Roofing materials with asphalt shingle waste
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.
