Abstract: The roof covering the new Montpellier - South of France TGV station is made of a perforated mineral latticework comprising 115 modular and self-supporting elements in precast white UHPFRC known as “palmes” – allowing the strong southern light to be filtered. These perforated double-cambered elements, in line with the long tradition of glazed vaults in reinforced concrete, have a width of 5 cm and span 20 m. This UHPC layer homogenously ensures durability, protection from sun and rain, and provides natural ventilation of the concourse thanks to the joints between the palmes: a watertight cover-structure. The palmes required the development of a UHPFRC new mix, the White Ductal B3 FI 1.75 % and were subject to a procedure of Technical Experimental Evaluation validated by the CSTB. All roofing elements (10,000 m² in total) were prefabricated within 5 months and installed with tight geometrical requirements in only 2 weeks.
