Le plan de relance autoroutier a mis en \u00e9vidence l’augmentation continue du trafic sur l’A10 entre l’A19 et l’A71. Dans ce contexte, l’am\u00e9nagement de l’autoroute A10 au nord d’Orl\u00e9ans avait notamment pour objectif de fluidifier la circulation avec la cr\u00e9ation de nouvelles voies et l’adaptation des bifurcations autorouti\u00e8res. Dans le cadre des ces am\u00e9nagements, des ouvrages de sout\u00e8nements en remblais renforc\u00e9s parement b\u00e9ton et parement min\u00e9ral \u00e9taient n\u00e9cessaires.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Les remblais renforc\u00e9s r\u00e9alis\u00e9s par Maccaferri constituaient les murs en retour des cul\u00e9es C1 et C3 de l\u2019ouvrage PSI986. Ce viaduc permet de relier l\u2019A71 \u00e0 l\u2019A10 par la bretelle Vierzon-Tours en enjambant l\u2019A10 ( Paris-Tours ). Pour chaque cul\u00e9e, 3 murs en MacRes\u00ae ont \u00e9t\u00e9 r\u00e9alis\u00e9s : les 2 murs en rampe et un mur positionn\u00e9 \u00e0 l\u2019arri\u00e8re de la cul\u00e9e porteuse qui ferme le remblai renforc\u00e9 et cr\u00e9e un espace d\u2019inspection sous la cul\u00e9e. Le syst\u00e8me MacRes de Maccaferri est constitu\u00e9 de panneaux en b\u00e9ton pr\u00e9fabriqu\u00e9s dont les dimensions standard sont 1,5 m x 1,5 m pour une \u00e9paisseur minimale de 14 cm. Des renforts g\u00e9osynth\u00e9tiques de type ParaWeb sont connect\u00e9es au parement : ce sont des bandes constitu\u00e9es d\u2019un faisceau de fibres polyester \u00e0 haute t\u00e9nacit\u00e9 contenues dans une gaine en poly\u00e9thyl\u00e8ne. La stabilit\u00e9 du massif est assur\u00e9e par l\u2019interaction entre les bandes de renfort et le remblai structurel mis en place \u00e0 l\u2019arri\u00e8re du parement. Le parement en b\u00e9ton joue uniquement un r\u00f4le esth\u00e9tique et de confinement local du remblai. Dans le prolongement de la bretelle A10 \/A71, France Maccaferri a \u00e9galement particip\u00e9 \u00e0 l\u2019am\u00e9nagement des murs SOUT991 et SOUT992 localis\u00e9s en contrebas du c\u00f4t\u00e9 Ouest de l\u2019A71. La solution de sout\u00e8nement retenue pour ces ouvrages est un remblai renforc\u00e9 \u00e0 parement min\u00e9ral de type Terramesh System. Il s\u2019agit d\u2019un parement min\u00e9ral de type gabion qui se prolonge par une nappe de grillage m\u00e9tallique en arri\u00e8re de 3 m de longueur. L’installation des ouvrages \u00e0 parement b\u00e9ton et min\u00e9ral a \u00e9t\u00e9 r\u00e9alis\u00e9 par les \u00e9quipes de France Maccaferri.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
