Technique for improving the endurance of beads of a radial tire for a heavy vehicle of the civil engineering type, by blocking the cracks that are initiated in the carcass reinforcement upturn end zone and that are propagated in the surrounding polymer materials, causing the deterioration of the bead over time. A binding element (23), having at least two layers of binding including reinforcement elements made of textile material, is in continuous contact with the carcass reinforcement upturn (211) between a first point of contact (A2) on the axially inner face (211a) of carcass reinforcement upturn, corresponding to a first end (I2) of the binding element, and a last point of contact (B2) on the axially outer face (211b) of the carcass reinforcement upturn.
