A rubber composition based on at least an elastomer matrix is provided. The elastomer matrix comprises a first diene elastomer having a number-average molecular weight, Mn, of greater than or equal to 100 000 g/mol; a functionalized second diene elastomer bearing at the chain end a function capable of reacting with the surface of silica, said functionalized diene elastomer having a number-average molecular weight, Mn, of less than or equal to 80 000 g/mol: and a reinforcing inorganic filler, in an amount ranging from 55 phr to 200 phr. The elastomeric matrix allows good dispersion of the reinforcing inorganic filler. A finished or semi-finished article comprising such a composition, tire tread comprising such a composition, and a tire or semi-finished product comprising such a composition is also provided.
