The invention relates to a method for producing a mortar containing bituminous binder at a low temperature of aggregate and said bituminous binder. The inventive method is characterised in that an additive exhibiting a high desorption power (in particular zeolite is introduced in the form of granules). The mortar which contains bituminous binder and is producible by the inventive method and a device for producing the mortar containing bituminous binder are also disclosed. La présente invention concerne un procédé de préparation d'un mélange de construction comprenant un liant bitumineux, la température de mélange des granulats et du liant bitumineux étant abaissée. Le procédé est caractérisé en ce qu'un additif ayant un haut pouvoir de désorption (notamment une zéolithe) est introduit sous forme de granulés. L'invention concerne également un mélange de construction comprenant un liant bitumineux susceptible d'être obtenu par le procédé selon la présente invention ainsi qu'un dispositif pour la fabrication d'un mélange de construction comprenant un liant bitumineux.
