Compaction characteristics and mechanical properties of lime/cement treated granular soils

Soils treated with Lime/cement are used extensively in numerous applications such as the working plat-form, road sub-base and base materials. Various parameters affect the mechanical characteristics of treated soils such as amount of stabilizing agents, initial water content, grain size, particles' size distribution, curing time, and etc. Thus, numerous studies have been performed recently to figure out these effects. In this study, two different types of granular soils are stabilized by lime/cement treatments and the compaction characteristics and mechanical properties of treated soils have been considered. The results show that when the maximum particle size varies from 19mm to 9mm the unconfined compressive strength, maximum dry density of the stabilized soil would decrease and compaction optimum moisture increases significantly.
