Abstract

La présente invention a pour objet un procédé de déshydratation d'agrégats d'enrobé présentant une teneur en eau allant de 3% à 6% en poids par rapport au poids total desdits agrégats d'enrobé, caractérisé en ce qu'il comporte une étape de déshydratation des agrégats d'enrobé par séchage par lit fluidisé. L'invention a également pour objet l'utilisation d'agrégats d'enrobé secs, tels qu'obtenus à l'issue du procédé de déshydratation de l'invention, présentant une teneur en eau inférieure ou égale à 1%, dans un procédé de préparation d'enrobés bitumineux recyclés, notamment d'enrobés bitumineux recyclés à fort pourcentage de recyclage, comprenant au moins 40% d'agrégats d'enrobé.
