PROCÉDÉ DE FABRICATION D'ENROBÉS HYDROCARBONÉS À FROID, ENROBÉS HYDROCARBONÉS À FROID À MANIABILITÉ CONTRÔLÉE ET LEUR UTILISATION POUR LA RÉALISATION DE REVÊTEMENTS ROUTIERS
The present invention relates to a process for producing cold bituminous mixes, comprising the following successive steps: a. in a mixer, coating, at ambient temperature, all of the solid mineral fractions with all of the binder in emulsion, and optionally a portion of fluxing agent, over a time interval T sufficient to observe a coating of the mix; then b. at the end of the time interval T, adding the remaining amount of fluxing agent, over a time interval t, such that the T/t ratio is greater than 2, the other mixing conditions of steps a) and b) being otherwise substantially identical. The present invention also relates to cold bituminous mixes, capable of being obtained by the process according to the invention and the use thereof for the production of wearing courses, the production of emulsion-stabilized gravels or the production of storage-grade mixes.
