Methods of forming an asphalt shingle waste powder from asphalt shingle waste
Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

asphalt,
wherein the asphalt comprises 1% to 40% by weight of waste asphalt, based on a total weight of the ASW filled coating; and
50% to 70% by weight of a filler material based on the total weight of the ASW filled coating,
wherein the filler material comprises limestone;
wherein the ASW filled coating having:
A) a penetration point of 15 mm to 45 mm as measured according to ASTM D-5;
B) a softening point of 190° F. to 250° F. as measured according to ASTM D-3461; and
granules on the ASW filled coating.
2. The roofing shingle of claim 1 , wherein the asphalt comprises 1% to 30% by weight of the waste asphalt, based on the total weight of the ASW filled coating.
