METHOD FOR ARRANGEMENT OF TILE IN PRECAST PAVEMENT Russian patent published in 2009 - IPC B44C3/12 E01C5/00 

FIELD: construction.

SUBSTANCE: method includes arrangement of generating square or rectangle, area of which is equal to tile area, on its sides tile side facets are arranged with the help of arcs that create protrusions and cavities that correspond to them in shape. Arcs have similar curvature radius and similar length. Relief of opposite facets are arranged with the possibility of their joining to appropriate facets of neighboring tiles, arcs are coupled at the angle of 90° and 180°. Arcs are arranged by quarter of circumference, center of arcs circumference is located either on side of generating square or rectangle, or at the distance of radius inside or outside from it. In three angles of generating square or rectangle one arc is placed, which rests on sides of appropriate angle, with center of circumference of two of them on top of appropriate angle and with center of circumference of the third arc inside generating square or rectangle. On the fourth angle three serially coupled arcs are installed, free ends of which are rested on appropriate sides of this angle. Two arcs have common center of circumference, and center of the third arc circumference is located outside generating square or rectangle at the distance of arc radius from appropriate top, total amount of arcs is arranged as even but not multiple to 4.

EFFECT: higher reliability of pavement and expansion of pavement operational capabilities.
