Compaction Delay Effects on Properties of Lime-Treated Soil
Publication: Journal of Materials in Civil Engineering
Volume 18, Issue 2
Abstract
A statistical study of the effects of compaction delays on properties of lime-stabilized lateritic soil was conducted using two-way analysis of variance and multiple regression analysis. The reductions in mavimum dry density (MDD) and optimum moisture content (OMC) associated with compaction delays are statistically significant at the 5% level, regardless of the compactive effort employed (i.e., standard Proctor or West African Standard). The effects of compaction delays on unconfined compressive stength (UCS) are statistically significant for different compactions, lime contents, and curing. Compaction delay effects on California bearing ratio (CBR) of soil–lime mixtures are statistically significant. The -statistics from regression analysis show that compaction delays significantly influence the measured values of MDD, OMC, UCS, and CBR. It is believed that the findings of this study will be helpful in controlling the compaction delay for lime-treated soils.
