    Le projet du prolongement de la route de la corniche \u00e0 Brazzaville s\u2019inscrit dans un march\u00e9 de construction plus vaste impliquant les am\u00e9nagements urbains des quartiers de Bacongo et de Mak\u00e9l\u00e9k\u00e9l\u00e9. Le prolongement de la route de la Corniche \u00e0 2\u00d72 voies s\u2019effectue sur 5 km environ entre le pont du Djou\u00e9 et la Case de Gaulle. Le trac\u00e9, sur versant, longe le fleuve Congo et n\u00e9cessite la r\u00e9alisation de plusieurs ouvrages de sout\u00e8nement. La solution technique prescrite au march\u00e9 \u00e9tait un mur en L b\u00e9ton matric\u00e9 avec un renforcement du remblai par boudins de g\u00e9otextiles. Maccaferri a propos\u00e9 une variante en remblai renforc\u00e9 \u00e0 parement b\u00e9ton matric\u00e9 Macres\u00ae qui a s\u00e9duit l\u2019entreprise car elle r\u00e9pondait techniquement et esth\u00e9tiquement au march\u00e9 tout en apportant un gain de temps important pour la pose et une \u00e9conomie globale. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Les renforts en g\u00e9obandes Paraweb\u00ae MD45 ont \u00e9t\u00e9 utilis\u00e9s et se sont parfaitement adapt\u00e9s aux remblais en mat\u00e9riaux interm\u00e9diaires (type 3 au sens de la NF EN 14475) utilis\u00e9s. Suivant les hauteurs et les secteurs les bandes ont eu des longueurs variables entre 4 et 11m. En t\u00eate de mur, la pr\u00e9sence d\u2019un caniveau de 1m30 de profondeur \u00e0 2m du parement ne permettait pas le d\u00e9ploiement des bandes sup\u00e9rieures. Les \u00e9cailles de t\u00eate ont donc \u00e9t\u00e9 reli\u00e9es \u00e0 une longrine b\u00e9ton coul\u00e9e parall\u00e8lement au parement par le biais de fers en attente plac\u00e9s lors de la pr\u00e9fabrication. 15 murs pour une surface totale d\u2019environ 6000m\u00b2 et une hauteur maximale de 8m50 ont \u00e9t\u00e9 r\u00e9alis\u00e9s sur 6 secteurs diff\u00e9rents. La solution Macres\u00ae apporte plusieurs avantages : – l\u2019homog\u00e9n\u00e9it\u00e9 et la souplesse de l\u2019ouvrage : le remblai et le parement composent un ensemble homog\u00e8ne, absorbent les tassements sans dommages et se comportent tr\u00e8s bien vis-\u00e0-vis des sollicitations sismiques. – la fiabilit\u00e9 des renforts Paraweb\u00ae polym\u00e8res, insensibles \u00e0 la corrosion et qui ont une dur\u00e9e de vie de 120 ans. – rapidit\u00e9 et simplicit\u00e9 d\u2019ex\u00e9cution – solution \u00e9conomique, gr\u00e2ce \u00e0 une consommation moins importante d\u2019acier et de b\u00e9ton, et de la r\u00e9duction du nombre de transports pour approvisionner le chantier. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
