Using Geofibers and Synthetic Fluids as Stabilizers for Marginal Soils

This test project explored the use of two soil stabilizers originally developed by Peak Civil Technologies, an Alaskan company, to improve silty soils. The Alaska University Transportation center refined the combination of a plastic fiber (Geofiber 3627BT) and a synthetic fluid (severely hydrotreated paraffinic liquid) that act as a binder in the soil. Early results by the AUTC suggest that the right mix of geofiber, synthetic fluid and water, combined with aging, can improve soil CBR values by at least 100%.
