These methods cover procedures for determining the soil-cement losses, moisture changes, and volume changes (swell and shrinkage) produced by the repeated freezing and thawing of hardened soil-cement specimens. The specimens are compacted in a mold, before cement hydration, to maximum density at optimum moisture content using the compaction procedure described in AASHTO T 134.
Two methods depending on soil gradation are covered for preparation of material for molding specimens and molding specimens as follows:
- Method A—Using soil material passing the 4.75-mm (No. 4) sieve. This method shall be used when 100 percent of the soil sample passes the 4.75-mm (No. 4) sieve;
- Method B—Using soil material passing the 19.0-mm (3/4-in.) sieve. This method shall be used when part of the soil sample is retained on 4.75-mm sieve.
