The Effect of Clay and Lime Content on CBR Strength of Lime- Stabilized Clayey Sands

Since lime- stabilization is effective on different soil size ranging from sand and finer, the influence of lime and clay content on CBR strength of these soils is investigated. Lime combines with the clay part of these soils and provides cemented materials, which is similar to concrete. Hence, the variation in clay and lime content will affect the amount of cemented materials and consequently the strength. Providing some lime- stabilized clayey sand samples, the effect of clay and lime content on CBR strength is evaluated. The results show that in a particular range of clay content, the mixes have the maximum strength variations and, the optimum lime content is about 7 to 8 percent.
