A method of producing rubber mixes, including a step of mixing a reinforcing filler, having a surface area of over 220 m2/g and a particle size of less than 0.1 mum, with a cross-linkable, unsaturated-chain polymer base. The mixing step is performed in the aqueous phase, in the presence of a surface-active agent of molecular formula (I) (R1CONR2CHR3COO-)nXn+ (I) where: R1 is an aliphatic group C4-C20 R2 is H or an aliphatic group C1-C8 R3 is H or an aliphatic or aromatic group C1-C8 X is a metal cation n is an integer of 1 to 3.
