Compaction Characteristic of Lime Modified Expansive Soil

摘要：

　　Through compaction test discussed about the compaction characteristics of expansive soil by lime modified in middle of Shandong province.The results show that the optimum moisture content is lower when the expansive soil is cured by dry compaction method,and the maximum dry density is higher.Compaction curve appeared the phenomenon of two peaks when expansive soil is cured by wet compaction method.Lime content of lime improved expansive soil,particle size composition,age and compaction function have influence on compaction curve.With the increase of the quantity of lime,the optimum moisture content increases,the maximum dry density decreases.With the age growth,the optimum moisture content increase slightly,the maximum dry density decreases slightly.The bigger the compaction work,the smaller moisture content is,the larger the maximum dry density is.
