the network of modern temporary highways is operated only during logging, and at the end of the work and during the mud season are practically not used. Consequently, there is a need to create collapsible elements for temporary logging roads, which, if necessary, can be assembled in a fairly short time before starting work, is also easy to disassemble after the completion of logging operations and transported and laid in a new place. The coating is a slab containing a wooden multilayer frame made up of elements representing sawmill waste of low-value species, put on a rib or laid flat with gaps, providing a spillage of concrete or polymer mass based on furfural acetone monomer. Untreated wood provides oriented reinforcement along and across the building element, as a result of which its tensile, bending and chipping strength are increased, and bulk density is reduced. The article also considers the constrained swelling of wood filler when using it as a reinforcing element of concrete based on cement is more dangerous, since it is not possible to significantly increase its ultimate extensibility even when introducing latex into its composition. The use of reinforcing mesh is not possible, since the alkali contained in the wet environment of the cement stone destroys the fiberglass mesh.
