Title: BEAD OF A TYRE FOR A HEAVY VEHICLE OF CONSTRUCTION The invention relates to improving the endurance of the beads of a radial tyre for a heavy vehicle of construction plant type by reducing the cracking that starts on the axially outer face of the turn-up and spreads through the polymer coating and filler materials. According to the invention, a transition element (28) made of a polymer transition material, is in contact, via its axially inner face, with the polymer coating material of the axially outer face of the turn-up (21b) and, via its axially outer face, with the polymer filler material (26), and the elastic modulus at 10% elongation of the polymer transition material is somewhere between the respective elastic moduluses at 10% elongation of the polymer coating material and of the polymer filler material. 21b 21 a 2 21a AL a 23b a, D A Dmin H 23a d z'lx HAn+400 d 7a H F Y0 Y'
