A method comprises obtaining a virgin asphalt and obtaining an asphalt shingle waste. The asphalt shingle waste comprises 5 wt. % to 40 wt. % of asphalt based on the total weight of the asphalt shingle waste. The asphalt shingle waste comprises 60 wt. % to 95 wt. % of limestone, granules, and/or impurities based on the total weight of the asphalt shingle waste. The method comprises obtaining a phase modifier. The method comprises mixing the virgin asphalt, the asphalt shingle waste, and the phase modifier to form an asphalt mixture. The phase modifier is present in an amount of 0.25 wt. % to 25 wt. % based on the total weight of the asphalt mixture. The asphalt mixture is configured to be applied to a roof substrate to obtain a roofing shingle.

An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.
