摘要

The slab of modular paving for collapsible temporary roads and sites belongs to the field of road construction and can be used in all areas of the national economy as collapsible pavings in the construction of temporary driveways and sites. The modular paving slab for collapsible temporary roads and sites consists of a bearing wood base made of double-sided flooring and framed by a metal frame. The outer sides of the frame have half locking devices made in the form of one or more brackets with coaxial holes. The locking devices are additionally equipped with fasteners in the form of a hinge pin mounted on a metal frame when located in brackets fixed with a cotter pin. The technical result consists in the exclusion of mutual horizontal and vertical displacements of the plates, the quick and safe installation of the plates, the unimpeded dismantling of individual plates and the reliable quality of the coating of the plates. 2 s.p. f-ly, 11 ill.
