The invention relates to an elastomer matrix comprising - a triblock thermoplastic elastomer which has a central diene elastomer block and two end thermoplastic blocks comprising α-methylstyrene units bonded to the diene elastomer block, - from 2% to 10% by weight, relative to the total weight of the elastomer matrix, of a diblock thermoplastic elastomer which has a diene elastomer block and a thermoplastic block comprising α-methylstyrene units, - more than 10% by weight, relative to the total weight of the elastomer matrix, of a thermoplastic polymer comprising α-methylstyrene units, the content of thermoplastic blocks of the triblock and diblock thermoplastic elastomers being at least 10% by weight relative to the total weight of the triblock and diblock thermoplastic elastomers, the content of thermoplastic chains comprising α-methylstyrene units being at most 55% by weight relative to the total weight of the elastomer matrix, wherein the thermoplastic chains comprising α-methylstyrene units consist of the chains of the thermoplastic polymer comprising α-methylstyrene units and thermoplastic blocks of the triblock and diblock thermoplastic elastomers.
