ABSTRACT:
Apparatus and methods for stabilizing soils and other granular materials at the site at which they are located. The apparatus includes a platform, fixed or mobile at a contamination site, carrying a hopper for receiving contaminated material to be stabilized including additives as required, a mixer for introducing additives to the material connected to the hopper, a mechanism for transporting contaminated granular materials from an adjacent contaminated site to the mixer, at least one mold having at least one movable wall, a harmonic compactor to form a uniformly dense, solid compacted preform body, and a discharge station for handling or holding the preform. Where desired or required an air dryer, thermal curing chamber or sintering furnace may be used to dry and/or fuse the preform into a final block. The method includes the steps of introducing a contaminated soil mixture, or other granular material, into a mold having at least one movable wall, applying an appropriate pneumatic preload force to the material in the mold, repetitively accelerating the mold in vibration followed by repetitive impact forces up to, but not exceeding the yield strength of the binding material with the lowest yield strength in the mixture to form a solid preform, removing the preform and allowing it to air dry, or subjecting it to low temperature cure or sintering to stabilize the material contained therein.
