SOIL STABILIZATION FOR REMOTE AREA ROADS -- FINAL REPORT
A laboratory study has been completed which shows that the sands to silty sands typical of the Yukon-Kuskokwim Delta area of Alaska can be significantly improved or stabilized by use of emulsified asphalt and Portland cement. The Yukon and Kuskokwim Deltas are sedimentary areas where the high silt loadings of these rivers are deposited as the river velocities drop on approach to the Bering Sea. Soils are predominantly organic sandy silts, with occasional silty sand deposits. Gravels are generally not present, and are barged in for embankment construction at considerable expense. Samples of the best available soils for roadway construction were taken at each of thirteen different villages. The best of the available materials, fine silty sands, were selected from three sites for laboratory stabilization testing. Stabilizers considered were restricted to asphalt emulsions and cement. The study shows that stability levels can be achieved which should allow use of locally available sands or silty sands for the construction of roadway and airport surfacing and base stabilzation projects.
