Abstract

L'invention concerne un procédé de traitement de granulats recyclés qui comprend : a) le séchage desdits granulats ; b) l'imprégnation des granulats séchés avec un composé choisi parmi : un agent hydrofuge choisi parmi : un agent hydrofuge à base de résine silicone et éventuellement de silane et/ou de siloxane, et un agent hydrofuge à base de silane et de siloxane ; un silicate de sodium ; une silice colloïdale ; et un alcalin à base de (OH); c) le séchage des granulats imprégnés. L'invention concerne également l'utilisation des granulats obtenus par le procédé susmentionné.The invention relates to a process for treating recycled aggregates which comprises: a) drying said aggregates; b) impregnation of the dried aggregates with a compound chosen from: a water-repellent agent chosen from: a water-repellent agent based on silicone resin and optionally on silane and / or on siloxane, and a water-repellent agent based on silane and siloxane; sodium silicate; a colloidal silica; and an alkali based on (OH); c) drying the impregnated aggregates. The invention also relates to the use of the aggregates obtained by the aforementioned process.
