• Abstract:
  This document establishes recommended evaluation criteria to select stabilization type and content, methods of evaluating the effectiveness of stabilization, and methods for moisture conditioning of samples to accelerate the mix design process and to evaluate the effectiveness of stabilization. This revised procedure is an adaptation of the current guidelines for subgrade stabilization, with the addition of chemical analysis of the soil fines to identify clay mineralogy, accelerated curing and moisture conditioning to minimize to time to achieve the mix design and wetting-drying cycles as means of durability indicators. In addition, a static compaction method for preparing fine-grained soil specimens is recommended.
