FIELD: construction. ^ SUBSTANCE: method for erection of motor road includes erection of earth bed or earth bed with laid layer of crushed stone covered with a layer of soil, for instance sand, on which single-rope geogrid is laid, boards are inserted in its cells, having bent loops at the ends, covering geogrid ropes that adjoin at the ends, fixing board in cell. Vertical fixation of boards is done by either bending loops under ropes of cell or pouring gap between boards with mastic, asphalt concrete or cement concrete. Design of motor road provides for the fact that on earth bed or on layer of crushed stone covered by soil, there is a single-rope geogrid and boards arranged, at the same time boards are installed in cells of geogrid, and bent loops protruding at the ends of boards and covering adjacent ropes, are simultaneously engaged with neighboring loops, which limits both vertical and horizontal displacement of boards, and units of geogrid cells are located at the butt joint of cut board corners. ^ EFFECT: improved bearing capacity of motor roads with provision of evenness and durability. ^ 13 cl, 4 dwg |
