The yard

The project consisted of the 2×3 lanes of the A4 motorway (enlargement with the creation of a third lane in each traffic direction) between the interchanges A4/A31 (Hauconcourt Cross) and A4/A315 (Mey-Vantoux) on a 11 km motorway, in 2 separate continuous sections.

Chief Operating Officer: SANEF

Director: SETEC

Geotechnical AMO: CEBTP

Market specifications: natural materials excluded, by-products from industry or mining are not permitted.

Technical solutions

EUROGRANUCATSon a technical and environmental basis, has proposed alternative steel dairy, approved by the Master of Works and the Office of External Control (AMO geotechnical).

All alternative materials proposed in this market have been characterised from an environmental point of view according to the environmental acceptability guides of alternative materials in road technology. They are all classified in Type 3 use (all uses, coated, covered and not covered), allowing their implementation regardless of their position in the carriageway structure.
