    Le travail de thèse vise à proposer de nouvelles approches pour formuler et vérifier l'innocuité environnementale de matériaux routiers à base de sédiments de dragage et de curage. Les travaux seront réalisés dans le cadre du partenariat LGCgE - IMT Lille Douai – COLAS – EQIOM et à travers la chaire industrielle ECOSED DIGITAL 4.0 dont le démarrage est prévu en avril 2019. Ils seront déclinés selon deux axes stratégiques : 1) L'amélioration des procédés de stabilisation physico-chimique des sédiments dans la perspective de leur valorisation en technique routière : Cet axe vise le développement de nouveaux procédés de traitements applicables à différentes typologies de sédiments de curage ou de dragage représentatifs des gisements régionaux et nationaux. 2) La vérification de l'innocuité environnementale de matériaux routiers confectionnés à partir de sédiments dans la perspective d'une sortie implicite du statut de déchet des produits finis. Cet axe vise à proposer un modèle prédictif pour le relargage des substances polluantes à l'échelle de l'ouvrage. (French)

    The purpose of the thesis work is to propose new approaches to formulating and verifying the environmental safety of road materials based on dredging and curing sediments. The work will be carried out within the framework of the partnership LGCgE — IMT Lille Douai — COLAS — EQIOM and through the ECOSED DIGITAL 4.0 Industrial Chair, which is scheduled to start in April 2019. They will be divided into two strategic axes: 1) The improvement of the processes of physico-chemical stabilisation of sediments with a view to their recovery in road technology: This axis is aimed at the development of new treatment processes applicable to different types of sediments for scouring or dredging representative of regional and national deposits. 2) Verification of the environmental safety of road materials made from sediments with a view to implicit removal of the waste status of finished products. This axis aims to propose a predictive model for the release of polluting substances at the level of the structure. (English)
