• Abstract:
  The technology embraced by the concentric graphite arc-melter (CGAM) promises to furnish a power tool to provide in-situ stabilization of unstable soils through vitrification. This ensures a new maintenance capability for a myriad of stabilization problems. The project will involve three phases. The first phase entails determination of the geotechnical properties of the resultant vitrified soils, a thorough constructability review and an economic analysis to verify the technology's potential for economic feasibility. Phase 2 will include the development of a prototypical CGAM that can be used in limited field trials to prove the concept under actual environmental conditions. Phase 3 will comprise detailed design and testing of a pre-commercial prototype CGAM system. Phase 3 will also include the development of the required construction techniques and safety systems as well as the design of the quality control instrumentation necessary to permit immediate implementation upon whether to continue onto the next phase based on the results of the completed phase.
