A method and apparatus for the in situ treatment of soil, sludge, and the like for purposes of remediation, solidification, stabilization, and/or enhancement thereof involves the use of a machine including a mobile carrier and a mixing apparatus mounted thereon for cutting through and mixing strata of an area which is to be treated. The mixing apparatus includes a boom having disposed thereon an endless cutting assembly which is moveable along a looped path, the cutting assembly including a plurality of teeth which convey material downwardly and mix it with underlying material which is to be treated. The cutting assembly is vertically moveable for positioning at a desired depth in the sludge or other material which is to be treated. The method of the invention involves dispensing a treatment material over an area of material, such as sludge or soil, which is to be treated, and thoroughly mixing the treatment material with the material which is to be treated using a machine having a mixing apparatus mounted on a mobile carrier, the mixing apparatus comprising a cutting assembly which is vertically movable for positioning at a desired depth and including a plurality of cutting teeth and impeller teeth which provide thorough mixing of the treatment material with the material which is to be treated.

A method for in situ treatment of material, comprising; dispensing a treatment material over an area of material which is to be treated; disposing a mixing apparatus within said treatment material and said material which is to be treated, said mixing apparatus having an endless cutting assembly which is moveable along a loop path, said cutting assembly including a plurality of teeth which convey said treatment material downwardly and mix said treatment material with underlying material which is to be treated, and mixing said treatment material with said material which is to be treated by moving said cutting assembly along said loop path. A machine for in situ treatment of material, comprising a mobile carrier and a mixing apparatus mounted thereon for cutting through and mixing strata of an area which is to be treated, said mixing apparatus including a boom having disposed thereon an endless cutting assembly which is movable along a loop path around a drive gear and an idler gear said cutting assembly including a plurality of teeth which convey material downwardly where it is mixed with underlying material which is to be treated, said plurality of teeth including a plurality of cutting teeth which break up and loosen soil, and convey material downwardly, and a plurality of impeller teeth which mix and induce loosened material to move upwardly and outwardly, said cutting assembly including a plurality of tooth pads which are linked together by a plurality of connecting links, said tooth pads being cantilevered off of said links and said impeller teeth being located on trailing ends of said cantilevered pads so that distal edges of said impeller teeth sweep outwardly along an arcuate path at a lower end of the boom around said idler gear to prevent loose material from building up under said cutting assembly, and said impeller teeth sweeping back inwardly as they travel between said drive gear and said idler so that they do not interfere with the cutting teeth.
