NOVELTY - Method involves (i) obtaining asphalt shingle waste (ASW); where the ASW comprises asphalt, limestone powder, granules, and impurities; performing sufficient grinding steps and screening steps on the ASW to result in an ASW powder having an average particle size of 2-425 microns, where the ASW powder comprises 5-40 wt.% asphalt based on a total weight of the ASW powder, 60-95 wt.% limestone powder, granules, and impurities based on the total weight of the ASW powder; combining the ASW powder with at least one process oil and at least one polymer, so as to form an adhesive composition, where the adhesive composition comprises 10-60 wt.% ASW powder based on a total weight of the adhesive composition; 20-70 wt.% at least one process oil based on a total weight of the adhesive composition; and 0.5-30 wt.% at least one polymer based on a total weight of the adhesive composition. USE - The method is useful for forming an adhesive composition from asphalt shingle waste powder. ADVANTAGE - The method adopts improved method of processing ASW and for forming useful products from ASW and ASW powder.
