The invention relates to a rubber composition based on at least one diene elastomer, a reinforcing filler comprising at least carbon black and an inorganic filler with an amount of inorganic filler of less than or equal to 50 parts by weight per hundred parts of elastomer, characterized in that the composition is obtained from a first masterbatch comprising at least one first diene elastomer and carbon black, and exhibiting a dispersion of the carbon black in the elastomeric matrix having a Z score greater than or equal to 90, to which the inorganic filler and at least one second elastomer, identical to or different from the first elastomer, is added, and also to the process for preparing such a composition. |
