In parallel with the increasing housing need in parallel with the population growth and the changing needs of the society depending on the continuous technological developments, the strength properties of the soils considered problematic such as high plasticity clay should be improved. In the last twenties when global climate changes started to be experienced, the improvement of the geotechnical properties of such soils that form the basis of engineering structures has become an important issue. Today, natural rocks are one step ahead of other additives in terms of being economical, sustainable and environmentally friendly. Based on this basic idea, in our study, Bayburt tuffite was added to the clay soil by powdering it at the rates of 5%, 10%, and 15% and the strength change after freezing-thawing was examined. The clay soil (CS) + Bayburt tuffite powder (BTP) mixture samples obtained at three different rates were cured in the laboratory environment for 7, 14 and 28 days. At the end of the curing period, the samples were subjected to +20oC, -20oC, 12 hours and 10 cycles in the freeze-thaw cabin and then the strength values were obtained with the Uniaxial pressure tester. The highest strength value after freezing-thawing was observed to increase by 29.55% in the CS + 5% BTP mixture cured for 28 days. As a result, in the light of the obtained data, it was concluded that this mixture ratio can be used as a foundation material in cold climate regions, shallow foundation depths and high plasticity clay soils.
