A rubber composition based on a diene elastomer, a crosslinking system, and a reinforcing filler is provided, as well as a process for obtaining the composition. The composition includes a starch in a proportion of from 10 to 50 phr (parts by weight per hundred parts of elastomer) and an aqueous or water-soluble plasticizer in a proportion of from 3 to 30 phr. The aqueous or water-soluble plasticizer is water or a mixture of water and glycerol, in which the water is predominant by weight in the aqueous or water-soluble plasticizer. The composition can be used for preparing calendered or profiled tyre-related products, such as a tyre tread, for example. |
