Building of the Green Cross
VEOLIA
The yard
With eight roundabouts and six kilometres of shoulder straps, the Green Cross interchange connects the A16 motorway to the Francilienne – RN104. It is one of the most important road nodes in the Val-d的Oise. Open to traffic at the end of 2019, which imagines driving on roads made, in part, of materials alternative ? Because under the roadway, 70,000 tons of NEW.O Grave make up the shape layer. This product comes from the recovery of chewer material, a solid residue of energy recovery of non-hazardous waste.
Technical solutions
Once worked out (clashing, screening, clearing), the severe chewing is a competitive alternative to natural road materials. Performing, he replaces the severe limestone whose extraction in Ile-de-France is scarce. After several months of analysis and testing to verify compliance with market specifications. Results, both in terms of technical behaviour and compliance with standards, allowed its use in a layer of form.
NEW.O Grave contributes to the circular and local economy of civil engineering projects in Ile-de-France. The Veolia (IME) installation maturation and development of NEW.O Grave, in Claye-Souilly, receives by river and road the chewers from the energy development centres of the francilian region.
New.O Grave
These geotechnical properties are identical to those of natural aggregates, which are widely used in roadworks. Competitive and respectful of environmental constraints, she convinced the department that preferred it to an increasingly rare natural grave.
NEW.O Grave serves the circular economy by preserving natural resources.
Technical assets and regulatory compliance in civil engineering
Inert, of size 0/20 mm, the NEW.O Grave chewer grave, marketed by Veolia undergoes up to five times more analysis than the traditional materials used in road works.
This alternative material meets the standard NF EN 13242+A1 of the aggregates for materials treated with hydraulic binders and untreated materials used for civil engineering and pavement construction.
NEW.O Grave is CE2+ certified.
This serious substitution can be implemented in accordance with the requirements of the decree of 18 November 2011 in connection with the realization of works for road use of:
- Type 1: 3 metre pavement underlays maximum height and shoulder with surface layer of a minimum slope of 1 per cent
- Type 2: 3 to 6 metre pavements maximum height, technical embankment up to 6 metres high, padding with covering of natural materials (30 cm) of a minimum slope of 5%.
The guide to the acceptability of alternative materials in road technology (Sétra, March 2011) and the application guides identify and frame the reference methodology for the recovery of severe chewers.
