AUTC project number: 207117
This project, funded by ADOT&PF and AUTC, is investigating a new technique for using geofibers and a synthetic fluid to stabilize very loose sandy and silty soils typical of Western Alaska. Lab testing focused on measuring how well these new materials might improve poor foundation soils. Tests have shown that fibers can double or triple the strength of the soil. While the addition of synthetic fluids adds some strength, their primary function is to reduce moisture sensitivity of the fine-grained material.
