Organic soils are characterized by their high water holding capacity, low shear strength and large compressibility. The properties of organic soil have to be improved before using it for any construction purpose. Lime stabilization is one of the most popular methods used to enhance the properties of clayey soils. Previous studies have shown that the improving effect of lime gets deteriorated in the presence of organic matter with time. In this paper, an attempt is made to study the effect of longer curing period (up to 120Â days) on the geotechnical properties of lime-treated organic soils. The tests were carried out on artificially prepared organic soil mixtures treated with 6 lime. Various laboratory tests like Atterberg limits test, free swell index test, unconfined compressive test and one-dimensional consolidation tests were conducted on artificial organic soil treated with lime at different curing periods (0, 7, 30, 60, 90 and 120Â days) to examine the effect of each parameter. The test results reveal that the effect of lime stabilization is nullified by the presence of organic matter at longer curing periods. The plasticity characteristics of lime-treated organic soils varied with curing period. The unconfined compressive strength of lime-treated organic soil decreased after 90Â days of curing. Compression index of lime-treated organic soil samples increased after 120Â days curing period.
