obtaining a semi-finished product comprising a reinforcement to which a bituminous layer is applied in a step of applying to said reinforcement said bituminous layer in a fluid form, said bituminous layer comprising inert materials; and
annealing said semi-finished product, following said step of applying said bituminous layer to said reinforcement, so as to embed said inert materials in said bituminous layer, while at the same time drying an outer surface of said bituminous layer, and obtaining an outer surface of said bituminous layer which is dry and free from said inert materials.
