HONEYCOMB STRUCTURE OF ROAD BED Russian patent published in 2010 - IPC E01C3/04 

FIELD: construction.

SUBSTANCE: in motor road that comprises road bed structure with roadsides, slopes, longitudinal and transverse trenches arranged in road bed and filled with loose material, longitudinal trenches additionally contain vertical reinforcing elements with frequency of transverse trenches pitch, at the same time longitudinal and transverse trenches are arranged with depth that is more than depth of frost penetration, trenches are filled with discrete reinforcing material, for instance, tree branches straw, etc., are poured for 90%…95% of binding composition depth, for instance, clay-sand one, on top of which continuous horizontal elements are laid, being fixed to each other in crossings of trenches, for instance polypropylene tapes and trenches are topped-up with binding composition, besides horizontal longitudinal and transverse reinforcing elements are fixed with vertical reinforcing elements, and transverse reinforcing elements are stretched, which provides for compression tension in surface layer.

EFFECT: reinforcement of weak foundation, increased strength and bearing capacity of road.
