Abstract
The Purpose of this study is to investigate mainly the tensile stress properties of natural and stabilized clayey soil selected from Mosul area .The tensile strengths of compacted specimens of natural soil and lime stabilized soil are obtained using the flexural test (third-point loading). The tensile and the compressive stress-strain curves of both soils are evaluated. The compressive strength on a portion of the beam is determined for both soils. The results reveal that both the tensile and compressive strengths increase with the addition of lime and with the increasing the curing time .Furthermore ,the results show that the tensile strength is more sensitive to lime stabilization than the compressive strength .The stress-strain curves of the stabilized specimens are rather irregular .All specimens, natural and stabilized show sudden type of failure .The method of analysis used for determining the tensile stress-strain curves are the direct method of analysis.
