Zusammenfassung:	The invention relates to a method for processing recycled aggregates with a particle size that is less than or equal to 4 mm, which method comprises: a) drying said aggregates; b) impregnating the dried aggregates with a compound selected from: a water-repellent agent selected from a water-repellent agent based on silicon resin and optionally on silane and/or siloxane, and a water-repellent agent based on silane and siloxane; a sodium silicate; a colloidal silica; and an alkaline based on (OH"); c) drying the impregnated aggregates. The invention also relates to the use of the aggregates obtained by the aforementioned method. L'invention concerne un procédé de traitement de granulats recyclés de granulométrie inférieure ou égale à 4 mm, 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.
