1. A process for the regeneration of exhaust oils, wherein said process for the regeneration of exhaust oils comprises at least one of the following steps: a) passing of the oil to be regenerated into one or more centrifuges, b) storage of the oil, before a treatment, in suitable containers, c) desiloxanation and d) filtering, characterised in that the by-products of one or more of the steps a) to d) are treated, gathered and mixed together with one another and added to a bituminous material exiting from the exhaust oil regeneration plant,
wherein the by-products coming from step a) undergo a decanting step, to reduce the water contents thereof;
wherein, a solid material coming of decanting is mixed with a strongly dehydrating agent; and
wherein the by-products coming from step b) and/or from step c) are mixed directly with one another and with any other possibly treated by-products.
