COLLAPSIBLE MOTOR ROAD PAVING Russian patent published in 2007 - IPC E01C5/14 E01C9/02 

FIELD: road building, particularly motor road paving made of prefabricated single units.

SUBSTANCE: motor road paving comprises panels with curvilinear edges. The panel edges are non-symmetric with respect to panel axis. The curvilinear edges define arc of circle having radius equal to r=(1.003÷1.01)·c, where c is half of traffic lane width. Circle center is located on panel axis and spaced a distance from panel edge. The distance is equal to a=(r²-0.25b₀)^0.5, where b₀ is distance between road tracks. The curvilinear edges are convex at the first panel end and concave at another panel end. Concave edge is provided with spike. Convex edge has slot extending from convex edge along outer panel side for distance z=c·L/R_min, where R_min is minimal arch radius in plane.

EFFECT: increased traffic capacity and service performance and extended range of collapsible paving components usage.
