Patent

CA 2068209

A composition, suitable for use as a base in the construction of roads, and other areas, is formulated from an ash-aggregate comprising municipal solid waste incinerator ash, MSWIA, mixed with an aggre- gate material. Upon the addition of cement, compac- tion, and curing, a volumetrically stable solid is formed. All particles greater than 3/8" are removed from the ash-aggregate material prior to the addition of cement. The stable solids immobilize heavy metals in the MSWIA. Incinerator ash, sufficiently small to fit through two inch screen (1) passes into ash bin (3). Belt (5) carries the ash (4) toward mixing chamber (10). This feeds on to screen (26). Streams (34) and (50) are com- bined in bin (54) and cement (60) is added. The combi- nation is mixed, (72) and is ready for transport.
