    The reconstruction works on Avraire Road are part of a G2 PRO geotechnical mission<\/strong>, following major damage that occurred during Storm Alex in 2020<\/strong>, which triggered a landslide in the municipality of Tende (06)<\/strong>, at the locality of Saint-Dalmas-de-Tende<\/strong>. A detailed study was carried out to identify the causes of instability and to propose appropriate stabilization solutions to ensure the long-term safety of the road and its users.<\/span><\/p>\n

    The affected ground conditions are characterized by a complex geology, consisting of superficial sandy-clayey formations and rock blocks<\/strong>, which are particularly sensitive to variations in water content and erosion processes, thereby increasing the risk of further landslides.<\/span><\/p>\n

    The works include earthworks and reconstruction of the road using reinforced embankments<\/strong>, built directly within the riverbed, as well as the installation of temporary protection measures against rockfall<\/strong> during the construction phase. A permanent stabilization of the slope upstream of the new road<\/strong> is also planned to guarantee long-term stability. The design service life of the structure is estimated at 50 years<\/strong>.<\/span><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    As part of the geotechnical study, Maccaferri provided technical support to the design office<\/strong>, particularly for the design of retaining structures<\/strong>, rockfall protection<\/strong>, and slope stabilization<\/strong>. This collaboration made it possible to define high-performance solutions, such as the Terramesh\u00c2\u00ae Green system<\/strong> and ParaGrid\u00c2\u00ae geogrids<\/strong>, fully aligned with the site\u00e2\u0080\u0099s geotechnical and hydraulic constraints, for the reconstruction of the road using reinforced embankments.<\/span><\/p>\n

    As the Terramesh\u00c2\u00ae Green system is installed directly within the riverbed<\/strong>, the toe of the embankment is protected by rock riprap<\/strong>, which limits scour caused by river erosion. In addition, an RB 100\/UAF rockfall barrier<\/strong> was installed upstream of the new road to provide protection against rockfall events with energies of up to 100 kJ<\/strong>, which may be triggered during heavy rainfall episodes.<\/span><\/p>\n

    Below this rockfall barrier, the slope overlooking the road was stabilized using a soil nailing system combined with a flexible facing<\/strong>, specifically MacArmour\u00c2\u00ae 30\u00c3\u009730 BIO<\/strong>. The reinforced mesh features a ZnAl alloy coating (GalMac\u00c2\u00ae C2)<\/strong> and is factory-coupled with a coconut fiber biomat<\/strong>, reducing slope erosion.<\/span><\/p>\n

    The Terramesh\u00c2\u00ae and MacArmour\u00c2\u00ae solutions<\/strong>, with their polymer (PoliMac\u00c2\u00ae) and ZnAl alloy (GalMac\u00c2\u00ae C2) coatings<\/strong>, fully meet the project requirements, particularly in terms of durability, thereby ensuring long-lasting and reliable protection of the infrastructure<\/strong>.<\/span><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
