A high-modulus rubber composition is based on at least a diene elastomer, a reinforcing filler, from 1 to 45 phr of reinforcing resin, from 1 to 10 phr of sulfur, and from 0.5 to 15 phr of vulcanization accelerator having a vulcanization initiation time, referred to as 't0', of less than 3 minutes, said composition comprising no vulcanization accelerator having a “t0” of greater than or equal to 3 minutes or comprising less than 2 phr thereof.

An elastomeric laminate is provided. The elastomeric laminate comprises a layer A consisting of a diene rubber composition, a layer B comprising a highly unsaturated diene elastomer B, n layers Ci arranged between the layer A and the layer B, n being an integer &#x2265;2, i being an integer ranging from 1 to n, the layer C1 being arranged between the layer A and the layer C2, the layer Cn being arranged between the layer B and the layer Cn&#x2212;1, the layer Ci being arranged between the layer Ci&#x2212;1 and the layer Ci+1 for values of i ranging from 2 to n&#x2212;1 when n&#x3e;2. Such a laminate has good resistance to separation of the layers which constitute it.
