FIELD: construction. ^ SUBSTANCE: racetrack coating of specified sports objects contains elastic layer placed on prepared base on which a loose material is distributed. For stability preservation of coating condition elastic layer is executed in a form of spatial cellular design, closed structure cells of which are preliminary strained and filled by a loose material at saving of specified pre-stressing in walls of cellular structure, thus sealed prepared base is preliminary overlapped by flexible panels of nonwoven synthetic material (NSM). Cellular structure of specified design is fixed to its base by flexible panels of NSM. ^ EFFECT: it allows raising of load-carrying capacity of racetracks coatings of hippodromes, arenas and other sports fields; it allows increasing of lifetime and to cut down expenses and time for maintenance of specified platforms. ^ 7 cl, 4 dwg |
