronger materials in these pavers lend themselves to minimum thickness in small to medium sizes. Thin pavers of weaker materials require maximum thickness in large to medium sizes.
The pavers are placed in rows and designs as may be pleasing with adjacent side edges spaced apart and forming gaps all around the perimeter of each paver.
While the bed and bond are both green, vertical cuts are made through and below the gaps and through the bond coat and appreciably into the setting bed all around the whole perimeter of each paver. The setting beds are supported on appropriate bases or other supporting means.
After the paving is cured the cuts in the setting bed create a stress line below which destructive forces exerted on the finished pavement are concentrated to vertical downward extensions of the cuts to the full depth of the bed, and form, in effect, whole, separate, monolithic fractured-out pavement blocks which may suffer bodily displacement while preserving the integrated pavers whole and intact.
The cuts into the setting bed, or the cuts and subjacent cracks, comprise by their numbers and proximity, expansion and control joints.
