In this research a set of tests were performed to determine the effect of lime addition and water content on the bearing capacity of cohesive soils. The bearing capacity was measured by the CBR method. Four types of soils were included in the research. Soil samples were prepared from each type by 6 different water content, 4 dosage of lime addition and 3 duration of curing time. It was found, that each soil is suitable for the construction of lime-stabilized pavement layers. As a result of the lime treatment the bearing capacity of each soil was increased. Repeated CBR tests were performed on the treated and untreated soil samples after 4 days of soaking. It was confirmed that the water-sensibility of the treated soils decreased significantly. A regression tree model was ap-plied to create practice-oriented rules for predicting the bearing capacity. Our results support the idea that the bearing capacity of lime-stabilized soil layers can be counted in the total bearing capacity of forestry and agricul-tural road’s pavement.
