Abstract

Pneumatique (1) de génie civil comprenant une première couche de travail d’une largeur L1 comprenant des renforts métalliques, d’angle A1, des deuxième et troisième couches de travail de largeurs L2 et L3, comprenant sur des largeurs L21 et L31, centrées, des renforts métalliques, d’angles A12 et A13, et comprenant, de part et d’autre du plan médian, axialement à l’extérieur de L21 et L23, des seconds renforts métalliques élastiques, d’angles A22 et A23 inférieurs à 8°. Le pneumatique comprend deux couches de protection (31), les plus radialement extérieures, de largeurs axiales LPN1 et LPN2 comprenant des renforts élastique et d’angles APN1 et APN2. Les valeurs absolues des angles A1, A21, A31, APN1, APN2 sont supérieurs à 20°. A1 et A31 sont de mêmes signes et de signe opposé à l’angle A21. La largeur L1 est supérieure aux largeurs L2 et L3, et inférieure à une des largeurs LPN1, LPN2. Figure d’abrégé : figure 1
