Strength and Frost Heave Properties of Lime Stabilized Soil

Abstract

In this paper, lime and slag were added to three types of soils as a stabilizer. The strength and frost heave properties of these soils were evaluated.
When the experimental water content approaches the optimum water content, the long-term strength of stabilization soil with the slag increases significantly. When the experimental water content is relatively high, the lime stabilization method is effective at increasing strength. This implies that the strength of that soil is influenced by the decrease in water content caused by the addition of stabilizers. It was found that lime stabilization could restrict frost heave. The effect of lime stabilization on frost heave was highly significant when the addition rate or curing period increased. Frost heave was proportional to the CBR. It was found that stabilized soil having a CBR of 100 could restrict frost heave ratio below 5%.
