HEXAGONAL ROAD PAVING PANEL Russian patent published in 2007 - IPC E01C5/08 

FIELD: construction of or surfaces for roads, sports grounds or the like, particularly pavings made of prefabricated single units.

SUBSTANCE: hexagonal panel has sides provided with alternating upper and lower connection units including members 102, 103 to be overlapped and joint-pins. Panel 100 has central aperture 109 and bead formed along perimeter thereof. Central aperture is used as drainage orifice, is adapted to stabilize panel on ground surface and improves panel storage in stack. Lower panel side is provided with orifices having small depths and large acute angles. Upper surface has antiskid members. Upper members 102 alternately project out of side panel sides beyond bead 101. Lower members 103 are created by bead thickness reduction. Each upper member 102 has connection orifice 105. Each lower member 103 has corresponding profiled vertical connection extensions 106 to be inserted in connection orifices 105 of upper member 102 to provide adjacent panel overlapping. Panels are fixed by means of pressing pins, which may be removed by means of disassembling tool. Edges of road paving assembled of said panels are covered with decorative strips. Panels may be completely produced of polymeric materials, mainly of waste or recycled polymeric materials or may include rubber and body frame. The panels may be laid directly on ground without ground prior base preparation. The panels may be used at temperature of -30°÷+60°C.

EFFECT: increased load-bearing ability and extended temperature range of panel usage.
