A resin-extended modified diene elastomer is capable of being obtained by a process comprising at least: anionically polymerizing, in an organic solvent, at least one conjugated diene monomer having from 4 to 12 carbon atoms in the presence of a polymerization initiator to form a living diene elastomer having a number-average molar mass Mn1; modifying the living diene elastomer by reaction with a modifying agent to form a modified diene elastomer having a number-average molar mass Mn2 and a glass transition temperature, measured according to the standard ASTM D3418-08, within a range extending from −95° C. to −70° C.; adding at least one plasticizing resin to the organic solvent comprising the modified diene elastomer; and removing the organic solvent to obtain the resin-extended modified diene elastomer. The resin-extended modified diene elastomer has an Mn2/Mn1 ratio of strictly greater than 1.00 and an Mn2 of greater than or equal to 200,000 g/mol.
