Abstract: Since maximum densities resulting from modified compaction efforts are being specified, and obtained, for bases, subbase, and subgrades in airfield design, these higher densities should be utilized in the field of soil cement. The primary objective of this study was to show that increasing maximum densities of soil-cement mixtures to those resulting from modified compaction efforts would allow a reduction in the cement content required to produce a satisfactory soil-cement structure. Laboratory specimens were compacted to maximum modified densities along with specimens compacted to maximum densities resulting from standard compaction efforts. Both groups of samples were subjected to freeze-thaw, wet-dry, and compressive strength tests in order to evaluate the effect of the higher densities on soil-cement.mixtures. The type of soil used was a fine sandy loam, or a type A-2-4, by AASHO classification. As a result of this investigation, it was found that as a result of the higher maximum densities, soil-cement losses were reduced for the freeze-thaw and wet-dry durability tests, and compressive strengths were increased sufficiently to allow a cement content reduction of 3 per cent for the type of soil used.
