Abstract: 
This paper evaluates the effect of lime on mechanical behavior of improved soil. The soil tested is characterized by liquid limit of 49, plastic limit of 17 and plasticity index of 33. Atterberg limits, unconfined compressive and California Bearing Ratios (CBR) have been performed in the soil sample.
In this study, 27 specimens with 3, 6 and 9 percent quick lime and curing period of 28, 56 and 90 days were prepared. The specimens were placed in curing room temperature with 30
°C and 60 percent humidity. Compressive tests were performed on 10x10x10 cm samples.
Three specimens with 3, 6, 9 percent quick lime was compacted under 10, 25 and 56 blows in five layers. The CBR tests were performed on specimen with curing period of 28, 56 and 90 days. The amount of swelling, water content and dry density were measured during different curing periods. The comparison of CBR and compression test results indicates that 6 percent of quick lime and 56 blows for different curing period yield the best result.
