Portland Cement Treatments in Locations with Poor Embankment Material

The Alaska Department of Transportation and Public Facilities (ADOT&PF) is responsible for the construction and maintenance of roadway and airport embankments throughout the State of Alaska. Often, high-quality aggregate is not available in the specific project area, requiring material to be hauled from great distances, resulting in high costs. The ADOT&PF Northern Region Materials Section (NRMS) is considering the use of Portland cement to treat locally available fine-grained soils. Concerns with using cement-treated fine-grained soils are potential frost susceptibility and lack of compressive strength. The research team proposes to test the frost susceptibility and compressive strength of soil samples provided by ADOT&PF NRMS.
