Guidelines for Stabilizing Problematic Soils Using Calcium-Based Stabilizers

The main goal of the project is to establish protocols for conducting efficient chemical stabilization design for problematic soils with and without soluble sulfates within the state of Montana. Montana Department of Transportation (MDT) has limited experience with chemical stabilization, and while there is a desire to potentially use chemical stabilization, a major concern with this approach is the presence of potential high sulfate concentrations and costs incurred in undertaking chemical stabilization projects. The project will conduct laboratory studies to determine effective chemical stabilizers for stabilizing Montana specific problematic soils. In addition, this project will also perform life cycle cost analysis in order to compare and contrast existing approaches vs. chemical stabilization alternatives in tackling these problematic soils.
