Abstract
A process for recycling an asphalt-containing waste product, that comprises breaking up an asphalt-containing waste product in a liquid to produce a wet waste product mixture having particles no greater in size than 10 mesh and at least some of which are asphalt-containing particles. Thereafter the wet waste product mixture is directly used to produce a new asphalt product. New asphalt products are produced entirely or partly from the wet waste product mixture.
