METHOD FOR CONSTRUCTING REINFORCED CONCRETE ROAD SURFACE FROM REINFORCED CONCRETE SLEEPERS AND REINFORCED CONCRETE ROAD SURFACE FROM REINFORCED CONCRETE SLEEPERS LAID IN THIS WAY (EMBODIMENTS) Russian patent published in 2024 - IPC E01C5/08 

FIELD: road construction.

SUBSTANCE: first method of making a road surface from reinforced concrete sleepers involves making a prepared base on the local surface, then making a loosened layer and laying reinforced concrete sleepers into it. The prepared base is made with a compaction coefficient of at least 0.95, and the loosened layer is made with a loosening coefficient of at least 1.1 and a height of at least 15 cm. Reinforced concrete sleepers are laid so that the bottom of the reinforced concrete sleeper is the surface of the reinforced concrete road surface, and the side of the reinforced concrete sleeper opposite the base is the base of the reinforced concrete sleeper for laying in the loosened layer. The deviation of the surface of the sole of the reinforced concrete sleeper from the horizontal surface is maintained no more than 15 degrees, and the distance between the soles of adjacent reinforced concrete sleepers is maintained no more than 5 cm. Then the laid reinforced concrete sleepers are acted upon vertically downward with a deviation not exceeding 20 degrees from the vertical, with a force of at least 1.5 kgf/cm², but not more than the pressure force withstood by the reinforced concrete sleeper. In the second method of making a road surface, reinforced concrete sleepers are laid in local soil or in a loosened layer so that the bottom of the reinforced concrete sleeper is the surface of the reinforced concrete road surface, and the side of the reinforced concrete sleeper opposite the base is the base of the reinforced concrete sleeper for laying in local soil or loosened layer. The deviation of the surface of the sole of the reinforced concrete sleeper from the horizontal surface is maintained no more than 15 degrees, and the distance between the soles of adjacent reinforced concrete sleepers is maintained no more than 5 cm. Then the laid reinforced concrete sleepers are acted upon vertically downward with a deviation not exceeding 20 degrees from the vertical, with a force of at least 1.5 kgf/cm², but not more than the pressure force withstood by the reinforced concrete sleeper. In the third method of making a road surface in local soil or in a loosened layer, reinforced concrete sleepers are laid so that the bottom of the reinforced concrete sleeper is the surface of the reinforced concrete road surface, and the side of the reinforced concrete sleeper opposite the base is the base of the reinforced concrete sleeper for laying in the local soil or loosened layer. The outer reinforced concrete sleepers are laid with the sole down. The deviation of the surface of the bottom of the reinforced concrete sleeper from the horizontal surface is maintained no more than 15 degrees, and the distance between the sides of adjacent reinforced concrete sleepers, which are the surface of the reinforced concrete road surface, is maintained no more than 5 cm. Then the laid reinforced concrete sleepers are acted upon vertically downwards with a deviation not exceeding 20 degrees from vertical, with a force of at least 1.5 kgf/cm², but not more than the pressure force withstood by the reinforced concrete sleeper.

EFFECT: reduction in the labour intensity of laying sleeper coverings and an increase in its durability.
