highway engineering. SUBSTANCE: inventorial development road is used in laying of temporary roads on sands and loose watered grounds including those constructed on swamps and serving as bases of permanent roads. Road consists of interconnected detachable sections. Each section of assembled from separate transverse to road longitudinal axis, round in cross-section members interconnected by longitudinal flexible connections with possibility of their rolling and unrolling. Novelty consists in that transverse members are metal tubular, mainly, from usable casing pipes and located over length of section at distance from one another amounting is axes of (0.014-0.018)L, where is section length. Each flexible connection is located on section side facing ground, fixed to each tubular member, and has connecting loops protruding beyond section ends. It this case, passed into loops of all flexible adjacent sections is tubular connecting member. Technical result of the invention consists in improvement of temporary work under conditions of sandy and loose watered grounds, including of swamps with reduction of labor input and material consumption in road preparation and laying. EFFECT: improved design. 8 cl, 5 dwg
