METHOD TO REPAIR AND CONSTRUCT ARTERIAL HIGHWAYS Russian patent published in 2011 - IPC E01C21/02 

FIELD: construction.

SUBSTANCE: future section of a road is cleaned from roots of trees, the road profile is levelled with potential preservation of natural soil structure, helical anchors are installed, a system of anchors is tightened with reinforcement and mesh reinforcement into a single web. The produced mesh reinforcement is filled with a concrete of low grade with coarse crushed stone filling, rolled with a roller having figured teeth for creation of cellular surface. As soon as the first layer settles, the second layer of concrete is applied, of a high grade with fine crushed stone, rolled with a roller having figured teeth of smaller value to create cellular surface. As soon as the second layer settles, the third layer of concrete is applied, of a very high grade with filling of glass crumbs and/or fine glass granules of irregular shape, rolled with a roller having figured teeth of smaller height to create cellular surface. The second version is also proposed, according to which the upper strengthening layer of the road bed is formed with the help of a burner, which converts sand into a variety of ceramics, which is also rolled with a roller with figured teeth to create cellular surface.

EFFECT: increased operational reliability.
