Works to widen the A57 crossing Toulon (south-east France).
Hundreds of maintenance projects are carried out each year to keep the infrastructure in proper working condition. The most significant projects in 2024 involved resurfacing sections of the A10, A11, A28, A85, A19, A81 and A79. In 2024, 93% of asphalt aggregates from work carried out across the network was recovered in a variety of ways, of which 48% was reused on VINCI Autoroutes worksites. The advances made in the road sector have made it possible to regularly increase the percentage of materials reused in situ. As part of a maintenance campaign on the A87N involving 12 km of the Angers ring road between Chemillé and Cholet, all the aggregate extracted from the old road surface, representing 44,000 tonnes of material, went to produce 120,000 tonnes of recycled asphalt using a mobile plant set up near the worksite. The campaign will continue in 2025, moving on to a 22 km stretch of the A87.
VINCI Autoroutes has pledged to shrink the carbon footprint of each project carried out across its network (upstream Scope 3) by an average of 50% by 2030, compared with the 2019 baseline. The company is already halfway to achieving this target, having reduced the footprint by 25% as at end-2024. The measures deployed in collaboration with its contracting partners and public works companies focus in particular on integrating eco-design principles into structures, expanding the use of low-carbon concrete, recycled steel and green energy to power machinery, as well as optimising project methods and material transport.
VINCI Autoroutes’ construction operations also stand out for their considerable socio-economic impact. All projects carried out across its networks in 2024 represented a total of 4.2 million work hours. The larger projects included professional integration programmes for the long-term unemployed, implemented in collaboration with public works companies and local unemployment offices.
