Abstract
This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.
