This work aims to study the stress-strain curves of soil samples subjected to tensile stress. The samples (50*50*300 mm) were prepared from lime stabilized gypseous soil using (3%) lime as stabilization percent. The samples were cured at (25,49 and 600C) for a period of (2,15,30,90 and 180) days. The results obtained from flexural tensile tests were analyzed using three methods of analysis. These methods are, the elastic bending theory, direct, and differential method. The elastic and the direct methods gave, generally similar results of the soil flexural tensile stress while the differential method gave lower values. Also the tensile stress-strain curves obtained by the elastic method were consistent, while the curves from direct and differential methods are in consistent, with the exception of the samples compacted at the dry side of the compaction curve.
