Summary:Road restraint system (10) comprising a plurality of poles or uprights (11) fixed in the ground and joined together by at least one longitudinal element (12) and anchoring elements (20) of the poles (11) designed to restore system containment and energy absorption performances in the event of impact, wherein said anchoring elements (20) comprise a plate (21) driven into the ground and rotatably mounted at one end of a tie rod (23) whose other end is constrained to a pole (11), such that the tensioning of said tie rod (23) first causes the rotation of the plate (21) until it is perpendicular to the load direction. Système de retenue routier (10) qui comprend une pluralité de poteaux ou de montants (11) fixés dans le sol et reliés ensemble par au moins un élément longitudinal (12) et des éléments d'ancrage (20) des montants (11) conçus pour restaurer les performances de confinement de système et d'absorption d'énergie en cas d'impact. Les éléments d'ancrage (20) comprennent une plaque (21) entraînée dans le sol et montée rotative à une extrémité d'une tige de liaison (23) dont l'autre extrémité est contrainte à un montant (11), de telle sorte que la tension de la tige de liaison (23) provoque d'abord la rotation de la plaque (21) jusqu'à ce qu'elle soit perpendiculaire à la direction de charge.
