Abstract
Methods are provided for making asphalt mix composition from mixtures of binder, aggregate, and tailings derived from a solvent froth treatment performed to recover bitumen from mined oil sands. The tailings derived from the solvent froth treatment can be used to replace at least a portion of the small particles in the aggregate used for forming the asphalt mix composition.
