Abstract
A process and the product produced by the process in which recycled asphalt shingles are reduced into granules which are then heated to a temperature above 212° F. in order to evaporate any water contained in the material. Once substantially all the water has been evaporated, the heated granules are then placed in a suitable mold and compressed under high pressure to form a block of the desired size and shape after which the blocks are removed from the mold and used on low-traffic volume areas such as patios, sidewalks, driveways, etc.
Claims18
A process for producing blocks from recycled asphalt roofing materials, said process comprising:
- reducing the roofing materials to discrete particles;
- heating the particles in a manner so as to prevent segregation of particles of different sizes and to thoroughly heat all the particles to a temperature greater than 212° F. to evaporate substantially all the water contained in the particles;
- introducing the heated particles into a mold of the desired final product configuration promptly after heating;
- applying sufficient pressure to the particles while in the mold and at about the heated temperature to bind the particles together into a solid product;
- and removing the product from the mold.
An asphalt block formed from recycled asphalt roofing materials that have been reduced to discrete particles, the particles having been heated in a manner so as to prevent segregation of particles of different sizes and to thoroughly heat all the particles to a temperature greater than 212° F. to evaporate substantially all the water contained in the particles and then introduced into a mold of the desired final block configuration, the particles having had sufficient pressure applied to them while at about the heated temperature in the mold to bind the particles together into a solid block.
