Abstract

This paper presents an experimental study on the influence of wetting and drying on matric suction and moisture content of unsaturated compacted cohesive soils. Three as-compacted states and three levels of compaction energy of soil samples were investigated. Test results show that water content increases upon wetting and results in significant matric suction reduction. The effects are the opposite upon drying. In addition, the effects of as-compacted state and the compaction energy also warrant careful consideration. The matric suction appears to be a sensible parameter to evaluate the effects of wetting and drying of unsaturated compacted soils. However, further study is warranted for engineering application.
