Khon Kaen loess soil can be classified as a moderate to moderately severe<br>in collapse index. With long term infiltration, its cohesion is almost completely gone. Therefore, this research<br>is aimed to study the behaviors of the bearing capacity and settlement of the compacted Khon Kaen loess soil<br>with and without cement. The testing results from the laboratory and from the field can be shown that the soil<br>and soil-cement stabilization are improved by 95% for modified compaction. This is due to the effects of initial<br>density, initial water content, %cement added, curing time duration and the size of the plate on the bearing<br>capacity and deformation behavior. The results also show that the increasing in water content has the greatest<br>influence to reduce in the bearing capacity but increase in compressibility of the specimens. However, for<br>testing with the same energy of compaction but lower water content, less settlement at any pressures in the<br>unsoaked condition with the more collapse settlement can be found. On the other hand, the 95% modified<br>compaction improvement, the collapse potential/ collapse index are almost negligible. Finally, with more<br>cement added, less settlement with the more bearing capacity can be achieved.</p> ER -
