A recyclable waterproofing membrane has a bituminous binder with a recycled bituminous binder (RBB), optionally a fresh polymer and optionally fresh bitumen and a reinforcement. The bituminous binder has a rejuvenator selected from the group consisting of bio-based oils and/or mineral oils, such as plant-based, pine-oil based or vegetable-oil-based. The recycled bituminous binder is obtained by grinding and melting waterproofing membranes with bituminous binder, polymers and a reinforcement.
An object of the instant application is to provide a process of recycling a bituminous product such as a waste bituminous membrane product optionally containing reinforcement layers comprising grinding and melting steps.
A process of recycling a bituminous product or a bituminous membrane product contacting reinforcement layers. Collecting the waste bituminous products and sorting it in a series of waste bituminous product batches. At least one grinding step of each batch in each series forms a fine ground batch. The fine ground batch is introduced into a recycling unit wherein the fine ground batch is heated and melted and collected as a melted product. The melted product is fed into a mixing tank having a predetermined volume containing fresh carrier.
