The U.S. Army Engineer Research and Development Center evaluated the viability of using commercially available polymers mixed with silty sand to create a stabilized base material for concrete or asphalt pavement for both lightweight and heavyweight vehicle traffic. This work was motivated by the difficulty in obtaining optimum materials required to fulfill the military’s mission requirements as well as to diversify available solutions when transportation, handling, or storage constraints rule out other materials. This study is organized to find suitable polymeric soil stabilization materials, methods, and polymer concentrations required for the greatest performance at various moisture contents.When conducting in-situ stabilization under time constraints, stabilization with minimal changes to in-situ moisture while achieving desired compaction and strength is crucial. Methods include studying the current approaches and concentration used for polymeric soil stabilization and verifying the mix ratio to achieve the maximum compressive strength (ASTM D1633), optimum moisture density relationships using a modified compaction effort (ASTM D1557). This study also addresses how these stabilization methods are affected by moisture using a Wet Tube Suction Test (WTST).
