Abstract: A system (10) for recycling asphalt shingle scrap. There is a cold process, hot process, and a separation process. In the hot process, all of the components are ground except for the course surface granules. In the cold process, a type of grind is formed that is the same as the hot process except it is a dry powder. A horizontal mixer (20) can be used either hot or cold. The hot process and cold process can be run in combination with one another or independently. The component separation process uses a screen or the like (34) to separate the cold process material into surface granules, filled asphalt coating, and saturated felt component, while a magnet (38) may be used to help separate nails and other metal objects from the mixture.

Abstract: An asphalt roofing material recycling system and method is used to recycle new and used (post consumer) asphalt materials, such as asphalt shingles, rolled roofing and tar paper that may include granules, fibers or other particles. The asphalt material, which may be in bundles, is broken up and separated and then provided to a cooled recycling vessel. Dry ice is added along with the asphalt material to be recycled. The dry ice removes any moisture present and super-cools the material making it brittle and easier to chip and break up. The recycle vessel includes a number of high speed shippers having tulip hear chipping teeth as well as one horizontal mixer element which stirs the material and makes sure all material is ground. The resulting course to fine powder can be separated by screening and stored as power or compressed into bricks or briquettes.

Abstract: An asphalt roofing material recycling system and method is used to recycle new and used asphalt materials. The asphalt material is broken up and separated. Dry ice may be added to the recycler and/or a jacket coolant used to cool the recycling vessel. The recycle vessel includes a number of high speed choppers having a blunt end as well as a horizontal mixer element with paddles. The recycled asphalt material is provided to a screener that may feature a plurality of sloping levels, each level including a tray below a screen and balls located within the tray that bounce due to vibration to prevent clogging of the screener. A second processing trip involving gravity feeding the material to be further recycled into a cutter with knife edges to further break down the size of the asphalt material is used for large particles that do not pass through the screener.

Abstract: An asphalt paving mixtures suitable for roadway paving is formulated by mixing very soft penetration asphalt having a penetration value on the order of 300 to 400 and a melt point of 110° F. with recycled or reclaimed asphalt roofing shingles and/or recycled or reclaimed asphalt pavement granule material having a much higher melt point and a much lower penetration value. 10% to 30% of the recycled or reclaimed asphalt material in the final mixture will bring the formulation into compliance with PG grade paving asphalt. The asphalt paving mixture may utilize recycled asphalt shingle granules of approximately 50 mesh in size and preferably between 10 and 50 mesh while a powder may be utilized that is sized below 50 mesh.
