Abstract:
1. A process for the production of a bituminous composition, comprising: (i) producing a mix of aggregates with a maximum diameter which is non-zero and less than or equal to 30 mm and of an amount less than or equal to 0.8 g per square meter of specific surface developed by the aggregates of at least one cationic polymer in the liquid form having a density of cationic charges greater than or equal to 0.5 meq/g and an intrinsic viscosity from 0.01 to 0.8 dl/g, the intrinsic viscosity being measured at 25° C. in a 3M NaCl solution with a capillary viscometer of the Ubbelhode type, the specific surface (Σ (ii) putting the mix obtained in stage (i) into contact with at least one bituminous binder.
