Abstract

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.

AUTC is this months “UTC Spotlight” for RITA Office of Research, Development and Technology newsletter.

The newsletter focuses on the application, technique and impact of the geofibers & synthetic fluid that was applied at Horseshoe Lake, Alaska. This is part of an ongoing effort by PI & AUTC Director, Billy Connor and Graduate student, Rod Collins to use fine grain material to build roadways and runways in Western Alaska.
