Claim:
A process for separating constituents of a solid material stream having as constituents at least asphalt and one solid material, comprising the steps of: a) shredding the material in the solid material stream to form a stream of shredded material mass; b) providing a first solvent stream; c) mixing the shredded material stream with the first solvent stream to dissolve the asphalt in the shredded material mass, to form a first slurry stream comprising a solution of asphalt dissolved in the first solvent, and solid materials; c) separating at least some of the solid materials in the first slurry stream from the asphalt and first solvent solution in the first slurry stream to form a final solid materials stream and a final asphalt-solvent solution stream; and d) separating the solvent and the asphalt in the final asphalt-solvent solution stream to form a reclaimed solvent stream and an asphalt stream.
