Repairs to motorway A7

In autumn 2014 and spring 2015, Eurovia’s Romans-sur-Isère division carried out repairs to motorway A7 over a 10-km stretch between Pont-de-l’Isère and Valence Sud, in both traffic directions, for VINCI Autoroutes. All asphalt aggregates used in mix formulations were sourced from the worksite itself using planing operations, and each layer consists of between 20 and 50% of recycled aggregates. The project’s configuration required the involvement of two distinct work methodologies: daytime work shift at two stations (20 days) and nighttime work shift (50 nights) with a strict imperative to restore traffic. Implementation of the porous asphalt layer required up to four pavers working side by side.
