Reinforcing mesh // 2539196

FIELD: construction.

SUBSTANCE: invention relates to meshy reinforcing roll materials designed for creation of reinforced layers in various coatings, for instance, road, asphalt, concrete 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 doubled with a gap between each other, making from 0.01 to 0.55 of the bundle width, bundles in the other crossing direction are made as doubled without a gap between each other. Bundles doubled without a gap comprise longer threads stretching in a wave-like manner, forming loops that fix bundles doubled without a gap with bundles doubled with a gap in crossing zones. Width of bundles doubled with a gap makes from 1.3 to 2.5 of width of bundles doubled without a gap. Impregnation and/or coating is arranged by bitumen produced from water emulsion of bitumen.

EFFECT: reduction of possibility of irreversible deformation and damage of a mesh under conditions of considerable deformations of the coating and preservation of reinforcing ability of the mesh even after significant deformations of the coating.
