Abstract

The purpose of this research is investigation the effect of lime on the residual soils in the southern area of the Faghireh village of southern Hamadan. The study area is located in the mountain range of Alvand and Kyvarstan in south of Hamadan. The topography of the region is hilly and formed from the weathered units. To investigate of lime effect on studied soils, maximum dry unit weight, optimum water content, pH and uniaxial compressive strength of stabilized soils with different percentages of lime was determined. The results show that increasing lime percentage and curing time, increases optimum water content and decreases maximum dry unit weight, and also improved the resistance properties of stabilized soil. According to the results, optimum lime percentages were 5% and 7%, and the curing time for the stabilized soils in the Faghireh area of Hamedan were obtained for 28 days. Then, the effects of freez-thaw cycles were investigated by using uniaxial compressive strength tests, direct shear, weight loss due to freezing and determining the Swelling of samples. The results show a reduction in uniaxial compressive strength in freez-thow cycles. Also, the cohesion of the samples are decreased and the internal friction angle of the samples are increased, and the weight loss and Swelling due to the freezing of the stabilized samples are less than the base soil.
