Samenvatting

The article retraces 5 years of use and progressive re-use of recycled materials in work carried out by SCREG Ile-de-France Normandie - Colas Ile-de-France Normandie and COSSON for Aeroports de Paris at the Roissy Charlesde Gaulle, Orly and Le BOURGET platforms. To carry out work on the airport infrastructures, the first form of re-use was for years the near-systematic re-use, geometry and phasing permitting, of the silt materials from sites with a foundation top and capping layer. The performance levels of lime / cementitious binder treated silts from Roissy or Orly are high and durable. For several years, the COLAS group and its subsidiaries, COLAS Ile de France Normandie, SCREG Ile de France Normandie, COSSON and JOUEN have been carrying out work and providing products within an environmental approach. For work on airport facilities, which have a high material consumption, the COLAS group systematically developed the re-use of the materials inplace and recycled materials: so for cementitious graded aggregates, the level of which rose progressively from 11 % (Verge 26 work site carried out by SCREG Ile de France Normandie in 2003) to 26 % (FEDEX parking areas -production by COSSON and work site by COLAS Ile de France Normandie in 2005) and then 45% (T2G parking areas - production by COSSON and work site by COLAS Ile de France Normandie in 2007).Today if the source of recycled materials is very uniform and well controlled, treated graded aggregates containing 100% crushed concrete can be applied, except for the addition of a grading corrector if necessary.
