Process for producing two-phase mixes

Process for producing a hot, cold or lukewarm ready-to-use bituminous mix, wherein the process comprises the following successive steps:

• (a) preparing a hot, cold or lukewarm master mix or bituminous mix by mixing some or all of a bituminous binder proportioned in liquid form with some or all of aggregates, and optionally with
• some or all of fines and/or
• some or all of aggregate mix and/or
• some or all of various additives
• so as to obtain a mixture in which the aggregates and any fines and aggregate mix are coated by bitumen,
• (b) storing of the master mix or of the bituminous mix obtained in step (a),
• (c) mixing the master mix or the bituminous mix stored in step (b) with one or more additional formulation components so as to obtain a hot, cold or lukewarm ready-to-use bituminous mix,
• in which step (c) is implemented at a mix production site if the additional formulation component is a thinning agent,
• wherein the additional formulation component(s) of step (c) is (are) chosen from:
• bituminous binder complement and/or the aggregates complement and/or aggregate mix complement, and/or all of the fines or a complement thereof, and/or all of the additives or a complement thereof and/or a mixture thereof,
• wherein the additional formulation components are powder or granular additives.
