SOIL-LIKE MATERIAL AND METHOD OF MAKING A BARRIER FOR CONTAINING WASTE
The invention relates to a low-permeability geotechnical barrier material including a blend of approximately equal parts of: aggregate particles, sand-size particles and manufactured composite particles that include a hydratable sealant material composed of naturally-occurring clay minerals and/or polymer-enhanced clay minerals, such that the actual percentage of clay mineral component is less than 10% by weight in the blended material. In a particular embodiment, the construction of a low-permeability geotechnical barrier using predominantly coarse grain materials by conventional compaction efforts is rarely attempted due to the difficulty of maintaining a uniform mix of well-graded sand and aggregate blends necessary to achieve low permeability. The regularly achievable permeability offered by this material blend when installed with specific proscribed techniques using conventional equipment can be 5×10−8 cm/sec or lower.
