Preliminary Study for Rapid Ground Stabilization

Abstract: The Army has a need to rapidly repair heavily damaged low-volume roads. This report describes the literature review, laboratory study, and preliminary technology evaluation for potential rapid road rehabilitation materials and equipment. The objective was to identify and evaluate equipment, materials, and techniques for rapid road repair. This phase of the study focuses on rapid stabilizers that, when added to native soil, could improve bearing capacity. Lightweight equipment and attachments were assessed for their ability to effectively excavate and place geomaterials. Several commercial soil stabilizers were identified that could meet strength requirements. Equipment attachments for a compact track loader were deemed most suitable for executing rapid repairs.

Expeditionary Ground Rehabilitation for Military-Vehicle Traffic

Abstract: The research objective for this study is to identify and evaluate techniques for soil stabilization to support military-vehicle ground maneuver in contested environments. Various types of stabilizers mixed with silty sand are evaluated in the laboratory for their compressive strength at various soil moisture contents and in the field for their rutting performance. Field data are analyzed for the ability to withstand trafficking from a military ground vehicle by evaluating the rut depth and measured instrumentation data. The field testing shows that the rapid soil stabilization materials and techniques can produce repairs that withstand required traffic without traditional pavement surface materials.
