Abstract

Ce produit géotextile ou de construction composite, destiné à renforcer une couche de matériau intégrant un liant hydraulique (béton) ou bitumineux, comprend au moins une grille de renfort (102, 103) tricotée obtenue par la technologie à maille jetée chaîne ou Rachel, et constituée de fils ou câblés mécaniquement résistant selon les directions production et/ou travers. Le produit géotextile ou de construction intègre en outre une ou plusieurs fibres optiques (104) insérées en sens production et/ou en sens travers, lesdites fibres optiques étant solidaires de la grille de renfort au moyen des fils de liage (105) résultant du tricotage de la grille.
