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/Rmin, where Rmin is minimal arch radius in plane.

Method to stack tires and to connect tire stacks with each other

Method involves laying tires one upon another in several layers so that tread tire parts are in close contact with each other; connecting the tires by inserting fastening members in tire interiors. Tires are grouped in the first tire layer and then perforated strips are installed in interior of each tire. Number of strips depends of number of adjacent tires. Perforated strip orifices are spaced apart a distance corresponding to tire layer thickness. Then adjacent tires are pulled together by means of fastening pins having flat non-threaded parts. The pins are located from top and bottom of tire sides. Then next tire layers are laid and connected in the same way to provide stack having necessary height. Spaces defined in tire stacks and between the tires are filled with filler.

Deicing paving and road structure

Deicing grid comprises base having cellular structure and made of non-conductive material and heating members connected to the base and forming electrical circuit connected to power source. Heating members may conduct current and are arranged in each stiffening rib of cellular structure so that heating members and stiffening ribs create thermal grid. Road structure has ground base and deicing paving located on the base. The deicing paving is provided with load-bearing coating of bituminous concrete, concrete and/or asphalt.
