The COFIROUTE company manages some 1,200 km of motorways, in combining the A10, A11, A28, A71, A85 toll roads and the two-level A86 tunnel completing a Paris Region ring-road. As such, maintaining motorway pavements, some of which date back 42 years, is a major concern and vital challenge in ensuring the durability of these road structures.
