L’op\u00e9ration de liaison de la RD 820 – RD 959 s’inscrit dans le cadre de l’am\u00e9nagement de la nouvelle voie Boulevard Urbain Ouest (BUO) de Montauban. Ces am\u00e9nagements avaient pour objectifs de r\u00e9duire le trafic dans son centre historique et cr\u00e9er des voies d\u2019acc\u00e8s plus pratiques vers les communes \u00e0 l\u2019ouest de la ville. Le tron\u00e7on 1C comportait 3 ouvrages de franchissement et 2 murs de sout\u00e8nement. Les travaux consistaient \u00e0 r\u00e9aliser l’ouvrage d’art le plus important destin\u00e9 au franchissement de la voie ferr\u00e9e Paris-Orl\u00e9ans-Limoges-Toulouse par le BUO. L’ouvrage pr\u00e9sente une longueur totale de 91m. La plateforme du BUO est un sout\u00e8nement en remblai d’environ 5m de hauteur de type remblai renforc\u00e9 parement min\u00e9ral. Les mat\u00e9riaux de remblais utilis\u00e9s pour r\u00e9aliser le massif sont de type Argile A2 trait\u00e9s (issus du site).<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

France Maccaferri a propos\u00e9 son principe en remblai renforc\u00e9 parement min\u00e9ral, le Terramesh Min\u00e9ral, qui associe esth\u00e9tisme et technicit\u00e9. Il est parfaitement adapt\u00e9 pour r\u00e9aliser ce type d’ouvrage d’une hauteur importante en acceptant de fortes sollicitations. Les structures Terramesh Min\u00e9ral sont constitu\u00e9es d\u2019une nappe de renfort en grillage m\u00e9tallique double torsion plac\u00e9e \u00e0 l\u2019horizontale dans le remblai et effectuant un retour au parement. La fa\u00e7ade est doubl\u00e9e par un panneau de treillis soud\u00e9 maille 50x100mm identique \u00e0 ceux utilis\u00e9s pour les gabions en panneaux \u00e9lectrosoud\u00e9s, permettant ainsi une homog\u00e9n\u00e9it\u00e9 visuelle avec l’habillage en gabion effectu\u00e9 en t\u00eate des cul\u00e9es b\u00e9ton. Le grillage double torsion est rev\u00eatu d’un polym\u00e8re lui permettant de r\u00e9sister \u00e0 l’agressivit\u00e9 chimique des sols trait\u00e9s. Des g\u00e9ogrilles de renforcement \u00e0 hautes performances Paragrid 50, 100 et 200 ont \u00e9t\u00e9 ins\u00e9r\u00e9es dans le remblai en compl\u00e9ment des nappes de grillages double torsion. L\u2019utilisation des mat\u00e9riaux du site pour constituer le remblai pendant la construction a permis une \u00e9conomie et une empreinte carbone limit\u00e9e. L’ouvrage a \u00e9t\u00e9 mis en \u0153uvre par les \u00e9quipes Maccaferri, sous certification Asqual ROG (R\u00e9alisation d’Ouvrages en Gabions).<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
