This Small Business Innovation Research (SBIR) Phase II project will develop and demonstrate a novel vitrification process for subgrade soil stabilization. The process includes a method to inject readily available materials into the vitrification zone eliminating subsidence that would otherwise occur as the soils densify during vitrification. The process is based on the use of modifiers that adjust the vitrified soil properties. The Phase I work demonstrated feasibility of the process and that the vitrified material was suitable for subgrade stabilization and resulted in materials having strengths qualified for structural reinforcement applications. Economic analysis completed in Phase I indicated that the method is competitive with conventional subgrade repair methods. The Phase II work will establish the commercial merit of the process by demonstrating its economy, robustness and versatility to produce subgrade synthetic rock from soils in the field. The Phase II work includes participation by a university and an end user. The proposed research and development will yield a fundamental understanding of the relationships between the vitrification process parameters, soil and synthetic rock properties. This will enable optimization of the process in commercial applications.The commercial market for the proposed technology includes soil stabilization of inadequate foundation and slope materials around many kinds of structures including building, bridges and waterways. Customers will be highway departments (state and federal), airport authorities, municipalities and the industrial sector. Essentially, the process will be useful to any entity, including contractors that deal with maintenance of subgrade and/or new construction that have "local" subgrade instability issues to overcome.

这个小企业创新研究（SBIR）第二阶段项目将开发和展示一种用于路基土壤稳定的新型玻璃化工艺。 该方法包括将容易获得的材料注入玻璃化区的方法，从而消除了在玻璃化期间土壤致密化时会发生的沉降。 该工艺基于使用调节玻璃化土壤性质的改性剂。 第一阶段的工作证明了该工艺的可行性，玻璃化材料适用于路基稳定，并产生了具有结构加固应用所需强度的材料。 第一阶段完成的经济分析表明，该方法与传统的路基修复方法相比具有竞争力。 第二阶段的工作将通过证明其经济性、稳健性和多功能性来确定该工艺的商业价值，以在现场从土壤中生产路基合成岩石。 第二阶段的工作包括一所大学和一个最终用户的参与。 拟议的研究和开发将产生一个基本的了解之间的关系，玻璃化过程参数，土壤和合成岩石的性能。 这将使该工艺在商业应用中得到优化。拟议技术的商业市场包括对不适当地基的土壤稳定和多种结构（包括建筑物、桥梁和水道）周围的斜坡材料。 客户将是公路部门（州和联邦），机场当局，市政当局和工业部门。 从本质上讲，该过程将是有用的任何实体，包括承包商，处理路基和/或新的建设，有“局部”路基不稳定性问题，以克服维护。
