Abstract

Pneumatique radial de génie civil comprenant deux couches de travail (51, 52) et deux couches de frettage (41, 42) dont les éléments de renforcement métalliques extensibles, formant, avec la direction circonférentielle (XX’), des angles de valeurs absolues au moins égales à 5° et au plus égales à 16°, chaque élément de renforcement métallique de chaque couche de frettage (41, 42) est extensible, et a un allongement structurel au plus égal à 1% et au moins égal à 0.3% et les rigidités linéiques tangentes des éléments de renforcement de chaque couche de frettage à 1.5% de déformation, étant au moins égal à 75 KN/mm et au plus égal à 160 KN/mm, la largeur axiale de la couche de frettage LF étant également minorée en fonction des pas et de la rigidité linéique des couches de travail.
