A study was conducted to determine if vacuum saturation could be used as a rapid and economical method for accurately predicting the freeze-thaw durability of materials such as soil-cement, lime-fly ash, and lime-soil mixtures. Except where the effect of reduced density on soil-cement and lime-fly ash mixtures was to be studied, the stabilized specimens were compacted at optimum moisture content and maximum dry density. Soil-cement and lime-fly ash mixtures at reduced stabilizer contents and lime-soil mixtures cured for different time periods were also tested. Vacuum saturation was accomplished by allowing specimens that had previouly been exposed to a vacuum pressure of 24 in. of mercury for 30 minutes to soak in water for 1 hour at atmospheric pressure. Unconfined compressive strength and moisture content measurements were used to evaluate the durability of the stabilized materials. Comparisons were made with results from an extensive freeze-thaw durability test program conducted at the University of Illinois. Linear regression analyses of the data indicated that there was a significant correlation between vacuum saturation strength and cyclic freeze-thaw strength. A significant correlation was also found to exist between vacuum saturation moisture content and cyclic freeze-thaw moisture content. It was concluded that vacuum saturation provides a rapid and economical method for accurately predicting the freeze-thaw durability of stabilized materials.
