ABSTRACT
Soil compaction is effective and is realized on site at moisture levels close to optimum of compaction. In periods of excess moisture produced by heavy rainfall or snowmelt, moisture reduction is obtained by adding quicklime. This method was applied to build a compacted cushion consisting of two types of cohesive materials: silty clay with moisture content with 5% greater than the optimum of compaction and loess (collapsible soil) with moisture content with 5…10% greater than the optimum of compaction. The paper presents extensive laboratory tests conducted to determine the optimum percentage of quicklime to reduce the excessive moisture to the optimum of compaction, the degree of compaction achieved by mixing in comparison to the compacted untreated material and the methodology for conducting the mixture and the compaction on site.

Keywords: soil mix, quicklime, degree of compaction
