9 Claims

1. A method of manufacturing an asphalt briquette or pellet made from recycled asphaltic limestone powder, the method comprising:

(a) obtaining recycled asphaltic limestone powder less than about 2380 microns in size with a mean size of less than about 150 microns, wherein the recycled asphaltic limestone powder comprises asphalt in an amount ranging from 10 wt % to 50 wt %, and limestone in an amount ranging from 50 wt % to 90 wt %, wherein the combination of asphalt and limestone make up at least 80 wt % of the recycled asphaltic limestone powder;

(b) forming the recycled asphaltic limestone powder into a disk, wherein the disk ranges in size from 0.5 inches to 5 inches;

(c) densifying the recycled asphaltic limestone powder by applying pressure to the disk, wherein the pressure applied to the disk ranges from 5,000 lbs to 20,000 lbs, resulting in the formation of a briquette or pellet.
