REINFORCING MESH Russian patent published in 2015 - IPC D04H3/45 

FIELD: construction.

SUBSTANCE: invention relates to meshy reinforcing roll materials designed for creation of reinforced layers in various coatings, for instance, soil, asphalt ones, etc. The reinforcing mesh with cells formed by crossing bundles of threads, fixed by impregnation and/or a coating, where bundles comprise several threads, separate threads are longer compared to other threads of this bundle, and longer threads stretch in a wave-like manner and form loops. Bundles in one of crossing directions are made as tripled with a gap between each other, at the same time each of three tripled bundles is made from two doubled bundles, placed without a gap between each other, bundles in the other crossing direction are made as tripled without a gap between each other, at the same time bundles tripled without a gap comprise longer threads stretching in a wave-like manner, forming loops, fixing bundles in the crossing zones as tripled without a gap, with bundles tripled with a gap. Impregnation and/or coating is arranged by bitumen produced from water emulsion of bitumen. The mesh is made with anisotropy by deformation capacity, where the anisotropy indicatrix is longitudinal to bundles of threads tripled without a gap.

EFFECT: reduction of possible irreversible deformation and damage of a mesh and also preservation of reinforcing ability of the mesh even after significant deformations of the coating.
