1. A resin-extended elastomer, the elastomer of which is a synthetic diene elastomer obtained by solution polymerization with a number-average molar mass of greater than or equal to 200,000 g/mol and the resin of which is a plasticizing hydrocarbon-based resin having a number-average molar mass of between 400 and 2000 g/mol, wherein the synthetic diene elastomer has a 1,2-vinyl butadiene monomer content of 5% to 30% by weight relative to a total weight of a polybutadiene part of the synthetic diene elastomer.
